2.4 RS232/RS485 SERIAL OUTPUT (2 OPTIONS)
1. Standard : EIA-RS232/RS485 output
2. Stream format : 7 Data bits, 1 stop bit, even parity

b) Data type : ASCII code
c) Delimiter : CR/LF
3. Communication mode
a) Command mode:
-After receiving the command word from the RS232/RS485 port, the indicator will carry
out the appropriate action. Those commands valid only for RS232/RS485 port are.
Command: READ<CR><LF> : request measured data
TARE<CR><LF> : request TARE weight setting
KEY<CR><LF> : key protection ON or OFF
ZERO<CR><LF> : request ZERO value
Example: Read command (READ<CR><LF>) is “52H, 45H, 41H, 44H, 0DH, 0AH”
in ASCII code, numbers in hexadecimal.
b) Continuous mode:
-The data will be transmitted constantly without any input command to the RS232/RS485 port.
