What signal does the Type 'r' centre diff require to lock/unlock it ?
Is it 12v applied to the electromagnet via a variable resistor ? (thumbwheel ? )
If disconnected from the electrical supply can I assume it is in the 'open' position ?

It has it's own ECU, I believe the thumbwheel is just an input into this, along with hand brake and throttle.
Probably as simple as a variable duty cycle controller giving a variable voltage. DC motor controller might be the best way forward, or the £450 mapped ECU from townend garage.

Inputs are thumb wheel and hand brake (to open)
Gems ecus for MY99-00 only operate the diff via throttle position, it can be mapped as you like.
The ecu can also use the input from the brake light, doesn't work well with left foot braking though.
I have a switch on the dash to change between normal (thumbwheel) and auto (TP only).
AFAIK it's available as a seperate ecu for £450 from TEG.

TEG handed over development and production to gems.
They now sell a separate ecu purely for this purpose. I believe it works out at about £250 mapped and in the car and comes with a variety of maps for different driving styles.
To my knowledge, closure locking voltage of the diff is more like 0.6 volts.
Andy, if you get one, let me know what you think of the handling afterwards. Have heard very good feedback on these but am always sceptical since it has no input from steering angle, and only has digital input from brakes based on brake light.
