Ritron RRX-450/452/460 Repeater Interface
to Trident Raider/ Marauder
This RRX–RMC cable is available directly from RITRON
Contact RITRON for specific details
W22/ W30 = DISC INPUT GAIN SET (i.e.: input audio from RRX to CNTRLR.), >2V
P-P (see page 28, SQUELCH LEVEL), U1–1.
*
W26 OUT can lead to distortion problems on the "TX AUDIO OUTPUT" (Trident Pin
3). This will likely require a resistor (~36
+ k), across high gain feedback resistor R15
(100k or 220k) in circuit, or in series with low gain 10k resistor (across W26 pins).

IMPORTANT:
Ritron RRX Repeaters are best when using the shortest (20 mSec) firmware versions "lead-in delay," but can
use any Trident firmware. Specify "Ritron RRX" when ordering Controllers. Each brand of RF equipment is
unique to its own system installation. These jumper and switch indications are meant to be used as initial
settings. Adjustments to these settings may be required, depending on your system configuration.
