I swapped pins 2 & 3 at the serial connector and got the ominous windows blue screen that lets you know you've done something SERIOUSLY wrong. It popped up with a VCOMM error "press Enter to return to windows, or CTRL, ALT, DEL to really **** your computer off". And the Microsoft police called to let me know they were starting a case on "computer abuse" and that I'd be investigated if the problem persisted.

Anyhow, that's the latest.

something is not right with your wiring because even with mine swapped I dont get a blue screen

Well that's reassuring.

I was hoping the error was in my work and that I wasn't sitting on a bad XMD1000. The Mrs. has a photo shoot tomorrow - that will be a good chance to sit down with this thing and dissect it to see what's wrong.

I'll throw in a little more information if it might help. I got the serial cable end as part of a serial extension cable. And I got the DIN cable end as part of a DIN extension cable. I just cut the ends off with 6" pigtails, opened them up and started doing resistance checks to identify which wire went to which pin. Once I was finished, I made sure none of the wires were shorted to each other or to the shield wire (including the wires I wasn't using). And I verified the shield had continuity at both ends as well as ground, trans, & rec.

so then you might be grounding DCD (Data Carrier Detect) Pin1, instead of having pin 5 connected which is ground on the serial connector. maybe try flipping that as well

because the image on the post was on the back of the computer not of the cable. so you would hook it up in reverse if you were going by the cable.

Oddly, I can't get the original images you posted to open now. But I do recall the one showing the perspective from the computer. The cable I used had the terminals numbered and I used that as my guide, and, when reversed, my numbers matched your picture of the computer connector.

where did you connect the power to on the din, you should supply 12v to pins 6&7, ground to pin 8.

ok, good, just trying to make sure of everything here.

While I had the cables opened up, I soldered 6 & 7 together and soldered the power wire on. And eight got the ground wire soldered to it. All the solders are wrapped in heat shrink tubing with the a final covering of sealing, heat-shrink tubing socked on when the work was complete. Basically, the power and the ground wires stick out the side of my cable.
