Relay Expansion

[Govertical19]

Ok,

So I am setting up the expansion relay I have had for months. Just want to make sure I have it correct..

Open Head unit and put the jumpers on SDA & SCL. there is no jumper on rst?

Since I only have one exp I leave all dip switches to off.

Connect comm cable to module and new relay.

Connect usb cable from 1st relay to expansion module.

Then setup code.

All correct?

Thanks!

Yeap, except you need all three jumpers. RST also needs one.
If you don't have them and can't find any laying around, please send me a PM

This is a requirement? I didn't do anything with jumpers and my exp relay and relay box are working fine.

New head units are coming with the jumpers pre-installed already.
You must have a newer model.

Yeah just got it last week.
