I'm looking for opinions from fellow readers on what modbus modems are used to interface with DCS.
Currently all my Mark V (2GT and 1ST) are connected to DCS via serial modbus from HMI. Modbus modems are connected at each end (HMI and DCS) for the connection- From HMI to modem via DB9 port; from HMI modem to DCS modem via RS485; from DCS modem to DCS module via DB9 port.
Currently the modem which I'm using (Develcon DS511A) which has been working well but now been obsolete. I'm looking for any similar modems which can be used to replace them. Any advice on what modems are used by other readers are greatly appreciated.
