Field Satellites With External Antenna
The RDR retrofit decoder module utilizes the same antenna interface cable (Kit P/N 102-2013) as other E-Series
OSMAC products. This interface cable terminates with a BNC connector and can be used with short "rubber ducky" type
antenna. It can also be connected with another cable to interface with other types of external antenna. The antenna
jumper loop "W1" should be cut to initiate any external antenna.
Note: Once the antenna jumper loop is cut, the decoder module can only be used with satellites that utilizes
external antenna.
Antenna Interface Cable Installation
Step 1: Detach the black ground wire to disconnect power to the decoder module. Detach the remaining cables from
the decoder module and remove the module from the cabinet completely.
Step 2: Locate the D-shaped knockout in the lower corner of the cabinet and drill a 1/2" (12.7 mm) hole into it.
See Figure 5.
Step 3: Install the antenna interface cable to the RDR cabinet and connect it to the RDR retrofit decoder module.
See Figure 6.
Step 4: Clip the wire loop labeled W1 on the decoder module. See Figure 7.
Step 5: Connect a "rubber ducky" type antenna or cable from other types of external antenna to the antenna
interface cable.
Step 6: Reinstall the decoder module and cables. Connect the ground wire last. Test the satellite controller for proper
operation.
For satellites that requires an external antenna, service kit P/N 102-2053 is available that includes the antenna interface
cable, metal mounting bracket and short "rubber ducky" antenna to be mounted under the plastic lid.

Resetting the EEPROM
To reset the EEPROM, first remove the power from the RDR retrofit decoder module by removing the black ground wire.
Slide the switch on the decoder module from the "NORMAL" position to the "RESET" position. See Figure 8. Restore
power to the retrofit card by plugging back the black ground wire onto the spade connector. Wait 15 seconds, then slide
the switch back into the "NORMAL" position. This process will reset the EEPROM to factory defaults.
As a second option, if the base station is currently in operation, reset can be initiated using the base station's keypad or
a hand-held radio. If using the base station key-pad, choose the satellite number and key-in 8011 command.
For over-the-air hand-held command, press the "push to talk" button on the hand-held radio and send *9, the satellite
number and 8011# command.
Testing Satellite Operation
A self-test feature is provided to check the functionality of various
key satellite control circuits. Before performing the test, ensure the
Field Common, Pump and Station Output control switches are set
to the "AUTO" position.
The test is initiated by positioning the switch, located on the decod-
er module, to the "TEST" position as shown in Figure 8. Testing will
begin immediately and is indicated by the audible clicks of the control
relays and momentary illumination of the LED's on the various PCB
assemblies. The test will repeat continuously until the switch is posi-
tioned to the "NORMAL" position.
