PLC CPX4 and Audio

HughNZ

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?

Regards,

Hugh

    Description
    Who do we contact at Renesas to obtain the SDK for the CPX3 and CPX4 PLC chips so we can write our own code to run on the RX651 MPU on the Renesas CPX3 and CPX4 kits?

    Can the CPX4 be used for Voice over PLC applications, as per the CPX3?

    Is the source code for the Renesas Voice over PLC Sample Application and or the Renesas PLC Voice Communicator application available?

    Are the schematics and PCB layouts shown in the R30AN0393EJ0100 CPX4 DC-PLC Evaluation Kit M01D1 – RTK0EE0009D01001BJ SCH, BOM, PCB Layout document available as Altium Designer or other electronic format?

    Note we have been attempting to obtain the above information from Renesas Singapore for several weeks.

    Regards,

    Hugh
