- Specify a unique board ID (COMM address) for each of the multiple devices.

 

 

- Check the baud rate if it matches with the PC application.

For RS-422 communications, install a termination resistor at the point where the

 

system is connected to the RS-422/RS-232 converter of the PC.

 

 

(Install a 120Ω termination resistor between the RX+ and the RX- terminals on the

 

device side, another 120Ω between the TX+ and the TX- terminals; the same

 

should be done to the converter. If you are not sure about the wiring, contact the

 

customer service for your help.)

 

 

 

 

 

 

If the problem persists after you followed the instructions above, this may be caused

 

by the defective of an internal circuit. Contact the customer service.

 

¼If no communication is established after you tried to do so with multiple devices, pick just one device and connect it to the RS-232/RS-422 converter, and to the PC. Then, check if there is any communication available.
