We have 4 Landys Gyr meters with the attached model numbers.
Three of this model:
One of this model:
They do not have an RS232 card installed (except for the ZMD), so I guess our only option is to use optical for the ZMG?
In this case, can we use two gateways with Modbus RTU output?
Please note that our modbus master has an RS-485 (not RS-232) interface only, will it be compatible with your modbus gateway with an RS232 interface?
With 2 optical gateway you can read 4 meters, but remember optical probe is sold separately and cable of probe is max 3 meters, so gateway has to be placed near the meters.
Modbus rtu will be available on RS485 port of our gateway
