It might be RS-485 and so multiple displaies could have its own address on a multidrop setup. About the only trick there is finding out if its 2 or 4 wire 485 (probably 2 because of the address). Think I've seen some USB to 485 converters on the market, but you might get away with driving it with RS-232.

So off of an impulse (and low bid of $9.99) I bought a Kode 375-928 display off eBay. No picture or anything in the auction, but I figured I would take the chance and hopefully nobody else would bid. A huge box came today, and guess what was inside? This display has to be about 3 to 4 feet long! It has 12 alpha-numeric type digits (broken up in to three groups of four). The back interface has only a 25pin dsub connector along with jumpers for baud rate select & address select. There's a couple more holes for additional connectors but they are not installed. Inside it is pretty bare, there's the power supplies, PCB for the front display digits, then another PCB with a bunch of socketed chips which I'm guessing is the brains. I'll have to probe the (serial?) port tomorrow when I get to the office. I'll also take some pictures, this thing is pretty cool looking. So, my question is... Does anyone have any sort of experience with these kind of Kode displays? Or just a generic hunch about the interface? I was thinking maybe it was a BCD port, but I've never seen one with a baud rate / address selection. The only other Kode I have uses a simple BNC input for IRIG-B.
