I have an old multi-zone amplifier that used to be controlled via up to eight LCD touchpads throughout the house.
These touchpads were connected to the amplifier by CAT5 with RJ45s at each end. I assume it's based on RS422.
I would now like to use Arduino(s) or Rasp Pi(s) - instead of the touchpads - so I can use IFTT or other and control the amp via mobile device and/or web browser.
How can I
I'm also trying to work out if I would need a MC in place of each of the eight touchpads, or would there be a way to stack shields so a single MC could control 2 or more (or all) of the zones?
Any help or pointers would be awesome.
Thanks in advance!

How can I
- reverse-engineer the communication protocol so I can emulate it
- connect the microcontroller to the RJ45 ports on the amp, and send the emulated commands
