The manual for the unit states that it is a part number M28748-/8-D10LIA Evidently the M28748 series of connectors are fairly widely used in military equipment, but a search for that particular p/n didn't turn up anything, none of the parts houses that I deal with handle mil type connectors, and I really doubt of I would have any luck at all as an electronics hobbyist calling up a defense contractor trying to buy one connector (to say nothing of what they would want for it even if they agreed to sell one to me...). The connector is rectangular and has three rows of pins, seven in the two outer rows and six in the center. Anyone have any ideas?
