Remote Control Instructions; Rs232 Pinout (9-Pin D-Sub) - G&G JJ-BC Series Operating Instruction

12.3 Remote control instructions

Via the RS232 data interface, the computer can control the balance with subsequent commands.
If the transmit / device setting is 27 (27=1B
the balance by ASCII code:
1BH+70H (ACSII Code p): sending data
1BH+71H (ACSII Code q): calibration function is active
1BH+72H (ACSII Code r): Counting function is active
1BH+73H (ACSII Code s): Weighing unit selection
1BH+74H (ACSII Code t): Taring

12.4 RS232 Pinout (9-pin D-Sub)

DE-9 plug pin-out (9-pin., male), as it is usually
available at DTE
DTE - data terminal equipment (Terminals resp. computer)
DCE - data circuit-terminating equipment (Balance)
Abbreviation Name
RxD Receive Data
TxD Transmit Data Carries data from DTE to DCE. 3
GND Ground
Application Example:
If the setting is C3---2, C4---27 (default setting), the codes shown in VB as following:
MSComm1.Settings = "600,n,8,1"
MSComm1.Output = Chr(&H1B) + Chr(&H70)
'or MSComm1.Output = Chr(27) + Chr(112)
'or MSComm1.Output =Chr(27) +"p"
