 RS232/RS485 SERIAL OUTPUT (OPTION)

1) STANDARD : EIA-RS232/RS485 output
2) STREAM FROMAT
Data bit = 7
Parity bit = 1 (even)
Stop bit = 1
Code = ASCII code
Baud rate = 2400, 4800, 9600, 19200
Delimiter = CR/LF
3) RS232/RS485 MODE
a) Command mode: After receiving the command word from
RS232/RS485 port, the indicator will carry out
the appropriate action, those command valid
only for RS232/RS485 port.
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.
b) Continuous mode: The data will be transferred constantly without any
input command to the RS232/RS485 port.

Hi/Lo COMPARATOR OUTPUT(OPTION)
1) Hi/Lo output : HH, Hi, Lo or LL
2) Max. capacity : 80VDC, 300mA
2-6 BCD OUTPUT(OPTION)
1) BCD output : Parallel BCD output
2) BCD output level : TTL or open collector
2-7 ANALOG OUTPUT(OPTION)
1) Analog output mode : 0~5V/0~20mA/4~20mA
2) The excitation current will be reduced to 120mA if the 0~20mA/4~20mA output board is used.
2-8 INPUT(BUILT-IN)
1) Input : IN1, IN2 or IN3
2) Input mode : Passive switch
3) Input contact time : 30 ms
