Hello, the Relay Expansion Module I got is different than the one pictured in the Relay Expansion Manual
V1.2.1. Again Roberto I'm lost. You have been so helpful. Thanks

You have a second gen module, but there is no need to change anything on it, unless you have more than 1. The dip switch inside is still the same.

Thanks! Do I still have to do this?

Setting up your Reef Angel Head Unit
1. Your Reef Angel Head unit needs to be setup to be able to communicate with any expansion modules.
2. You need to place the provided jumpers to the SDA and SCL pins

The new units are coming already with them pre-installed.

So cable wise, comm cable from expansion module to expansion relay. and Mini usb from expansion module to usb on primary relay box. Just 2 cables required? I have 1 cable that was included that I don't know what it is for. Its a usb to 3 pin.

Man you have to be a busy person. You handle all these questions yourself? You do an excellent job. I definately will pass praise when I do my RA thread on Reef Central.
