OFR400 MODULES
Overview
Theory Of Operation
An OFR, or On Frequency Repeater, is a radio repeater that simultaneously
receives and transmits a single narrow band radio channel on exactly the same
frequency.
The OFR accomplishes its repeater function without store and forward circuitry, or
expensive conventional simulcasting techniques. The fact that the same frequency
is retransmitted by an OFR means that additional frequency allocations are not
required in situations where an existing radio coverage pattern needs to be
extended. The most common OFR applications are the extension of above ground
signals into buildings, tunnels, vehicles or the extension of radio coverage patterns
into outdoor shaded areas such as deep valleys.
From an applications standpoint, an OFR is very similar to a regular two-way radio
repeater. On Frequency Radio Repeaters can be combined using regular two-way
radio multicoupling or duplexing equipment and have input and output signal
characteristics to those of regular transmitters and receivers. The one special
consideration in OFR systems is that of input to output antenna isolation. This must
be carefully engineered for each installation.
Standard On Frequency Radio Repeaters are designed for indoor use only and are
intended for mounting in a standard EIA 19 inch rack. Modular design of OFR
circuitry allows for easy servicing, stocking of spares, adaptability and upgrade
ability.

Power On Self Test (POST)
Each system module automatically performs a self-diagnostics when inserted into
the system Card-cage. These tests determine that the unit is a) correctly installed in
the Card-cage and b) not damaged in transit.
•
•
All six of the LED’s on the front panel will flash 3 times
•
•
If the card is “OK” the LED’s will continue normally. (See Normal Operation)
If the LED’s do NOT flash three times, then remove the module, check the power
source, and re-insert the module, (See Installation Instructions).
If there is a fault, then the Red Fault LED will remain on. If this occurs, contact
your KAVAL TELECOM INC. Service Representative, (See Warranty / RMA
Procedures).
The Power On Self Test is Not an RF test, it only verifies that there is power to
the unit and that the logical circuitry is functioning.

Normal Operation
The OFR400 Module has six LED’s on the faceplate:
1. OPERATING - Under normal operating conditions, this LED will flash
GREEN when RF Data is present.
2. STAND BY – Under the control of the Controller Module, the OFR400
Module has the ability to act as a duplex transmitter, sitting perpetually in
Stand by Mode waiting for the primary transmitter to fail. This LED should be
constant Amber. If a Fault should occur with the primary module, the “Stand
by” unit will immediately become the primary unit, at which time the Stand
by LED will be turned off and the LED’s will show an operating Module.
3. Transmit – This Green LED will be on when a signal is being transmitted
4. Receive – This Green LED will be on when a signal is being received
5. Program – This LED will be constant Amber when the unit is being reprogrammed by the Controller Module. This will signify that the unit is
powered on but unavailable for use.
6. FAULT – Red LED, If the internal diagnostics for the module detect a
problem, then this LED will remain on

Antenna Installation
DCM000000019
•
All Antenna Installation is to be performed by Qualified Technical Personnel only.
•
Antenna Installation Instructions and locations below are for the purpose of
satisfying FCC RF Exposure Compliance requirements.
•
The Roof Top Antenna for linking to the Donor Site is a directional (high gain)
Antenna fixed-mounted physically on the side or top of a building, or on a tower.
The Antenna Gain must be no more than 10 dB. The Roof Top Antenna location
should be such that only Qualified Technical Personnel can access it, and that
under normal operating conditions no other person can touch the Antenna, or
approach within 10 meters of the Antenna.
•
The In-Building Antenna connection is via a coaxial cable distribution system with
Signal Taps at various points connected to the fixed-mounted Indoor Antennae.
This is shown in the figure in the Introduction. The Indoor Antennae are simple
1/4 Wavelength (0 dB Gain) types. They are used with KAVAL TELECOM INC.
12, 16, or 20 dB Cable Taps. As such the maximum EIRP will be at the first
Tapped Antenna, which will be 12 dB below the maximum signal level of the
LINKnet™ (+37 dBm); +28 dBm, or 0.63 Watts EIRP. These Antennae are to be
installed such that no person can touch the Antenna, or approach within 0.2
Meters.
ANTENNA INSTALLATION
WARNING
ALL ANTENNA INSTALLATION IS TO BE PERFORMED BY QUALIFIED
TECHNICAL PERSONNEL ONLY.
ANTENNA INSTALLATION INSTRUCTIONS AND LOCATIONS ARE FOR
THE PURPOSE OF SATISFYING FCC RF EXPOSURE COMPLIANCE
REQUIREMENTS, AND ARE NOT OPTIONAL.
ALL ROOF TOP ANTENNA INSTALLATION MUST BE SUCH THAT NO
PERSON CAN TOUCH THE ANTENNA, OR APPROACH CLOSER THAN
10 METERS.
ALL IN-BUILDING ANTENNAE INSTALLATIONS MUST BE SUCH THAT
NO PERSON CAN TOUCH THE ANTENNAE, OR APPROACH CLOSER
THAN 0.2 METERS.
