Also.. just a little feedback.. for Tracy (cause I know he will read this eventually).. basing this suggestion on something someone attributed to Al Wick on reducing human factors. On the back of the EM2.. there is a 15 pin dsub and two 25 pin dsubs.. with the admonition not to get the connectors mixed up. If mixing up the connectors would cause failure of a smoke test (let the smoke out, and the box doesnt work anymore)... then wouldnt it be a good idea for future generations of this device have non-compatible connectors for the various plugs? Like a 37 pin in lieu of one of the 25's.. or one 25 pin being male and the other 25 pin being female? I'm not trying to complicate your world, but something like this MIGHT reduce one possible link in the chain of failure. That being said, i dont even know if this is a solution for a problem that hasnt manifested itself.
Whittle you a pin out of some hard plastic. Stick it in a unused hole on the plug side of one of the connectors, and remove the corresponding pin on it's mate.
Whittle another plastic pin and plug a hole in a different spot on the other side.
Be careful not to be rough when plugging in. This technique is used a lot in electronics. It allows for the same connector to be used in many places, keeping the parts count lower. This is a major concern, especially when you're doing such small runs as the EM2.
Another solution is to cut a spacer to fit between the plugs and then tape/bolt/epoxy them together so that they go in and out as one unit.
