URC-102 MASTER CONTROLLER

Mounting
The Master Controller can be mounted in any position near the Searchlight that is protected
from the weather. Check in advance that the coax cable from the Point Pad™ and the wiring
harness from the Searchlight can be routed to this location. Mount the Master controller with
the wires and coax facing down. Use an appropriate fastener for your mounting location. Use a
sealant in fastener holes to prevent moisture intrusion.
General Wiring Scheme
The RCL-50B has a unique wiring scheme. Special attention must be paid to the following
chart. The Master Controller is supplied with an in-line fuseholder on the Orange power lead.
Use only 15 amp fuses in this fuseholder. See Figure 9 for the Master Controller wiring
diagram.
NOTE: Failure to follow this arrangement may damage components.

** NOTE: This wire MUST be fused with a 15 amp fuse in the Master Controller's in-line
fuseholder.
Wiring to Searchlight
The RCL-50B Searchlight is supplied with a 12 foot integral wire harness. This wire harness is
cut to this length specifically to allow for a voltage drop. Shortening the harness will decrease
the life of the bulbs. Any extra length of wire harness should be loosely coiled in a convenient
place. For best performance, the controller should be attached to the end of the 12' Searchlight
wire harness. If you must lengthen the wire harness, use heavy duty wire to minimize the
voltage drop. This is especially important for the YELLOW lamp power and GREEN lamp
ground wires.
Following the wiring scheme shown in Table 1 use the supplied butt connectors to connect the
Master Controller to the Searchlight.
Wiring to Point Pad™
The RG-59 Coax cable is supplied without the "F" connectors attached for ease of routing.
After the coax has been routed, strip the insulation and crimp the "F" connectors in place.
Screw the "F" connectors to the Master Controller and the Point Pad™.
