Allen Bradley PCMK 1784PCM5B pinout

[Dave]

I had a problem with a PCMK cable 1784 PCM 5B. The wires broke off the thin
flat black connector which connects to the 1784-PCMK Series B card. I
searched for the pinout information and found nothing.

I studied the broken wires very carefully and reconnected 4 broken wires and
now the cable works perfect connecting to a SLC 504 PLC. I will list the
colors which I am CERTAIN of, those with a question mark were those
replaced. Perhaps there is someone else that may confirm the colors on the
pins with the question marks.

7 pin side
Blue - certain
Green - ??
Gray - certain
Yellow - certain
Blue - ??
Purple - ??
White - certain

8 pin side has a letter "B" molded in plastic
Black - certain
Red - certain
Brown - certain
Orange - certain
Pink - ??
Tan - certain
White - certain
Green/Yellow Dot - certain


If anyone has this cable with wire that have not broken of the ?? pins and
can confirm the color for certain, I would appreciate it. Please remove the
(remove) from my email address

I have a PCM4 series A cable that my clumsiness caused a similar fate
for. Does anyone know of a source for these flat PCMCIA connectors?

As an aside, ever since I broke that cable, I started taking seriously
the adhesive "anchor pads" that come with them! They may not provide
much strain relief, but anything is better than nothing..
