Anybody out there running a Dichro 45 with a D.A.T.A. Module?

I've "restored" a couple of 45s that are working fine now :-) NICE machines (even if they are old)

I have a third Dichro 45 with the D.A.T.A. module interface and found D.A.T.A. module (e-bay). I have everything working fine except that my filtration/density displays stay at "000" and don't change, no matter what filter settings I dial in.

I strongly suspect this may have something to do with the D.A.T.A. module and something I haven't set right to make the displays active. I have a D.A.T.A. manual on the way (from one of our kind board-mates!) but I'd like to confirm if this unit will work right or if I still have another "bug" to track down and smash.

If anybody is familiar with the D.A.T.A. module and can help me, I'd be much in your debt!

(Yea, yea, I know. The kind of "help" I really need isn't available on this board......)

Thanks gang!
