That might be a good approach. The DELUA end of the cable has a Berg connector, and the other end has the typical 15-pin D-sub AUI connector with a slide latch. I'll look up the cable wiring to see if signals that would best be twisted pairs are conveniently placed on adjacent odd/even pins, such that twisted pair ribbon cable would work well electrically.

Or maybe I can use the round cable that I already have, with P-shaped cable clamps screwed down using the screws at one end of the flat cable clamps. There may not be enough clearance in the tray for that.
