7. SERIAL AND USB

7.3 Standard serial port protocol

7.2.4  TYPE-2 INTERFACE

: Discontinual RS-232C Interface

    SHARP  ER-AXXX,  ER-A450T,  New  SANYO  ECRs  using  RS-

232,TOLEDO 3213 etc.

1) PROTOCOL

        POS/ECR                      SCALE( DSW-100 )

        Command <W>  ------------>    

                                        <------------  Response

                                             <STX> XXXXX <CR> : weight data (kg,lb, oz)

                                            Error message : <STX><status byte><CR>

2) REMAKE

  

W :   

57H (ASCII code)

              STX :   02H (ASCII code)

                CR :   ODH (ASCII code)

3) STATUS BYTE  

Bit 4 =1  Scale at Zero ,       

Bit 4 = 0  Not at Zero

Bit 2 =1  Weight is Minus,      

Bit 2 = 0  Weight is not Minus

Bit 1 =1  Over Capacity,    

Bit 1 = 0  Not Over Capacity

Bit 0 =1  Scale in Motion,      

Bit 0 = 0  Stable

4) Serial Communication   9600 Baud rate, 7 Data bit, Even Parity, 

1 Stop bit
