These numbers are located on the rear panel of the unit. Space is also provided for other relevant informationModel NumberSerial NumberDate of PurchasePlace of PurchaseSelecting fine audio equipment such as the unit you’ve just purchased is only the start of your musical enjoyment. Now it’s time to consider how you can maximize the fun and excitement your equipment offers. VocoPro and the Electronic Industries Association’s Consumer Electronics Group want you to get the most out of your equipment by playing it at a safe level. One that lets the sound come through loud and clear without annoying blaring or distortion and, most importantly, without affecting your sensitive hearing.Sound can be deceiving. Over time your hearing “comfort level” adapts to a higher volume of sound. So what sounds “normal” can actually be loud and harmful to your hearing. Guard against this by setting your equipment at a safe level BEFORE your hearing adapts.To establish a safe level:• Start your volume control at a low setting.• Slowly increase the sound until you can hear it comfortably and clearly, and withoutdistortion.Once you have established a comfortable sound level:• Set the dial and leave it there.• Pay attention to the different levels in various recordings.Taking a minute to do this now will help to prevent hearing damage or loss in the future. After all, we want you listening for a lifetime.Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since hearing damage from loud noise is often undetectable until it is too late, this manufacturer and the Electronic Industries Association’s Consumer Electronics Group recommend you avoid prolonged exposure to excessive noise. This list of sound levels is included for your protection.���������������������������Level������������ExampleQuiet library, Soft whispersLiving room, Refrigerator, Bedroom away from traffic Light traffic, Normal ConversationAir Conditioner at 20 ft., Sewing machineVacuum cleaner, Hair dryer, Noisy RestaurantAverage city traffic, Garbage disposals, Alarm clock at 2 ft.��������������������������������������������������������������Level��������������ExampleSubway, Motorcycle, Truck traffic, Lawn MowerGarbage truck, Chainsaw, Pneumatics drillRock band concert in front of speakersGunshot blast, Jet planeRocket launching pad-Information courtesy of the Deafness Research FoundationListening For A LifetimeSpecifi cationsReceiverCarrier Frequency Range: UHF 614~694MHzOscillation Mode: Quartz Controlled Fixed Frequency Stability: 10 PPMSensitivity: 1.6uV @ sinad =12dBMax.

The most common applications and placement techniques are listed below. Keep in mind that microphone technique is largely a matter of personal taste, and there is no one “correct” microphone position.Proximity EffectWhen the sound source is less than ¼ in. from the microphone, the microphone boosts bass frequencies (by 6 to 10 dB at 100 Hz), creating a warmer and richer bass sound than when farther away. This effect, known as proximity effect, happens only in unidirectional dynamic microphones like the UHF-5805.FeedbackFeedback occurs when the amplified sound from any loudspeaker reenters the sound system through any open microphone and is repeatedly amplified. Most commonly, feedback is caused by the following condi-tions: placing loudspeakers too close to microphones, having too many open active microphones, boosting tone controls indiscriminately (mainly treble) and performing in areas with high ratios of room surfaces that have hard and reflective surfaces such as glass, marble and wood. What to do if feedback occurs before the sound system is loud enough?• Request that the talker speak louder into the microphone.• Reduce the distance from the talker to the microphone. Each time this distance ishalved, the sound system output will increase by 6dB.• Reduce the number of open microphones.• Move the loudspeaker farther away from the microphone. Each time this distance isdoubled, the sound system output can be increased by 6dB.• Move the loudspeaker closer to the listener.• Use an equalizer/feedback reducer to cut the frequency bands in which the feedbackoccurs.Microphone Placement & Tone QualityLead & Backup VocalsLips should be less than 3” from or even touching the windscreen on an axis to the microphone. Doing this creates a robust sound, emphasizes bass and provides maximum isolation from other sources.SpeechWhen giving a speech or simply speaking, place the microphone 4” to 10” away from the mouth, just above nose height for a natural sound with reduced bass. You can also place the microphone 8” to 16” away from the mouth, slightly off to one side, for a more “distant” sound with highly reduced bass and minimal “s” sounds.Before getting startedBefore starting any installation procedures, it is recommend to completely unpack all the package contents. The original packaging should be kept in the event that re-shipping is needed. Upon unpacking the UHF-5805, you should have received the following items:•Custom Aluminum Travel Case (1)• UHF-5805 Receiver (1)• Handheld Microphones (4)• 3 ft. male/male ¼” cable (1)• 14V DC Main Unit power adapter (1), 9V DC Charger power adapter (2)• Dual Microphone Charger (2)9V9VUniversal Mic Charger Universal Mic Charger14VTo install the UHF-5805 to a 19” rack case, complete the steps below.1. Attach mounting brackets to the UHF-5805 via the supplied mounting screws.2. Align the UHF-5805 with the desired space in rack and slowly slide in, rear panel first.3. While aligned, use rack case screws (not included) in the order shown below to stabilize the UHF-5805 in its space, using the “X” rotation (numbered below) will ensure even tension and flush alignment.MountingNOTE: Depending on your rack case design, it may be neces-sary to allow for sufficient space for the antennas.NOTE: Do not tighten screws firmly until all screws are in place.����Maintenance proceduresRemoving the Field Replaceable ModulesEach of the 4 microphone modules on the UHF-5805 were designed in a way that allows them to slide out. This is a convenient feature if ever a module needs to be repaired or replaced.1. Remove the two screws that fasten the module to the front panel.2. To remove the module, simply slide the module out of the compartmentNOTE: It might be helpful to use a flat-head screwdriver to nudge the module out of its compartment.3. To re-insert, slide the module into compartment until it is completely secured. Secure the module withthe screws.The UHF-5805 comes with two dual chargers that let you charge all four microphones at the same time.Charging the MicrophonesIf the LED light on the microphone(s) does not light up when the microphone is turned on, this indicates that the microphone needs to be chargedTo charge:1. Place the microphone in the charger slot, the LED on the charger will be lit while the microphone is charging.2. When the LED on the charger turns off, the microphone is charged and can be removed.NOTE: For longest battery life, be sure to turn the microphones off when not in use.Reading the LED IndicatorsThe LEDs on the charger indicate the charging status. There are three states: blinking, on, and off.• Blinking - The power is connected to the charger but there are no microphones being charged • On - The microphone is being charged• Off - The microphone is completely charged and can be removed.Charger and Microphone Descriptions and Functions1.

(With the speakers located in these positions, the possibility of feedback is greatly reduced).• Always check the stage setup before a performance to ensure optimum placement of microphone and monitors.IMPORTANT: Every wireless microphone installation is a unique situation, and can present a variety of prob-lems. Never attempt a live performance without first conducting a “walkthrough” test of the system in the performing area. If major changes (additional wireless systems or intercoms, relocation of scenery, etc.) have been made since the last walk-through test, check the wireless system again, as close to performance time as possible.P.A. Speakers Facing AwayFrom Rear of MicrophoneMonitor Directly BehindMicrophoneOperations2. Adjust the receiver’s VOLUME controls to approximately 50%.3. Switch the microphone’s POWER BUTTONS to the ON positions.4. Talk or sing into the microphones. During normal operation, the RF/AF signal LED’s will light when amicrophone is being used.5. Adjust the receiver’s VOLUME controls until the output levels are balanced w ith each other and otherpossible source output i.e. CD+G tracks.TroubleshootingProblemsNo sound output, RF/AF LED(s) are not glowingReceived signal is noisy or contains extraneous sounds with the microphone(s) ON.There is noise coming from the receiver with the microphones turned OFF.Momentary loss of sound as microphone(s) are moved throughout the operating range.Solutions• Make sure the microphone and receiver power switches and receiver are set to the ON position.• Check microphone charge to ensure there is sufficient power. Charge mic if necessary• Check receiver’s AC power connection.• Make sure antennas are firmly connected and extended to an optimal position.• If necessary, reduce the distance between the microphones and receiver.• Turn up the receiver’s VOLUME level controls.• Check for proper connection between receiver and external amplifier/mixer.• Talk into the microphone and observe the receiver’s RF/AF signal LED’s. If they glow, the problem is elsewhere in the sound system.• Check microphone(s) charge and recharge if the charge is low.• Remove local sources of UHF interference, such as lighting equipment.• Adjust the squelch controls on the front of the UHF-5805 receiver.• Signal may be too weak. If so, reposition antennas. (If possible, move them closer to the transmitter).• Remove local sources of UHF interference, such as lighting equipment.• Reposition the receiver or antennas.• Reposition the receiver, perform a “walkthrough”, and observe the signal strengths. If audio dropouts persist, mark these “dead spots” in the operating area and avoid them during the performance.UHF-5805 Manual © VocoPro 2011V 1.1Erratic LED blinking on the main receiver modules• Make sure the 14V power adapter is pluggedin to the main unit.

February 2020—Firmware and FAA RID NPRMAs February greets us many have chosen to set theirhobby interests aside, or at least limit their participa-tion to inside for the past couple months. The winterbuild is a time-honored tradition in the northern cli-mates. In addition to getting new aircraft ready forwhen the weather warms and the winds calm it’s theperfect time to give our existing airframes a thoroughexamination for signs of wear, or potential failure. It’salso a good time to check to see if our transmitters, re-ceivers, or ESC’s may have pending firmware updates.The advantage of firmware updates is they often givenew capabilities for your existing hardware, or fix pre-viously unknown defects. However, sometimes as newfeatures are introduced or patched another featuremay be inadvertently broken by the update. The avail-ability of an update does not mean it’s necessary foryour use. As an example, when Futaba released up-date 7 for the Futaba14SG they inadvertently intro-duced a range check failure on startup. Futaba recent-ly introduced update 9 to fix the range check failure onstartup issue. Firmware updates tend to be an iterativeprocess with customers being the final test of function-Futaba Software DownloadFrSky Important Update for ACCST D16 FrSky Firmware Downloads Spektrum Firmware Updates Jeti Firmware Updates Graupner Updates Castlelink UpdatePersonal safety is not the only topic to discuss this month. The survival of our hobby is very much threatened by the recent FAA RID Notice of Pro-posed Rulemaking (NPRM). The FAA published their plan requiring broadcast from all aircraft weighing over 250 grams (0.55 pounds) on Dec 31. ality. FrSky recently released a new firmware for ALL of their D16 ACCST transmitters and receivers back to 2013 (OpenTX as well as FrOS). The firm-ware addresses a serious issue –if you’re in the Eu-ropean Union. The FCC (American) version of transmitters/receivers are not significantly affect-ed, especially if operated where the airwaves are not crowded with many 2.4ghz signals. One take-away from this is noting that when applying radio firmware updates be sure to note that you have downloaded FCC version and not EU. I recom-mend waiting on the FrSky ACCST updates for a couple months as this is a major update and there will inevitably be bugs. I’d rather do the updates one time since this transmitter update also requires that all receivers are updated.In summary; when checking over all the clevises, horns, pushrods, screws, motor mounts etc, don’t forget to check where you stand regarding what you can’t see –the firmware. Additionally, be judi-cious about applying a recently introduced firm-ware especially if it’s a major update. Finally, be sure you’re using the FCC radio firmware and not the EU version.Don’t be misled by the term “drone” in the NPRM. The FAA uses the term “drone” to apply to all Un-manned Aircraft Systems(UAS), this includes every-thing we fly at TCRCM field and may even include free flight and control line. This NPRM is open for public comment until March 2. The AMA, and EAA (Experimental Aircraft Association) as well as others petitioned in vain for an extension to the comment period. In response to the request for an extention FAA replied on January 28:“…the need for remote identification of UAS increas-ingly has become important as new public safety and national security concerns arise regarding the use of UAS. Accordingly, the FAA has determined that any extension of the comment period, and the subse-quent delays in promulgation of a final rule imple-menting remote identification of UAS, would not be consistent with the safety and security objectives of the proposed rule.Therefore, your request to extend the comment pe-riod for the Remote Identification of Unmaimed Air-craft Systems NPRM is denied. The comment period for the NPRM closes on Monday, March 2, 2020.”Once one dives into the 319 page NPRM in depth it details how the FAA is proposing to progressively annihilate the hobby. This NPRM proposes to make it illegal for a land owner to fly over their own land in the short term, and eventually eliminate model flying fields for home-built aircraft like we now fly. There are many many levels of concern. Grouping Line of Sight (LOS) modeling in with the regulations of Beyond Visual Line of sight BVLOS operations is a one size fits all solution that is inappropriate. Making it impossible to establish new flying fields, or even move an existing club flying field to a new location is well beyond what Congress mandated in the FAA reauthorization act of 2018. To assist with digesting the information about the NRPM, Jim Andersan has posted a page of infor-mation on the Club Website. There are also links to two summaries of the NPRM in the sources below.It’s seriously imperative that all interested reach out to the FAA and to all elected representatives. Even if your position is that you have no intention of follow-ing these rules then politely tell the FAA that they can expect noncompliance from otherwise law abid-ing citizens.Some would say that contacting FAA or representa-tive will make no difference. If that’s the case we’re no worse off and you did what you could. Your com-ments MAY make a difference in which case it’s time and energy well spent.Links to Contacts:• Dan Newhouse• Patty Murray• Maria Cantwell• White House• FAA RID NPRM Comment pageLinks to Information and resources.• Layman’s Guide to the NPRM for Remote ID• AMA summary of the RID NPRM• AMA Templates to use to assist in drafting your own response.• Our club website。

The twin input terminals allow for daisy-chaining of supply (max. 10A).A green LED on the front of the unit indicates that power is on, and a red LED illuminates during error conditions.In the event of a field wiring or barrier fault from any barrier on the Power Rail, the integral collective error messaging relay alerts the controller via a single digital I/O point. This relay can be configured as normally open or normally closed.Additionally, the bus implemented in the Power Rail isforwarded to the outside terminals 13 and 15 for usage with KFD2-WAC2-Ex1.D RS 485 connection. Terminal 14 is only for test purposes.In the sense of functional safety (SIL) the device provides no dangerous failures. Thereby the safe condition of the supplied barrier must be defined as the powerless state. Thus the device will not influence the safety calculation or the SIL value.This device is compatible with all versions of the Power Rail and provides group fusing.Note: Redundant systems require two KFD2-EB.R4A.B modules.FeaturesFront view16-05-23 12:04D a t e o f i s s u e 2016-05-23189784_e n g .x mlSupplyConnection terminals 11+, 12-terminals 8+, 9-Rated voltage U n20 ... 30 V DCThe maximum rated operating voltage of the devices plugged onto the Power Rail must not be exceeded.Power dissipation ≤ 2.4 WOutputSupply Output current: ≤ 4 A Fault signal relay output: NO contactContact loading30 V AC/ 2 A / cos φ ≥ 0.7 ; 40 V DC/ 2 A Energized/De-energized delay approx. 20 ms / approx. 20 msFuse rating5 Arecommended maximum utilization of the fuse: 80 %Directive conformity Electromagnetic compatibilityDirective 2014/30/EU EN 61326-1:2013 (industrial locations)ConformityElectromagnetic compatibility NE 21:2006Degree of protection IEC 60529:2001Ambient conditions Ambient temperature -20 ... 60 °C (-4 ... 140 °F)Mechanical specifications Degree of protection IP20Mass approx. 100 gDimensions 20 x 119 x 115 mm (0.8 x 4.7 x 4.5 in) , housing type B2Mountingon 35 mm DIN mounting rail acc. to EN 60715:2001Data for application in connection with Ex-areasStatement of conformityTÜV 00 ATEX 1618 X Group, category, type of protection, temperature class ¬ II 3G Ex nA nC IIC T4Directive conformityDirective 2014/34/EU EN 60079-0:2012+A11:2013 , EN 60079-15:2010International approvals FM approval Control drawing 116-0160Approved for Class I, Division 2, Groups A, B, C, D; Class I, Zone 2, IIC UL approvalApproved for Class I, Division 2, Groups A, B, C, D; Class I, Zone 2, IIC CSA approval Control drawing 116-0160Approved for Class I, Division 2, Groups A, B, C, D; Class I, Zone 2, IIC IECEx approval IECEx UL 16.0051Approved for Ex nA nC IIC T4 Gc General information Supplementary informationStatement of Conformity, Declaration of Conformity, Attestation of Conformity and instructions have to be observed where applicable.

Chapter 14桟onstruct, Deliver, and Maintain Systems ProjectsTRUE/FALSE1. The detailed design phase of the Systems Development Life Cycle is a linear process with each of fivesteps occurring once and in its proper sequence.ANS: F2. In a Computer Aided Software Engineering (CASE) environment, the most important use of a dataflow diagram is to present a graphic display of the system.ANS: F3. During maintenance of a system developed using Computer Aided Software Engineering (CASE)tools, changes to the system are made directly through the data flow diagram.ANS: T4. The Computer Aided Software Engineering (CASE) coding model transforms the structure diagraminto computer code.ANS: T5. If system development is conducted properly, most system maintenance costs can be eliminated.ANS: F6. The context level data flow diagram is a physical input to the lower CASE models that automaticallyproduce program code.ANS: F7. The design and programming of modern systems follows one of two basic approaches: the structuredapproach and the object-oriented approach.ANS: T8. The concept of reusability is central to the structured approach to systems design.ANS: F9. In the object-oriented approach to systems design, a vendor is an example of an attribute.ANS: F10. In the object-oriented approach to systems design, an instance is a logical grouping of individualobjects which share the same attributes and operations.ANS: F11. In the object-oriented approach to systems design, when an operation is performed on an object, anattribute will always be changed.ANS: F12. In the object-oriented approach to systems design, inheritance means that each object instance inheritsthe attributes and operations of the class to which it belongs.ANS: T13. In the object-oriented approach to systems design, it is possible for an object class to inherit attributesand operations of another object class.ANS: T14. The entity relationship diagram is used to represent object-oriented designs.ANS: T15. Office automation is more complex than accounting packages.ANS: F16. In-house developed systems are less reliable than commercial software.ANS: T17. Output of the Management Reporting System may vary considerably among companies.ANS: T18. Output reporting includes both paper and electronic reports.ANS: T19. Information as to which databases are required for a new system can be obtained from the entityrelationship diagram.ANS: T20. A point-of-sale terminal is an example of electronic data input from source documents.ANS: F21. Correctly designed, processing modules are tightly coupled and have strong cohesion.ANS: F22. A system walkthrough occurs after the system is implemented.ANS: F23. The detailed design report is the 揵lueprint which guides programmers and database administratorsin constructing the physical system.ANS: T24. When a program module is tested, both good and bad data are included with the test transactions.ANS: T25. Instruction for the filling out of paper input forms should always be printed on a separate instructionsheet.ANS: F26. Program modules with weak cohesion are more complex and difficult to maintain.ANS: T27. If individual modules are thoroughly tested, it is not necessary to test the whole system.ANS: FMULTIPLE CHOICE1.

An advantage of the Computer Aided Software Engineering (CASE) model tool, which transforms thestructure diagram into machine language, isa. it facilitates the auditors review of the systemb. it ensures that firm will use a specific CASE tool and vendorc. it forces all system changes to be made through the data flow diagramsd. it reduces the analysis required in designing the systemANS: C8. When maintaining a system that was developed using Computer Aided Software Engineering (CASE)tools,a. the programmer must thoroughly review the program codeb. changes should be made directly to the structure diagramc. significantly less time is required compared to maintenance activities for a systemdeveloped without using Computer Aided Software Engineering (CASE) toolsd. the need for testing the modified application is eliminatedANS: C9. Which of the following is an advantage of the Computer Aided Software Engineering (CASE)approach?a. the ability to easily revise the model during the development stageb. the requirement that all program code and documentation be regenerated for each modulec. the cost of software engineering programsd. user involvement is restricted to final stages of developmentANS: A10.

Using Computer Aided Software Engineering (CASE) tools, the structure diagram can be transformedinto machine code. Describe a disadvantage associated with this procedure.ANS:Auditors need to review program code, and machine code is more difficult to review than source code.Also, this approach usually commits the company to a particular CASE tool and vendor while source code is accepted by most CASE tools.2. Using Computer Aided Software Engineering (CASE) tools, the structure diagram can be transformedinto machine code. Describe an advantage associated with this procedure.ANS:Programmers are forced to make all changes through the data flow diagrams. The CASE tool will then modify the structure diagram and rewrite the machine code automatically. This ensures that thesystems documentation always agrees with the computer code.3. What is prototyping? Why is it used in systems development?ANS:Prototyping is a technique for providing users with a preliminary working version of the new system that users can test. This leads to better understanding of user needs and system requirements. When used in the early stages of the SDLC, prototyping is an effective tool for establishing userrequirements.4. A bottom-up method to design a new system by assembling reusable modules is called__________________________.ANS:object-oriented design5. Contrast the structured and object-oriented approaches to conceptual systems design. Which is morecommon?ANS:The structured approach develops each new system from scratch from the top down. Object-oriented design builds systems from the bottom up through the assembly of reusable modules rather thancreating each system from scratch. The structured approach dominates modern system design while the object-oriented approach is still an emerging concept.6. What is meant by 搊bject-oriented design? What does it mean for systems design?ANS:Object-oriented design refers to a 揵uilding block approach to system design which developssystems from reusable standard components, called objects. This approach avoids starting from scratch for each new system. This saves time and expense for development, maintenance, and testing ofsystems.An example of an object is inventory. Each object possesses two characteristics: attributes (partnumber, description, quantity on hand, . . .) and operations (reorder, replace, review quantity, . . . )7. List three advantages and one disadvantage of commercial software.ANS:Advantages include very quick implementation time, relatively inexpensive software, and reliable, tested software.Disadvantages include not being able to customize the system and difficulty in modifying the software.8. What is the purpose of the Request for Proposal (RFP)?ANS:The purpose of the RFP is to obtain proposals on supplying commercial software packages fromvarious vendors. Each prospective vendor is sent an RFP explaining the nature of the problem, the objectives of the system, and the deadline for proposal submission. The RFP includes a format for responses to facilitate a comparison of the proposals from different vendors.9. Explain how a benchmark problem is used to measure the performance of two different commercialsoftware packages.ANS:Each prospective vendor is given the same data and task to perform (usually important transactions or tasks performed by key components of the proposed system). The results of the benchmark problem are compared for speed, accuracy, and efficiency.10. Contrast the structured and object-oriented approaches to conceptual systems design. Which is morecommon?ANS:The structured approach develops each new system from scratch from the top down. Object-oriented design builds systems from the bottom up through the assembly of reusable modules rather thancreating each system from scratch. The structured approach dominates modern system design while the object-oriented approach is still an emerging concept.11. List three characteristics that should be considered when designing a hardcopy input form.ANS:handling, storage, number of copies, form size12. List two techniques of forms design that encourage efficient and effective data collection.ANS:zones and embedded instructions13. What is the importance of the base case?A base case is test data that documents how the system performed at a point in time, and it provides areference point for analyzing the effects of future system changes. The base case also eases the burden of recreating test data.14. Describe a risk associated with the phased cutover procedure for data conversion.ANS:Incompatibilities may exist between the new subsystems and the yet-to-be replaced old subsystems.15. List the attributes of output views.ANS:relevance, summarization, exception orientation, timeliness, accuracy, completeness, conciseness16. What are embedded instructions? Why do they matter?ANS:Embedded instructions are placed directly on the form in the zone to which they pertain. Whencontained in the form, they cannot be lost; when in the relevant zone there is less confusion.17. What are the two methods of electronic input? How do they differ?ANS:The two basic types of electronic input are input from source documents and direct input. The former involves the collection of data on paper that is then transcribed. The latter involves direct capture of data in electronic form. There is no physical record of the input.18. Describe the Cold Turkey (or Big Bang) approach to system cutover.ANS:Under the cold turkey cutover approach (also called the 揃ig Bang approach), the firm switches to the new system and simultaneously terminates the old system. When implementing simple systems, this is often the easiest and least costly approach. With more complex systems, it is the riskiest.19. Discuss the advantage of the parallel operation cutover approach.ANS:Parallel operation cutover involves running the old system and the new system simultaneously for a period of time. The advantage of parallel cutover is the reduction in risk. By running two systems, the user can reconcile outputs to identify errors and debug errors before running the new system solo.20. What is the objective of a post-implementation review?ANS:The objective post-implementation review is to measure the success of the system and of the process after the dust has settled.ESSAY1. Describe at least four advantages and two disadvantages of the Computer Aided Software Engineering(CASE) approach.Advantages of the CASE approach include:reduced system complexityincreased flexibility in making revisions to the system modelcreation, comparison, and review of alternative system designsquicker development processprototyping promotes user involvementreusable program code and documentationreduced maintenance costsDisadvantages of the CASE approach include:cost of the CASE toolstime and cost involved with developing CASE expertiseCASE products are incompatible with one anotherinefficient source code generated by CASE tools encourages skilled programmers to modify the code which results in discrepancies between the data flow diagram and the program code2. CASE tools develop systems without the intermediate step of writing human readable source code.This can pose some concerns for accountants. What are they?ANS:The absence of human readable source code has implications for accountants, auditors, andmanagement. The first is one of control. Source code has traditionally been part of systemdocumentation. Auditors often design test procedures based on the source code. Without it, testing is hampered. In addition, the absence of source code may tie the firm to the CASE tools and vendor, limiting management抯choice.3. Discuss the appropriate steps to take when selecting a commercial software package.ANS:When selecting a commercial software package, the first step is to prepare a needs analysis, as detailed as the user抯technical background permits. The second step is to send out a request for proposal, explaining to the vendor the nature of the problem, the objectives of the system, and the deadline for proposal submission. The third step is to identify and capture facts about each vendor抯system.These facts come from vendor presentations (including a technical demonstration), comparing the results of a benchmark problem, obtaining information about vendor support, and contacting user groups. The final step is to evaluate the findings and make a selection. A weighted factor matrix is used to analyze the qualitative variables, and the results are reported as a performance/cost index.4. The Studebaker Company is evaluating two proposals for a commercial software package. Threerelevant factors were identified and weighted. Then the evaluation team assigned raw scores from 1 to5 to each factor for each vendor. Proposal One will cost $70,000 and Proposal Two will cost $65,000.Proposal ProposalWeight One TwoVendor support 30 4 5Ease of use 30 5 4Range of capabilities 40 5 3Determine a composite score and a performance/cost index for both proposals. Which proposal is the more economically feasible choice?The composite score is 470 for Proposal One and 390 for Proposal Two. The performance/cost index is 6.7 for Proposal One and 6.0 for Proposal Two. Based on this analysis, Proposal One is the more economically feasible proposal.5. Discuss the advantages and disadvantages of the three methods of converting to a new system: coldturkey cutover, phased cutover, and parallel operation cutover.ANS:Cold turkey朤his is the fastest, quickest and least expensive cutover method. It is also the most risky.If the system does not function properly, there is no backup system to rely on.Phased cutover朤he phased cutover avoids the risk of total system failure because the conversion occurs one module at a time. The disadvantage of this method is the potential incompatibilitiesbetween new modules that have been implemented and old modules that have not yet been phased out.Parallel operation cutover朤his is the most time consuming and costly of the three methods, but it also provides the greatest security. The old system is not terminated until the new system is tested foraccuracy.6. What issues must be considered in designing hardcopy documents?ANS:The issues to be considered in designing hardcopy documents relate to the physical operations of the business. Handling: designers must take into account moisture, manipulation, temperature, etc. Storage: where, why, environment, time. Number of copies: how many are needed, where will they be stored, etc. Forms distribution sheets can help determine the number of copies needed. Form size: should be standard unless special circumstances are involved.7. What is the role of test data? What is a base case?ANS:Test data is hypothetical data with known results. The test data is run through the system to verify the processing occurs correctly. Test data should test all aspects of the new system including error capture.When a thorough set of test data is developed, it is saved to document system performance at the time of testing. This is the base case. It can therefore be compared to results of test data after systemmodification.8. Correctly designed modules possess two attributes. Name and explain each.ANS:Coupling measures the degree of interaction or exchange of data between modules. A loosely coupled module is independent of the others. Modules with a great deal of interaction are tightly coupled.Cohesion refers to the number of tasks a module performs. Strong cohesion means that each module performs a single, well-defined task.。
