Hi all,

is it possible to control the GHL STDL4-4 via simple logical voltage levels or is there a protocol involved?
I'm building a tank controller and I'm searching for a safe option to control some power sockets.

Here's something for the eyes for you guys :)

It connects to the controller via an RJ12 and uses 12VDC. I took some measurements on mine and determined the following:

1 - not sure, measured constant 12VDC
2 - socket 1
3 - socket 2
4 - socket 3 (assumed, I don't have anything programed)
5 - socket 4 (assumed, I don't have anything programed)
6 - common

I Assume you measured the outlet on the controller, right? So it seems to be controlled by simple voltage levels. Maybe, to make sure, I should buy one and give it a try :)

I actually bought an old GHL 2 which had a DIY plugbar using relays, plug sockets etc that worked via the S port on the GHL so no reason why it wouldn’t work the other way around :)

So I had a peek inside the power bar. It's really just a bunch of diodes and resistors. The relay is a HF115F-S.

Exactly what I needed for my DIY controller :)
