Has anybody used the CPX4 for voice audio? We are looking at using the CPX4 in a fire panel phone system with up to 20 phones on a 1km loop.
We purchased 2 Renesas CPX4 DC kits for testing with various cable types, and seems to operate over 2km of fire rated cable in CPX mode with out any problems.
We purchased 2 Renesas CPX3 + Audio kits to test Audio over PLC and seems to work well.
There doesn't seem to be any demo software available from Renesas for sending audio with the CPX4.
We are attempting to get the SDK from Renesas for the CPX3 and CPX4 so we can write our own code to run on the RX651 MPU on the kits, and also the source code for the audio demo software (if available) so we can modify it. So far we have hand no responses from Renesas Singapore. Does anybody have any suggestions on who to contact at Renesas regarding software support for PLC?
