Figure 2. POS4000 Connections
The wall transformer plugs into a 3-prong earth grounded wall outlet, the connector at the end of
the cord attaches to the mating connector on the back of the main console. This cord connects
the power and Earth Ground connection to the Console.
The main console and interface board are connected by a communication cable. The correct
communication wiring is pin 1 to 1, pin 2 to 2. The shield should be connected to earth ground at
the interface board (connector C pin 4). See the wiring diagram in the table on the following page
for more detail.
