3. Serial Communication interface and Scoreboard
(Note : this function is optional)
Serial communication interface
Communication interface uses 5-pin socket (pin) and all the data is ASCII code, and there are 10 bits
in every data group, and the 1st bit is start bit and the 10th bit is stop bit, and there are 8 bits in the
middle and there is no parity bit.
1. Connection mode
CAS DH communication interface uses 9-pin socket (pin). Lead pin is defined as follows: pin 2 is for
TXD (serial communication data line) and pin 5 is for ground wire; shielded cable is recommended to
be used as connection line. See below Figure details.
Communication for scoreboard and RS232
2. Interface parameter
① Signal : RS232C
② Baud rate : 1200/2400/4800/9600
3. Communication method
Method 1 P5=2 continuous transmission
Transmitted data is weight. (gross weight, net weight or tare weight, decided by parameter P4).
Gross weight format is : ww000.000kg or ww000.000lb
Net weight format is : wn000.000kg or wn000.000lb
Tare weight format is : wt000.000kg or wt000.000lb
Note : Above decimal point position is determined by decimal point position setting of the indicator.
