Step 6: Connect the ribbon cable, orange 12 V a.c. power wire, red
26 V a.c. power wire and terminal block wires. Connect the
black ground wire last to ensure power is not applied to the
RDR retrofit decoder module until all other connections are
made. The position of wires are labeled on the module and
shown on Figure 4. The red LED should illuminate indicating
proper connection. Position all wires in cabinet to prevent
interference with cabinet door.
Step 7: Test communication and RDR controller operation.
• Confirm the RDR field satellite is ON by observing the red LED on the decoder module.
• With the RDR field satellite address set and the power on, send a series of commands to the field satellite
using the Base Station programmed to the correct transmitting frequency and controller address. Verify that
the LED on the decoder and frequency module is blinking which signifies that it is receiving the Base Station's
commands.
• Once proper operation is observed, verify that all connections are tight and secure.
Step 8: Close and lock the cabinet to ensure protection from elements.
RDR Retrofit Module Troubleshooting Guide
Problem
RDR does not respond to
hand-held commands.
The LED on RDR decoder
module does not
illuminate after all wires
are installed.
The RDR does not respond
to the base station.
Communication is
sporadic.

Possible Cause
Incorrect address code being accessed.
Hand held battery power is low.
Frequency select jumper is incorrectly set.
Jumper loop is not cut when using an external antenna.
Data in EEPROM is corrupted. See Resetting the EEPROM on page 3.
Improper wire connections.
Wires are not securely installed.
The transmit frequency on the base station is not the same frequency as the frequency
on the RDR retrofit decoder module.
Frequency select jumper is incorrectly set.
Jumper loop is not cut when using an external antenna.
Data in EEPROM is corrupted. See Resetting the EEPROM on page 3.
The signal strength in decibel fade is weak. If it is below 16dB, an external antenna
maybe necessary.
Cabinet ground does not meet product specification of 10 ohms or less.
