E-Series OSMAC Digital Wireless Paging System Satellite Controller
Wide Band to Narrow Band Conversion Kit
Installation Instructions
Installing the Narrow Band Decoder Module
1. Place the satellite AC power supply switch in the Off position.
2. Remove the clear plastic cover from the decoder module assembly
3. Release the ribbon cable connector from the decoder module by moving the cable receptacle locking tabs outward.
4. Disconnect the remote antenna cable (if installed).
Figure 1
5. The decoder module is secured by a self-locking nylon standoff in each corner of the PCB. To remove the module, compress the standoff locking tab
(indicated in Figure 1) using needle nose pliers or a flat blade screwdriver,
then carefully lift the module upward just enough to keep the locking tab
compressed. When all four standoffs are compressed, remove the module.
6. Position the narrow band decoder module onto the standoffs (in the same
orientation as the wide band module), then simultaneously press downward
on all four corners of the module to lock into position.
7. Place the (keyed) ribbon cable into the receptacle and push inward to lock
into position.

8. For remote antenna connection: Connect the short antenna cable assembly

(supplied in the kit) to the receptacle on the decoder module (A) and the antenna or antenna cable BNC receptacle. Using small wire cutters, clip the wire
jumper (B) located to the right of the de antenna receptacle. See Figure 2.
9. Place the satellite AC power switch in the On position.
10. When testing is complete (as per instructions on page 2), reinstall the decoder
module cover.
Selecting the Decoder Radio Frequency
The narrow band decoder module stores four user-selectable radio frequencies.
The frequencies are programmed at the factory or by the distributor prior to delivery. A set of jumper pins, located at the top center of the decoder module, enable
the desired frequency to be selected by placing the jumper on the appropriate pin
set. In most cases, the jumper will be configured properly by the distributor prior to
delivery. However if a frequency change is desired, place the jumper on the
desired pin set number as indicated in Figure 3.
Figure 3
Important: The base station transmitter and decoder module must be set to
the same frequency to enable communication.

Assigning the Satellite Address Number
Each satellite requires a 3-digit address number to enable communication with
the central controller and/or a hand-held radio. The address numbers range from
1 (001) through 255 and are issued to the satellite through an array of eight DIP
switches, located on the decoder module assembly. See Figure 4. In the down
position, the switch is Off (open) and represents a value of 0 (zero). In the up
position, the switch is On (closed) and represents the following address number:
Sw 1 = 1
Sw 2 = 2
Sw 3 = 4
Sw 4 = 8
Sw 5 = 16
Sw 6 = 32
Sw 7 = 64
Sw 8 = 128
To set the satellite address number, place the switch or combination of switches
to the On position which provides the numerical equivalent of the desired
address number.
For example: To set satellite address number 50 (050), start with all eight DIP
switches in the Off (open) position, then close switch numbers 2, 5 and 6;
i.e., 2 (Sw 2) + 16 (Sw 5) + 32 (Sw 6) = 50.

Performing a Control Circuit Self Test
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 (down) position.
The test is initiated by positioning the TEST/RESET switch, located on the
decoder module, to the TEST position as shown in Figure 5. 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 TEST/RESET
switch is positioned to the center (normal operation) position.
Note: The RESET position resets the decoder microprocessor to factory
defaults. To take affect, the satellite must be powered up with the
switch in the RESET position. The switch should be placed in the
NORMAL position after 15 seconds of operation.
