Early desktop panel were DC powered from a mains power supply unit connected via a mini 
DIN connector on the rear. From 2003 onwards, panels have an internal mains power 
supply. The only remaining user connection is to the Headset connector on the rear of the 
desktop. 

The following wiring applies to panels marked "Mod State 2" and later. Earlier panels had 
pins 4 and 6 transposed internally, with corresponding changes to the interconnecting cable. 
The later wiring allows operation over longer cable runs.
