We have recently swapped an existing ion 7550 meter with the same meter. The meter communicated via rs-485 modbus rtu protocol with the c264. the problem is the new meter does not transmit any data to the rtu. whereas if I connect the old meter back into the loop, the meter transmits data instantly. the new meter successfully communicates with a modbus simulator (mdbus). the baud rate, protocol and slave address are the same as the old meter. is there any new configuration we need to do on the rtu side? ...please advise
