The Configurator does seem to show this, a black link appears between the trigger socket on the primary D250 and the optical/RS232 socket on the companion. The optical/RS232 socket on the primary is configurable for either, and I guess that RS232 will be electrical rather than optical. This socket is not configurable on the companion, perhaps it is configured automatically. So it does look like an electrical cable. I hope I find out soon - I have my D800 upgrade on order.
