I am using a Raven-X to communicate to multiple cell modems to communicate with devices using serial MODBUS. I am attempting to upgrade that modem to a RV50. I have matched settings and even tried to create and apply a template from the old to the new. The modem appears to send the MODBUS message and the field devices reply but it is not being read or utilized by the host device. Additionally, I have changed the destination address in the remote units to match the new IP.
Suggestions as to what could be wrong and what to change or try would be appreciated.
