Cheers guys I will definitely have a look at those pins, plus I'll open up the working units and have a gander. I'm away from work for a week but I'll post how I get on. Thank you all again.

Hi guys here are the pics of the unit. And here. And here.

Hi there Dave, unfortunately there is no display on the unit, I have opened it up hoping to see a DIP switch or something like that to select the starting address but alas there is nothing that I recognise.

Hi guys, this is probably a stupid question but hoping someone on here will have an idea. In our school Drama department we have too very ancient Horizon Dimmer units both 18 channel. We have just purchase an updated controller, cabling etc but unfortunately when connectIng both units to a splitter then into the desk both Dimmer units are running on the same DMX address ie both channel 1 on the dimmer units are running of DMX channel 1 (its worth saying we have a similar setup in our main hall with the same dimmer units but one unit is DMX channel 1-24 and the other is 25 - 40 etc). Does any one have any thoughts on how to change one of the dimmer units to run from a different DMX address? Cheers - sorry if this is an obvious question but I would be great full for some help if possible.
