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.
IMPORTANT NOTE: The OFR400 UHF LINKnet FM Modules
described in this Manual draw about 50% more current than the
OFR800 FM Modules. A Maximum of five may be used in a
LINKnet OFR1000 Card-Cage with no other modules. With other
Modules the maximums are...
With 1 other LINKnet Module:
With 2 to 3 other LINKnet Modules:
With 4 or more other LINKnet Modules:

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 LED’s do NOT flash three times, then remove the module, check the power
source, and re-insert the module, (See Installation Instructions).
If the card is “OK” the LED’s will continue normally. (See Normal Operation)
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 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.
Note that if multiple LINKnet™ Modules are used, the Instructions below
apply to the composite power output of all Modules when transmitting
simultaneously.
The Roof Top Antenna or Antennae for linking to the Donor Site(s) is/are
directional (high gain) Antennae, 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. If
multiple LINKnet™ Modules are used with output combiners into any one
Antenna, and/or multiple Antennae are used on one Roof Top, then the
sum of composite powers into all Roof Top Antennae must not exceed 100
Watts maximum. Please consult Kaval Telecom for assistance as required. The
Roof Top Antennae 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™ (+40 dBm); +28 dBm, or 0.63 Watts EIRP. If multiple
LINKnet™ Modules are used with output combiners, then the composite
power output of all Modules transmitting simultaneously must meet this
maximum EIRP requirement. Please consult Kaval Telecom for assistance as
required. 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.
