Notes:
(i) RS485 can only be used with software release Ver. 4.02 onwards.
(ii) RS485 Data Hi-way is not compatible with RS422 Data Hi-way devices
such as IN-2000-AI, IN-2000-AO, IN-2000-DI, IN-2000-DO, FP21,
SR25, etc. Use a 2100-4S to interface an RS485 Data Hi-way to an
existing RS422 Data Hi-way
RS232:
2100-IS convertor is not required to connect the 2100-232
directly to a PC. Use the RS232 kit to connect the 2100-232
directly to a PC. The PC requires one RS232 port per 2100.
RS485:
If the outstation is using RS485, it cannot be connected to the same
data hi-way as an outstations using RS422. In the ‘programming’
box, set the ‘TX delay’ box to 20. Set the Dip switches on the
2100-IS and the jumpers on the 2100 for RS485 operation.
