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.
