The data and commands required to transfer data with the host controller (microcontroller) are set via this serial interface.When the host controller transmits data to the µPD6708 via the serial interface, signals are output from the BUS pins (BUS+ and BUS–). Data received from the BUS pins can be read by the host controller via the serial interface.572.2 IEBus Communication Protocol An overview of the IEBus is as follows.•Communication system: Half-duplex asynchronous communication •Multi-master systemAll the units connected to the IEBus can transfer data to the other units.•Broadcast communication function (communication between one unit and multiple units)Group broadcast communication:Broadcast communication with group units General broadcast communication:Broadcast communication with all units.•Three modes with different transfer speeds selectable.f X = 12 MHzf X = 12.58 MHzMaximum Number of Transfer Bytes(bytes/frame)Mode 0Approx. 3.9 Kbps Approx. 4.1 Kbps 16Mode 1Approx. 17 Kbps Approx. 18 Kbps 32Mode 2Approx. 26 KbpsApprox. 27 Kbps128•Access control: CSMA/CD (Carrier Sense Multiple Access with Collision Detection)The priority order for bus occupancy is as follows.<1>Broadcast communication takes precedence over ordinary communication (i. e., communication between one unit and another).<2>The lowest master address has the highest priority.•Communication scale Number of units:MAX. 50Cable length:MAX. 150 m (with twisted-pair cable <Resistance: 0.1 Ω/m or less>)Load capacity:MAX. 8000 pF <between BUS– and BUS+>, f X = 12 MHz MAX. 7100 pF <between BUS– and BUS+>, f X = 12.58 MHzTerminating resistor:120 Ω582.2.1 Bus mastership determination (arbitration)When a unit connected to the IEBus controls another unit, it performs an operation to occupy the bus. This operationis called arbitration.Arbitration is to select one unit, and if several units begin to transmit data simultaneously, gives permission to occupy the bus to that one unit.So that one unit is granted the permission to occupy the bus as a result of the arbitration, the following priority conditions are determined.RemarkThe units not given permission through arbitration are automatically allowed to get into retransfer mode (number of retransfer times for the µPD6708: 3).(1)Priority according to type of communicationBroadcast communication (between a single and multiple units) takes precedence over ordinary communication (between single units).(2)Priority according to master addressIf the communication devices are of the same type, the unit with the lowest master address has the highest priority.ExampleThe master address comprises 12 bits, and unit 000H has the highest priority while unit FFFH has the lowest priority.2.2.2 Communication modesThe IEBus is provided with three communication modes with different transfer speeds. The transfer speed and maximum number of transfer bytes in a single communication frame in each communication mode are shown in Table 2-1.Table 2-1. Transfer Speed and Maximum Number of Transfer Bytes in Each Communication ModeCommunication ModeMaximum Number of Transfer Bytes (bytes/frame)Actual Transfer Speed Note 1 (Kbps)f X = 12 MHz Note 2f X = 12.58 MHz Note 2016Approx. 3.9Approx. 4.1132Approx. 17Approx. 182128Approx. 26Approx. 27Notes 1.Actual transfer speed when the maximum number of bytes is transferred2.Oscillation frequency when the µPD6708 is usedCautions 1. A communication mode is selected for each unit connected to the IEBus before communication isperformed. If the communication mode of the master unit is not the same as that of the unit withwhich the master unit is to communicate (slave unit), communication cannot be performed correctly.2.If the oscillation frequency of one unit is fx = 12 MHz and that of the other unit is fx = 12.58 MHz,communication cannot be performed correctly even if the communication mode is the same. Make sure that the oscillation frequencies of the two units to communicate are the same.592.2.3 Communication addressWith the IEBus, a 12-bit communication address is assigned to each unit. The communication address is made up as follows.Higher 4 bits:Group number (number which identifies the group to which the unit belongs)Lower 4 bits:Unit number (number which identifies a unit within a group)2.2.4 Broadcast communicationIn ordinary communication, there is only one master unit and one slave unit, and transmission or reception is performed on an one-to-one basis. In broadcast communication, however, there are a number of slave units and the master unit performs transmission with these slave units. Because there are several slave units, no acknowledge signals is returned from the slave units during communication.Whether broadcast communication or ordinary communication is performed is specified by the broadcast bit (for the broadcast bit, see 2.3 (1) <2> “Broadcast bit”).There are two kinds of broadcast communication, as follows.(1) Group broadcast communicationBroadcast communication is performed to the units in a group whose group numbers are the same as that specified by the higher 4 bits of the communication address.(2) General broadcast communicationBroadcast communication is performed to all units irrespective of their group numbers.Group broadcast communication or general broadcast communication is identified by the value of a salve address (for the slave address, see 2.3 (3) “Slave address field”).5102.3 Transfer ProtocolThe IEBus transfer signal format is shown in Figure 2-1.Data is transferred as a series of signals called a communication frame. The number of data that can be transferred in one communication frame and the transfer speed differ depending on the communication mode.Figure 2-1. Transfer Signal FormatP:Parity bit (1 bit)A:Acknowledge bit (1 bit)When A = 0: ACK When A = 1: NAK N:Number of data bytes RemarkIn broadcast communication, the value of the acknowledge bit is ignored.(1)HeaderA header comprises a start bit and a broadcast bit, as described below.<1>Start bitThe start bit is a signal which tells the other units that data transmission will start.The unit which is about to start transmitting data will output the low signal (the start bit) for a specified time, and then outputs the broadcast bit.If another unit is already outputting a start bit before one unit outputs a start bit, the unit will not output the start bit.It will wait until the another unit completely outputs the start bit, and then outputs the broadcast bit.The units other than the one that has started transmission detect this start bit and enters the reception state.<2>Broadcast bitThe broadcast bit distinguishes between broadcast communication and ordinary communication.When this bit is ‘0’, it indicates broadcast communication; when it is ‘1’, it indicates ordinary communication. There are two types of broadcast communication: group broadcast and general broadcast. These types are identified by the value of the slave address (for the slave address, see (3) “Slave address field”).In broadcast communication, there are a number of slave units. Therefore, the acknowledge bit is not returned in the fields described in (2) below and onward.If two or more units start to transmit a communication frame simultaneously, broadcast communication takes precedence over ordinary communication, and wins in the arbitration.5Field Name Number of BitsTransfer TimeMode 0Mode 1Mode 2Header Master Address Field Slave AddressField Control Field MessageLength Field Data Field112111211411811811811Start Bit Broad-cast Bit Master AddressP Slave Address PA Control BitPA Message Length BitPADataBitPAData BitPAApprox. 7330 s µApprox. 2090 s µApprox. 1590 sµApprox. 1590× N s µApprox. 410× N s µApprox. 300× N sµ(f x = at 12 MHz)(2)Master address field5 The master address field is used to transmit the unit address of the master unit (master address) to the other units.The master address field consists of master address bits and a parity bit.The master address comprises 12 bits and is output from the MSB.If two or more units start transmitting the broadcast bit of the same value simultaneously, the arbitration decision is madeby the master address field.The master address field compares the data the master has output with the data on the bus each time the master transmits1 bit of data. If the master address output by the master unit is different from the data on the bus, the master unit assumesthat it has lost in arbitration, stops transmission, and enters the reception state.Because the IEBus has a wired-AND configuration, the unit having the lowest master address of the units participatingin the arbitration (arbitration masters) wins in the arbitration. Ultimately, only one unit remains in the transmission stateas the master unit after outputting a 12-bit master address.This master unit then outputs a parity bit Note, makes the other units confirm the master address, and then outputs the slave address field.Note Even parity is used. When the number of the bits that are ‘1’ in the master address is odd, the parity bit is ‘1’.(3)Slave address fieldThe slave address field is used to transmit the address (slave address) of a unit (slave unit) with which the master wishesto communicate.The slave address field consists of slave address bits, a parity bit, and an acknowledge bit.The slave address comprises 12 bits and is output from the MSB. After the 12-bit slave address is transmitted, the paritybit is output to prevent the slave address from being received incorrectly. Next, the master unit looks for the acknowledge signal (bit) from the slave unit to confirm that the slave unit exists on the bus. When the master unit detects the acknowledge signal, it starts outputting the control field. In the case of broadcast communication, however, the master unit outputs the control field without waiting for the acknowledge bit.A slave unit outputs the acknowledge signal if it has detected that its slave address coincides with that selected by the master and that the parities of both the master and slave addresses are even. If the parity is odd, the slave unit assumesthat the master or slave address has not been correctly received, and does not output the acknowledge signal. In this case,the master unit enters the standby (monitor) state and communication ceases.In the case of broadcast communication, the slave address is used to distinguish between group broadcast and general broadcast as follows:Slave address = FFFH:General broadcast communicationSlave address ≠ FFFH:Group broadcast communicationRemark In the case of group broadcast communication, the group number is the value of higher 4 bits of the slave address.(4)Control fieldThe control field indicates the type of data and the transfer direction of the subsequent data field.5The control field consists of 4 control bits, a parity bit, and an acknowledge bit.The control bits are output from the MSB.A parity bit is output after the control bits. When the parity is even and the slave can execute the function requestedby the master unit, the slave unit outputs an acknowledge signal, and then outputs the next message length field. If the slave unit cannot execute the function requested by the master unit even if the parity is even, or if the parity is odd, the slave unit does not output the acknowledge signal but returns to the standby (monitor) state.After the master unit has confirmed the acknowledge signal, it starts outputting the next message length field.If the master unit is cannot confirm the acknowledge signal, it enters the standby state and stops communication. In the case of broadcast communication, however, the master unit starts outputting the message length field without confirming the acknowledge signal.For the functions of the control bits, see Table 2-3.(5)Message length fieldThe message length field is used to specify the number of communication data bytes.The message length field comprises 8 message length bits, a parity bit and, an acknowledge bit.The message length bits are output from the MSB. The message length bits indicate the number of communication data bytes as shown in Table 2-2.Table 2-2. Meaning of Message Length BitsMessage Length Bits (hex)Number of Transmission Data Bytes01H 1 byte02H 2 bytes::::FFH255 bytes00H256 bytesRemark In the communication mode, if the number of bytes exceeding the maximum number of transfer bytes per frame is set, two or more frames are communicated. In this case, the message length bits indicate the number ofremaining communication data bytes during the second communication and onward.The operation of this field differs depending on whether the master transmits (bit 3 of control bits is 1) or receives (bit3 of control bits is 0) data.<1>When master transmits dataThe message length bits and parity bit are output by the master unit. The slave unit outputs the acknowledge signal and then the next data field if it detects that the parity is even. The slave unit does not output the acknowledge signal in the case of broadcast communication.If the parity is odd, the slave unit assumes that the message length bits have not been received correctly, and returns to the standby (monitor) state without outputting the acknowledge signal. In this case, the master unit also returns to the standby state, and communication ceases.<2>When master receives dataThe message length bits and parity bit are output by the slave unit. The master unit outputs the acknowledge signal if it detects that the parity bit is even.If the parity is odd, the master unit assumes that the message length bits have not been received correctly, and returns to the standby state without outputting the acknowledge signal. In this case, the slave unit also returns to the standby state, and communication ceases.(6)Data fieldThe data field is used to transmit/receive data to/from the slave units.The master unit uses the data field to transmit data to and receive data from the slave units.The data field consists of 8 data bits, a parity bit, and an acknowledge bit.The data bits are output from the MSB.Following the data bits, the parity bit and acknowledge bit are output from the master unit and the slave unit, respectively.Broadcast communication is performed when only the master unit transmits data. At this time, the acknowledge signal is ignored.The operation differs depending on whether the master performs transmission or reception, as follows.<1>When master transmits dataWhen the master unit writes data to the slave unit, the master unit transmits data bits and a parity bit to the slave unit.The slave unit receives the data bits and parity bit. If the parity is even and the receive buffer is empty, the slave unit outputs the acknowledge signal. If the parity is odd and the receive buffer is not empty, the slave unit denies acknowledgment of the corresponding data and does not output the acknowledge signal.If no acknowledge signal is output from the slave unit, the master unit transmits the same data again. The master unit continues this operation until it detects the acknowledge signal from the slave unit or the data reaches the maximum number of transfer bytes.If the parity is even and the acknowledge signal has been output from the slave unit, and if the master unit has more data to transmit and the maximum number of transfer bytes is not exceeded, the master unit will transmit the next data.In the case of broadcast communication, the slave unit does not output the acknowledge signal, and the master unit transfers data on a byte-by-byte basis.<2> When master receives dataWhen the master unit reads data from the slave unit, the master unit outputs synchronization signals corresponding to all the read bits.The slave unit outputs the contents of the data and parity bits onto the bus in accordance with the synchronization signals from the master unit.The master unit reads the data and parity bit output by the slave unit, and checks the parity.If the parity is odd or the receive buffer is not empty, the master unit denies acknowledgement of that data and does not output the acknowledge signal. If the data is within the maximum number of transfer bytes that can be transmitted in one frame, the master unit repeatedly reads the same data.If the parity is even and the receive buffer is empty, the master unit acknowledges the data and transmits back theacknowledge signal. If the data is within the maximum number of bytes that can be transmitted in one frame, the master unit reads the next data.5 5(7)Parity bitsParity bits are used to check that there is no error in the transfer data.A parity bit is added to the master address bits, slave address bits, control bits, message length bits, and data bits.Even parity is used. If the number of the bits that are ‘1’ bits in data is odd, the parity bit is ‘1’, and if the number of the bits that are ‘1’ bits is even, the parity bit is ‘0’.(8)Acknowledge bitsIn ordinary communication (between two units), an acknowledge bit is added to the following places to confirm that data has been acknowledged correctly.•At the end of the slave address field.•At the end of the control field.•At the end of the message length field.•At the end of a data field.The definition of the acknowledge bit is as follows.•‘0’: Indicates that transfer data has been acknowledged (ACK).•‘1’: Indicates that transfer data has not been acknowledged (NAK).Note that the value of the acknowledge bit is ignored in broadcast communication.<1>Acknowledge bit at the end of the slave fieldWhen any of the following conditions is met, the acknowledge bit at the end of the slave field is NAK, and communication is discontinued.•If the parity of the master address bits or slave address bits is incorrect.•If a timing error (error in bit format) occurs.•If the slave unit does not exist.<2>Acknowledge bit at the end of the control fieldWhen any of the following conditions is met, the acknowledge bit at the end of the control field is NAK, and communication is discontinued.•If the parity of the control bits is incorrect.5•If bit 3 of the control bits is ‘1’ (write operation) when the slave receive buffer Note is not empty.•If the control bits indicate read operation (3H or 7H) when the slave transmit buffer Note is empty.•If 3H, 6H, 7H, AH, BH, EH, or FH of control bits is requested from a unit other than the unit which set the lock whena lock has been set.•If the control bits indicate lock address read (4H) when a lock has not been set.•If a timing error occurs.•If the control bits are undefined.Note See 2.4 (1) “Reading slave status (SSR) (control bit: 0H, 6H)”.<3>Acknowledge bit at the end of a message length fieldWhen either of the following conditions is met, the acknowledge bit at the end of the message length field is NAK, and communication is discontinued.•If the parity of the message length bits is incorrect.•If a timing error occurs.<4>Acknowledge bit at the end of a data fieldWhen any of the following conditions is met, the acknowledge bit at the end of a data field is NAK, and communication is discontinued.•If the parity of the data bits is incorrect Note.•If a timing error occurred in or after the previous acknowledge bit transmission.•If the receive buffer is full and cannot accept any more data Note.Note In this case, if the number of transfer bytes is within the maximum number of bytes which can be transmitted, the transmitting side re-executes transmission of that data field.。

如何调节条码扫描枪的声音大小?如何调节条码扫描枪的声音大小?条码扫描枪蜂鸣器的声音大小都是出厂默认的,可能有些客户会觉得声音太大或者太小,其实我们也可以设定声音大小。

条码扫描枪蜂鸣器的声音大小的设置可以在用户手册中找到。

但大多数条码扫描枪只有英文手册,所以对于英文较差的用户来说,可能就不怎么会设置了,扫描网小编特写此文,希望能帮助这些用户找到快速设置声音大小的方法。

由于条码扫描枪品牌和型号繁多,一下子也不能一一列出,所以下面以分别以扫描枪中英文手册为例,您也可以参考以下方法,在您的说明书中找到对应设置条码,扫描一下即可。

1 ) 以摩托罗拉条码扫描枪DS6708为例,摩托罗拉条码扫描枪手册都是英文的,我们首先在目录中找到关于蜂鸣器音量设置【Beeper Volume】的章节5-9,如下图。

点击一下目录中的【Beeper Volume】，将自动跳转到该页面，然后你就会看到调节音量大小的设置条码，分别为低音量、中音量和高音量三种选择。

您可以根据自己的需求来选择其中一种，然后扫描一下该条码即可。

2) 以民德MD2系列扫描枪为例，民德条码扫描前边个手册有中英文两个版本，我们在中文版手册目录中并没有看到蜂鸣器音量的相关文字，但是可以找到与蜂鸣器相关的章节【LED指示灯和其他】，我们找到这个页面就可以看到，里面有蜂鸣器音量大小的设置介绍，如下图：然后按照下面顺序依次扫描对应条码：a）扫描【开始设置】，b）扫描左边的【蜂鸣器音量】条码c）在手册最后一页，扫描你选择的音量右边对于的数字条码。

如“低音对应的是00，中音是01，高音是02*”d）扫描【结束设置】以上就是条码扫描枪声音大小调节的方法，其他品牌的条码扫描枪的声音大小设置步骤基本类似，您只需要在说明手册上找到蜂鸣器的设置章节，然后按照上面说的设置步骤依次扫描条码即可。
