5.5.2 Radio/GPS Cable Connection

Remove the radio/GPS cable to the terminal block
on the front of the Opticom™ GPS System Phase
Selector.
1. Strip approximately 3 inches of the outer
jacket from the end of the cable. Be careful
not to cut the wires inside.
2. Strip 1/4 inch of insulation from each wire.
NOTE: It is very important to not strip too much
insulation, which may lead to short circuits; or
too little insulation, which may prevent the wire
from making good contact.

Intersection Equipment Installation Instructions
Place each wire into the appropriate terminal in
the 11-pin terminal block and tighten the screw to
secure the wire. The label on the terminal block
shows the color of each wire. Table 5-1 also
shows the terminal block pin number, wire color,
and function of each wire.
The terminal block may be removed from the
phase selector to allow easier connections.
Connect the bare wire to pin 11 of the terminal
block. Connect a user-supplied 22 to 16 AWG
wire from pin 11 to the earth ground point in the
traffic control cabinet. See Figure 5-12.
