Modbus Wiring

2-Wire RS-485


+ connects to + and – connects to -
4-Wire RS-485


+’s and –’s are swapped
TX+ > RX+, TX- > RX-, etc.
Modbus Configuration

Modbus Address, Parity, Baud Rate
Incorrect Sepam Port selection

Sepam 80 has dual comm and
remote module ports
ION Master Connections

To communicate to an ION meter
there are two communication port
settings that need to be made.


Comm port on the meter needs to be

I/O module is absent
MCS025 (Sync-Check) is not available
Wrench 10

