need help with skeet machine relay box

Hi,

We have a bit of a problem we hope someone out there can help us with.  We have 3 duematic card system readers (Pic1) they are talking to some mystery relay box we have NO documention on at all. (Pic 2)  There is a sticker on the side of the box but we don't think it's Duematic. (Pic 3)  

Also a second sticker inside showing a block diagram. (Pic 4)   We're trying to replace the pull cords on the Skeet machines with the these new Promatic RTM1's

Here is the new Promatic RTM1 units (Pic 5) and the PCB inside the unit. (Pic 6)    Here is a close up of the output pins on the Promatic. (Pic 7)

-----------------------------------------------------------------------------------

We don't know what or who makes thei relay box and are trying to find a schematic or a manual for them and no one here has nay clue abouthtem or how its wired.  So far we've toned out the pull cord and we think that the 3 wires coming on to the relay box are:

JP4 RELEASE

White wire on header = Pin 1 = Ground
brown wire on header = Pin 2 = High House
green wire on header = Pin 3 = Low House

So we've tried to replace that plug in connector goin in to the box with the signals from the RTM1 and if you tone it out - it works - but plug it in and the trap machines either won't fire at all or they do and the card reader does not count the targets used.

ANY help at all with this would be appericated.
