Serial and I/O Cable Installation

1. Loosen the 4 Captive screws securing the rear housing to the front housing assembly and
then loosen a gland connector for the serial cable. Refer to Figure No. 2 for an illustration of
the connector layout.

3. Remove 3" of the outer insulation jacket then remove 1/4" of insulation from each of the
wires (refer to Figure No. 3).
4. Remove the 9-connector terminal block connector from P3 on the 190 mainboard. Grasp the
terminal block connector and lift straight up away from the board.
5. Referring to the table below and the labels on the circuit board for terminal connections,
connect each wire to the terminal block.
6. To terminate a wire, loosen the screws in the terminal block and then insert the wire into the
terminal opening. Tighten the screw to secure the wire in place.
7. Repeat the procedure until all wires are in place.
