RACOM model 700 CWID module

Just a long shot, does anyone have info about these modules? I have several,
would like to be able to program them. Also any installation instructions.
Searching the interwebs turned up next to nothing except old addresses
and dead links...

It figures.
I've been dragging several RACOM ID'er manuals around for about 30 years, but threw them away maybe last year.
They made a few different kinds.
One used little round switches that selected the ID letters and numbers. The "banks" of switches probably dialed the
binary or maybe BCD value to get A thru Z and 0 thru 9, too long ago to remember exactly.
But that was the best one because you could change the ID with a small screwdriver.
The later ones used a PAL (think one time burn PROM) 82S129 I think.
The last ones used a 2732 or 2716 I think. Or the 27C32 UV erasable EPROM.
Been years since I had any that I used.
The PAL and 2732 (16) versions programmed VERY much like the Hamtronics COR-4.
You might be able to reverse engineer the programming from that.
I hate it when this happens.
Seems like every time I throw away old manuals, someone needs the info from them.

Thanks for the reply. I figured out 4 of the 6 wires, +12, ground, audio out, and PTT out.
The other 2 run to the PAL, I was hoping to find a "COR" equivalent to kick off the ID.
Might have to add a wire and use the TEST switch to do that. One module was labeled
with the correct CWID I need (Legacy equipment, interfacing with a Daniels TX)

Update, the unit has a microprocessor (MC705K1P), a 1K serial EEprom, (93C46AEN) and a
14 pin header. I believe that this was field programmable (with some sort of programming cable)
6 wires out of the module, Com, +V audio out, PTT out, and what looks to be 2 inputs. (Series diode
and pullup resistors to +5)

well, good luck with it.
