Question no.1 (ask on 05/09/2014) : If I use the COM2 port for RS-485 communication, what is the maximum number of instruments which I can connect?
answered on 05/09/2014 :
It depends on the transmitter-receivers and the protocol used. If low-power transmitter-receivers are used, you can communicate with up to 247 instruments via the Modbus protocol.
If high-power transmitter-receivers are used, you can control up to 32 instruments.
