This supply should deliver either 5V-15V or 12V-27V depending on the model of boost converter fitted.For Type 1 (IEEE802.3af) applications the EvalAg7x61 can be fitted with an Ag7200 isolated boost converter for a maximum power output of 20W. With the Ag7200 fitted the EvalAg7x61 should be supplied with a DC Power supply of 5V-15VFor Type 2 (IEEE802.3at) applications the EvalAg7x61 can be fitted with an Ag7100 isolated boost converter for a maximum power output of 40W. With the Ag7100 fitted the EvalAg7x61 should be supplied with a DC Power supply of 12V-27VAdditionally, the EvalAg7x61 can be supplied from an auxiliary DC Power supply delivering between 44V and 57V to J4.Both DC jack connectors J3 and J4 are configured with the positive supply connected to the centre pin and 0V to the outer ring.DC/DC AdjustThe output voltage of the Boost module can be adjusted by moving the jumper on DC/DC Adjust headers between LK7 and LK8. Placing the Jumper on LK8 will result in the output of the DC/DC converter being set to 48V. Removing the jumper from LK8 and inserting it on LK7 will result in the DC/DC converter outputting 57V.If a different voltage is required, please contact Silvertel for more details.DataA data source can be connected to the Data port J100 via RJ45 connector. This data will be transposed onto the Data and Power output port J101 via the data transformer. The data traces on the evaluation board have been designed to pass through10/100/1000/10GBASE-T Ethernet data signals. No processing or amplification of this signal will be performed on the evaluation board6 Auxiliary SupplyThe Auxiliary supply port, J4, can be used to either inject a secondary supply for theAg6120 or as an output so that the fitted DC/DC converter can be used to power external devices.If J4 is used as an output, it is important to remember that there is an OR-ing diode fitted to the EvalAg7x61, so there will be a voltage drop on the output of the Boost converter.7 PSE OutputPower option selectThe Ag6120 has an option to select its output power and class. These can be chosen by placing a jumper on the appropriate pins of LK6. The power option select should be set while the Ag6120 is powered off, if the power option is changed while the device is powered, the change will not occur until after the Ag6120 output has been power cycled.Mode Classificationtype*2Maxoutputpower*3Connectedpair sets*4Legacy Type 2 (at)*1 IEEE802.3at 38W Either 2Type 1 (af) IEEE802.3bt 20W Either 2Type 2 (at) IEEE802.3bt 38W Either 2 Legacy high power at + legacy class 5 75W All 4BT 1 pair (bt class 5)*5 IEEE802.3bt 46W Either 2/all 4BT Type 3 (bt class 6)*5IEEE802.3bt 75W All 4Table 1: option selections and limits*1 Not recommend for new designs only for use as drop in replacement of the Ag6100*2 See section 5.5.2: Classification of the Ag6120 Datasheet for details*3 See sections 5.7: Output Current Limits & 5.8: Output Power of the Ag6120 Datasheet for details*4 See section 5.4: Port Output of the Ag6120 Datasheet for details*5 Compatible with IEEE802.3bt single signature PDsPairset SelectThe EvalAg7x61 contains four links LK1-4 that connect the pairsets to the outputs of the Ag6120. In order to enable power transfer down a given pairset a jumper should be inserted onto the relevant link or removed if power is not desired down that given pairset. Pairsets 1-2 and 4-5 are connected to the positive output of the Ag6120. While pairsets 3-6 and 7-8 are connected to the negative output of the Ag6120. In high power modes all four jumpers should be fitted.When only two pairsets are to be connected, in order to guarantee operation either pairsets 1-2 & 3-6 should be connected or pairsets 4-5 & 7-8 should be connected.OperationTo ensure that the Ag6120 does not apply power to a non-PoE enabled device the output port first checks for a valid PoE signature. If the Ag6120 does not see a valid signature then it will disconnect, wait approximately 2 seconds then try again. Once a valid signature has been detected the Ag6120 will then perform classification to determine the power requirement of the PD, only after this has occurred will the Ag6120 supply power to the powered device.Status OutputThe Status LED will illuminate if the Ag6120 is providing power to the output port. It will also flash as per the table below when an error has occurred. If this functionality is not desired, it can be disabled by removing the jumper on link LK5.Fault Condition Status Pulses (200ms)Short Circuit 1 x FlashOver Current 2 x FlashesSignature/Class Error 3 x FlashesInput Voltage < UVLO limit 4 x FlashesTable 2: Status Output8 Test SetupFigure 2 shows the basic set up using the EvalAg7x61 evaluation board fitted with anAg6120 and Ag7100 for a Type 2 PSE setup capable of supplying the application with up to 40W of power.

The codec is used to digitise incoming audio from the microphone into PCM data and convert the PCM digital audio output of the Bluetooth chip into an analogue signal for the headphones. The codec board has a microphone input and headphone output which are compatible with standard PC headsets.The W681630 codec has several features such as power down mode and high pass filter disable (to allow frequencies down to DC to be used). The ACC-005 codec evaluation board provides options to allow these features to be tested.The W681360 incorporates a feature that allows the volume of the codec output to be digitally controlled via 3 bits of the PCM data stream. The BISM II provides an AT command (ATS589) that allows you to control the volume of the codec.This document provides you with information to prototype and evaluate your own audio application. Once you have tried out your application, you will be able to design your own audio solution based around the Winbond codec and the EZURiO Bluetooth Intelligent Serial module.Bluetooth is a trademark owned by Bluetooth SIG, Inc., USA and licensed to EZURIO Ltd.2.OverviewThe codec board is powered by an on-board 3.3V regulator to reduce noise to a minimum. The PCM control signals for the codec go directly to the Bluetooth module on the motherboard via the 10-way connector, as do the 3 push button switches. This allows the switches to be used with an external program that implements the upper portion of headset or Handsfree profile.The microphone input, designed to interface to PC compatible headsets, has a fixed gain of 16 set by external components to the codec (the amplifier itself is part of the codec). Part of the microphone signal is mixed into the headphone output signal via VR2. This feature is known as “sidetone” and allows the user to hear their own voice when speaking. It is commonly used in telephony applications to give the user the necessary audio feedback that their ears expect.The audio output gain is by default fixed at 1. By fitting VR1, the audio gain can be made adjustable.The 120mW stereo output amplifier U3 ensures that the codec board can drive standard 32Ωstereo headphones while keeping total harmonic distortion down to 0.1%.Component PlacementNote that not allcomponents are fitted –non-fitted components areshown without pads. Referto Section 7 for details ofcomponent fitment andspecification.3.Codec Board Quick Start Guide3.1 Getting StartedThe codec board is supplied with a right angle, 10 way connector that can be used to connect it to the main developers kit. If required, this should be soldered to the main board. Alternatively other connectors or ribbon cables can be used.3.2 Equipment Required (not supplied)•Headsets (with microphone) (Standard PC headsets are fine)•EZURiO Wireless Developers Kit•BISM II Bluetooth module (Firmware release V9_20_22 onwards supports audio volume control)Normally two sets of development kit are required to test both ends of an audio link. If an application is being developed with an existing endpoint, such as a mobile phone or headset, only one set may be needed.3.3 Motherboard Jumper SettingsBefore using the codec board, there is a jumper setting on the motherboard that needs to be checked. This is CB1, next to the USB adaptor, which must be removed. If fitted it will short out the PCM output from the codec and prevent it operating. CB1 is only relevant for the WLAN 802.11 data module.3.4 Procedure:1)Plug the BISM II into the socket on the Dev Kit, connect to a PC serial port and power up.See the dev kit manual for different power supply options.2)Check that AT commands are working using EZURiO terminal. (Refer to blu2i Quick StartGuide if needed)3)Run the “ATI3” command to find out the firmware release number. If it is less thanV9_20_22, contact EZURiO to get a firmware upgrade for the BISM II. (Note: older versions of firmware will work, but audio output will be at half the full volume and the ats589=7 command will not be recognised)4)Power down, plug the codec board into the dev kit and power up. Check that ATcommands are working.Configure the Slave unit as follows:AT&F* Restore system defaultsATZ Reset the unit= 4 Makeconnectable and discoverableATS512ATS0=1 Answer after 1 ringATS531=1 Keep AT command mode going after a connection isestablishedATS589=7 Set Max. Volume level (requires firmware V9_20_22)AT&W Save the above settingsATZ Reset the unit.5) Find out the Bluetooth address of the Slave Unit by typing ATI4<return>6) Configure the Master Unit as follows:AT&F* Restore System DefaultsATZ Reset the unitATS531= 1 Keep the AT commands going after a connection isestablishedATS589=7 Set volume to maximumAT&W Save to flashATZ Reset the unit.ATD008098nnnnnn Connect to the slave (substitute your slave’s Bluetoothaddress that you found in step 5 for nnnnnn)AT+BTA1 Establish an audio link – displays AUDIO ON on both sides.(Alternatively AT+BTA7 can be used and the units willnegotiate the best link type.)An Audio link is now established between the two units.AT=BTA0 will turn off the audio link (but still leave the units connected).To change volume use ATS589. ATS589=0 gives minimum, ATS589=7 gives maximum. 4.Bluetooth SCO Links – A Primer4.1 Normal SCOBluetooth uses a Synchronous Connection-Orientated link (SCO) for audio. All this means is that for an audio link, the bandwidth needed to maintain the data rates required by the audio link is pre-allocated between the master and slave. This ensures audio data is always transmitted at the required data rate, and takes priority over the transmission of digital data.The Bluetooth specification for SCO is such that there is no re-transmission if data is corrupted or lost. This explains the crackling and popping that occurs when you get to the limits of radio range.The actual data rate over the air is 64 kbits/sec. There are 1600 timeslots available per second and when a master transmits a SCO packet in one timeslot, the slave replies with its SCO packet in the next. The SCO packet size is fixed at 240 bits (30 bytes). This means when a SCO link is established using the HV3 packet type, two out of every 6 timeslots are used up by the SCO link. This means there is enough bandwidth to have up to three SCO links active between a master and slave at the same time. In this scenario, there are no spare timeslots for other data.There are 3 main types of SCO packets, HV1, HV2 and HV3 (High Quality Voice). As mentioned earlier, the HV3 packet type has a 1 to 1 mapping between incoming audio data and the data transmitted over the air. There is no error correction possible with HV3.With HV1, each bit is transmitted 3 times and a simple voting algorithm is used at the other end to correct for any bit errors. This means that only 10 bytes of actual audio data can be transmitted in a SCO packet. To maintain the 64 kbits/sec data rate, all 6 timeslots have to be used for the SCO link, leaving no bandwidth available for data.With HV2, an FEC algorithm is used to correct for 1 bit errors. This increases the data packet size by 50%. This means that only 20 bytes of actual audio data can be transmitted in a SCO packet. To maintain the 64 kbits/sec data rate, 4 out of every 6 timeslots are used for the SCO link.AT+BTA1 enables HV3AT+BTA2 enables HV2AT+BTA4 enables HV1AT+BTA7 allows the link manager to negotiate which packet type to use, the default is HV14.2 Enhanced SCOEnhanced SCO or eSCO was implemented as part of the 1.2 Bluetooth Core Specification Release. The main driving factor was to improve audio quality. This has been achieved by: 1)including a CRC as part of the audio data packet to allow error detection and a re-transmission request. 2)allowing higher data rates by using packets that span more than 1 timeslot 3) allowing asymmetric links to allow high quality audio to be streamed in one direction.eSCO offers significantly better audio quality, but has to be configured at both ends of the link before a unit is enabled to accept incoming connections or enquiries.To try out eSCO, add the ATS584=1 command to the commands listed in the quick start section immediately after the AT&F* and ATZ commands.Both ends of the link must be configured for eSCO for the audio link to be established. If one end is set to eSCO and the other to SCO, you will get an “AUDIO FAIL” when the AT+BTA1 command is issued.The following are the packet types associated with the AT+BTA commands for eSCO.AT+BTA1 – EV3 packet. Up to 30 bytes + CRC. Uses up 1 timeslotAT+BTA2 – EV4 packet. Up to 120 bytes + CRC + 2/3 FEC. Up to 3 timeslotsAT+BTA4 – EV5 packet. Up to 180 bytes + CRC. Up to 3 timeslots. Currently Unsupported4.3 SCO / eSCO Transport DelaysThe following delays have been measured between incoming audio and audio output at the other end of a Bluetooth link.Normal SCO: AT+BTA1 7.84 ms AT+BTA2 9.24 ms AT+BTA4 10.8 msEnhanced SCO AT+BTA1 12.1 ms AT+BTA2 33.4 ms AT+BTA4 41.2 msAs can be seen, the additional error correction of eSCO comes with a transport delay penalty. This is because a buffer is needed to ensure that there is still data to output while waiting for a corrupted data packet to be re-transmitted.For AT+BTA1 and normal SCO, the data is transmitted once every 6 timeslots so the transport delay is expected to be 6/1600 = 3.75ms. When doing loop-round testing with the codec, i.e. with no transport delay, it was found that from input to output, the codec added ~1ms of delay at 1kHz and 1.5ms at lower frequencies.4.4 PCM TimingThe codec samples at 8 kHz. The default mode of operation of the codec is 16 bit Receive Gain Adjust Mode. In this mode, in every 8 kHz cycle, 16 bits of data is clocked into the codec. The first 13 bits are PCM audio data, the last 3 bits are volume data. Of the last three bits, 000 equates to maximum volume (ATS589=7), 111 equates to minimum volume (Ats589=0).At maximum volume, the output signal matches the amplitude of the input signal at the other end of the Bluetooth link. It is more appropriate to think of this feature as being an attenuation control.The clock rate used for sampling is 250kHz (4µs). 16 clock cycles takes 64µs. 8kHz equates to 125µs.The same timing is used for all packet types in both SCO and eSCO modes.5.Frequency Response5.1 Codec Frequency ResponseThe codec frequency response can be measured by connecting PCM_IN from the codec to PCM_OUT to the codec (PCM_OUT from J1, the 10 way connector has to be disconnected). A 1kΩ pull down resistor is needed on PCM_OUT to ensure maximum volume setting.The following graph shows the measured frequency response. For this test, R32, the side-tone resistor was removed to prevent audio feedback.A 1V peak to peak sine wave was injected into the microphone circuit and its amplitude measured at TP5, A0, the input to the codec. The output from the codec was measured on TP6, PA0+.The chart below shows the codec frequency response with the High Pass Filter Enable (HB – Pin 16) pin set high and set low.As can be seen from the chart, the codec frequency response is flat between 300 and 3,300 Hz. With the high pass filter on, the 3dB points are at 150Hz and 3,600 Hz respectively. With the high pass filter off, the 3dB point goes down to approximately 15Hz.5.2 Bluetooth Link Frequency ResponseThe Codec 13bit linear data is coded within the Bluetooth chip using CVSD (Continuous Variable Slope Decode) encoding for transport over the Bluetooth link. CVSD is essentially a form of Adaptive Differential PCM (ADPCM) and is well suited for voice transmission. It is forgiving of individual bit corruption as each bit only implements an up or a down shift relative to the previous level (corruption of the MSB of a 13 bit sample would create a much larger error term than is possible with ADPCM). A draw back of ADPCM is that it cannot track large delta changes in signal quickly enough. For voice, this does not present a problem.The chart below shows the frequency response of the Bluetooth link at different levels of input sine wave.As can be seen, the frequency response can only be considered to be flat when the input voltage level is less than a 0.3V peak to peak sine wave.6.Circuit DescriptionThis section describes the individual parts of the circuit and give design information aboutthe components, to allow you to adapt the circuitry of the codec board for your own implementation.6.1 Audio AmplifierThe Winbond codec is capable of driving a 32Ω load directly if the gain of the output amplifier is reduced by a factor of 4. This is done by Setting R1 to 39kΩ.Of the stereo headsets tested, it was found that 32Ω was a common impedance for each earpiece. For a stereo headset where two speakers are being driven in parallel this would be equivalent to driving a 16Ω load. This is out of the codec’s specification so a small headphone amplifier, U3, has been used on the evaluation board. This is not required if the impedance of the earpiece is equal or greater than 32Ω.The large 100 μF decoupling capacitors have been used so that the codec could be tested in its “high pass filter mode disabled” configuration. If you do not require a frequency response to go down below 300 Hz, then these capacitors can be reduced to small values. The main design consideration is the impedance should not be significant compared to the impedance of the headphone selected at frequencies of interest.E.g. if using a 32Ω headphone and expecting a 3dB point at 300 Hz, then the decoupling capacitor impedance could be 32Ω at 300Hz i.e. 10 μF. This requires a much smaller footprint than the 100μF used in the reference design.6.2 Driving the Headset Directly from the CodecThis will achieve the most cost effective design but care must be taken to ensure that the 32Ω specification of load is met by selecting an appropriate headset.Remove R10, R13 and R12. Fit R11, R9, R38 as zero ohm links. Fit 39kΩ in place of R1 to reduce the gain by 4.In-house testing showed that with a 32Ω load and with R1 set to 39kΩ, that there was some distortion at zero cross-over but that it was not easily perceptible.Even though the output signal level had been reduced by a factor of 4, on the headsets tested, the volume levels sounded loud enough for most applications. It is important to check this with the target headset for your application.6.3 Microphone CircuitThe microphone circuit is designed for an electret microphone (which is commonly used in PC applications). Typically this would be powered by 5V via a 2.2kΩ series resistor. In the reference design, it is powered by 3.3V to ensure a clean supply regardless of the power supply used to power the Dev kit. This reduces the sensitivity of the microphone - you should test your application with the microphone and voltage you intend to use in order to determine your component values.The gain of the microphone is set by R22 and R24, with gain being equal to R22/R24. The current values are 62K and 3.9K, giving a gain of approximately 16. When changing to a different gain, R27 and R25 should be set to the new values as well. This ensures that the load seen by common mode noise on the microphone is identical and prevents it from being amplified.R31 is a no fit resistor. It’s purpose is to facilitate test modes where a user wants to loop audio output directly back to the audio input to conduct an over the air audio test.6.4 SidetoneWhen we talk, we hear our own voice, which is part of normal speech perception. If our ears are covered by headphones, we do not hear our voice, which is perceived as abnormal. (Try covering your ears while talking to notice the difference).To compensate for the loss in feedback to the ear when it is covered with a headphone, most telephony systems inject some of the microphone signal back into the audio output path so that the person perceives their own speech as normal. This feature is commonly referred to as sidetone.Variable resistor VR2 allows you to control the amount of sidetone that is fed back to the audio output so that the user perceives their speech as normal.If the headset design does not totally cover the ear, then the sideband circuitry can be omitted.6.5 Power DownFor battery powered audio applications, the power down feature of the codec allows you to turn it off and save power when it is not being used. This feature can be tested by fitting R7 with a 0Ωlink and controlling the PUI input of the codec via MPIO_5.For AT commands, MPIO_5 translates to GPIO 7.The put GPIO 7 into output mode, use “ats610=$040”To turn the codec on, use “ats627=1”To turn the codec off, use “ats627=0”6.6 Alternative PCM_CLKSome applications require that the PCM Clock is driven by external circuitry. This requires the PCM Interface provided by the BISM to be put in Slave mode and a clock is supplied by the external circuitry on MPIO_7.Contact Ezurio for further details if this is a requirement.6.7 SwitchesThe switches S1, S2 and S3 have no defined function. They are there to assist you to prototype your audio application. e.g. If your application requires a button to be pressed for the user to answer an incoming connection, you can prototype that function using one of the switches provided.ATS620 allows you to read the status of the GPIO ports.No switches pressed: ATS620? => $0028S1 pressed (GPIO 9) ATS620? => $0128S2 pressed (GPIO 7) ATS620? => $0068S3 pressed (GPIO 8) ATS620? => $00A86.8 High Pass Filter EnableThe W681360 can have its High Pass filter enabled or disabled, depending on the state of the HB pin (Pin 16). This is pulled high or low by R3 or R4 (Default). See section 5.1 for more details.6.9 GPIO to MPIO MappingAT commands use GPIO numbers to represent I/O lines. These GPIO numbers map to physical signals drawn on the schematics as MPIO lines. Some of the GPIO/MPIO lines are used when providing a full RS232 interface.The following tables gives the mapping between GPIO, MPIO and RS232 signals.DCD MPIO_3RI MPIO_2DTR MPIO_9DSR MPIO_8GPIO_1 MPIO_0GPIO_2 MPIO_1GPIO_3 MPIO_9GPIO_4 MPIO_10GPIO_5 MPIO_11GPIO_6 MPIO_4GPIO_7 MPIO_5GPIO_8 MPIO_6GPIO_9 MPIO_7Note: For the BISM PA (Class 1 design), MPIO_0 and MPIO_1 are used to control the RF switch so are not available to the AT Command Set.7.

When properly calibrated, a single pressure range can be used in many different pressure re-quirements. Selecting a transmitter with a high pressure range may come close to providing a “one transmitter fits all” possibility. To correctly apply a pressure transmitter for use over a wide range of pressures, it is neces-sary to have an understanding of sensor reranging and accuracy.Reranging of a pressure transmitter is the process of redefining the minimum and maximum measurement points of the device. The difference between these two points is referred to as the Calibrated Span of the transmitter. The ABB Totalflow Pressure Transmitter can be reranged or calibrated from 100% of URL (Upper Range Limit) of the pressure sensor to a minimum of 20% of the URL and any percentage between 20% and 100% URL. Accuracy of a pressure transmitter is determined by comparing its pressure output value to a known pressure standard. Totalflow includes in its pressure transmitter accuracy the combined effects of the sensor linearity, hysteresis and repeatability at reference conditions. The accuracy remains constant across the allowed“rerange” limits i.e. calibrated span. The Totalflow pressure transmitter has a stated accuracy of +/- 0.05% of Calibrated Span for the X Series flow computer and +/- 0.075% of Calibrated Span for the microFLO flow com-puter.The following example should give an understanding to the Rerange limits and Accuracy of a Totalflow pressure sensor. Example: Rerange : the Equation to use is: URL x % Range Limit 1,000 psia Upper Range Limit pressure sensor100% Range equals 1,000 psia which is 1000 x 100% 20% Range equals 200 psia which is 1000 x 20%Accuracy : the Equation to use is: URL x % Range Limit x % Accuracy1,000 psia Upper Range Limit pressure sensor with 0.05% Accuracy Ranged at 100%:Accuracy equals +/- 0.5 psia which is 1000 x 100% x 0.05%1,000 psia Upper Range Limit pressure sensor with 0.05% Accuracy Ranged at 20%:Accuracy equals +/- 0.1 psia which is 1000 x 20% x 0.05%What this means is that a 1,000 psia pressure sensor can be calibrated from a maximum of 0 to 1,000 psia and a minimum of 0 to 200 psia and any pressure calibrated span between 200 and 1,000 psia. Calculated accu-racy for this sensor would be +/- 0.1 to +/- 0.5 psia. One pressure sensor may fit many if not all of your pressure requirements.controls on flow rate, but switches to the override controller (pressure) when certain conditions are met. The ABB Totalflow X Series of Flow Computers or Remote Controllers can implement the standard Valve Control Application . The Valve Controller has the option to be used with a Digital Valve Actuator or an Analog Valve Actuator. The Application positions a control valve to maintain control of either differential pressure (DP), static pressure (SP) or flow rate (FR). Additionally, an Override functionIn an upset condition, it is some-times important to control a flow rate, yet switch to pressure control. For example, a well might be set up to primarily control flow rate, but revert to pressure control if the line pressure increases beyond an acceptable limit. It might also be that the well needs to revert to pressure control, if the pressure drops too low, keeping the gas from flowing into the gatheringsystem. We sometimes refer to the flow rate controller as the primary controller and the pressure control-ler as the override control. That is, in this case, the system primarilycan be selected which will limit any secondary parameter to a user defined limit. Override, for exam-ple, may be used to maintain the well’s production rate or to main-tain the pressure entering the gathering system, or to shut-in the well or to bring-on the well, based on pressure. For example, when the override pressure sensor is installed downstream of the control valve, the well’s on/off state can be coordinated with a compressor on-off state. This allows the well to automatically shut-in and come-on, based on the status of the com-pressor for that well.Good valve control can provide Consistent Production and a Safe Environment. Proper valve control promotes a steady production of the well, insuring more flow time, and allows for an override of pres-sure or flow rate to prevent anunsafe condition in the gas system.

Training Manual范本在现代职场中,培训是获得成功的必要条件之一。
通过实施培训,员工可以获得新技能、知识和经验,从而提高其绩效和创造力。
此外,公司也可以更好地满足员工的需求,从而改善员工满意度和减少员工离职率。
因此,编写一份完善的培训手册对于公司的成功至关重要。
下面将介绍一份培训手册的范本,以帮助初学者更好地编写和制作培训手册。
一、培训手册的制作方式在制作培训手册之前,必须先定义它应该包括哪些内容。
最好创建一个详细的大纲,以便在创建相应章节时有一个清晰的思路。
此外,在手册中使用图表和图像可以帮助读者更好地理解概念。
还有一个很重要的问题是要确定使用的媒介类型。
根据受众不同,一份培训手册可以是纯粹的文字文本、PDF格式,或者是具有互动性的电子学习模块。
了解公司的需求和员工的偏好将对选择适当的媒介类型至关重要。
二、培训手册应包含哪些内容1. 介绍每一份培训手册应该以介绍和目的的声明为开端。
该章节不仅可以钦定培训手册的目的和内容,还可以使读者了解培训的目的和相关的商务目标。
2. 具体的培训课程项目实施的下一步是确立具体的培训目标。
除非制定清晰的培训计划,否则难以评估培训的效果。
因此,在手册的第二章,应定义详细的培训内容,以及其相应的时间表。
3. 课程的目标一份完善的培训手册应阐明课程的目标。
明确目标不仅可以帮助员工了解其培训的目的,还可以帮助业务领导评估培训的实际效果。
4. 针对特定群体的培训方式培训的受众并不总是相同的,因此,对于每个不同的工作角色和技能等级,应制定不同的学习模块。
这些模块可以包括视频、在线资源和互动型试题等。
5. 测评和反馈一个有效率的培训程序应该提供测验考核机会,以便检查学员是否真正理解了所学的知识。
还需要提供反馈机会,以便帮助学生在下一步的学习中改进他们的表现。
6. 培训的时间表和执行计划为了确保培训的顺利进行,同时保证ERT时效,业务定期推动培训进度,并提供具体的时间表和执行计划。
