View Full Version : Multiple Grinch Controllers with Ren C

I understand how a single controller works with vixen, but when you start daisy chaining the controllers together with RS485, how do you tell the first controller it should only handle channels 1-64 and the second controller 65 - 128?

I don't see any configuration that I can change on the hardware.

You set this up in Vixen. If you have 2 Ren-C/Grinch Controllers on COMM 1 you put channels 1-128 on COMM 1. The firmware on the PIC is set up so it will only address 64 channels and if the channel count is out of the range of the first chip say turning on channel 75 it the first Ren-C will pass the information on down the line.

Ok, thanks.

I've only used GE Wireless receivers on a RS485 bus that required us to program an ID number for each receiver. This way is much easier.
