3. Configuration via RS-485 

 

  The factory default settings for RS-485 communication 

 

Address: 1 

 

Protocol: Modbus/RTU 

 

Baudrate: 9600 

 

Parity: N,8,1 

 

Response Delay (ms): 0 

 

Note 

If there are multiple iSN-101/104 connected to the same RS-485 network, each 

module needs be set with a unique RS-485 address. More than one module having 

the same address will cause communication failure
