FCC Part 15 Notice
This equipment has been tested and found to comply with the limits for
a Class B digital device, pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses,
and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to

radio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try
and correct the interference by one or more of the following measures:
• Reorient or locate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for
help.
Industry Canada RSS-119 (Pending)
This Class B digital apparatus complies with Canadian RSS-119. Cet
appareil numérique de la classe B est conforme à la norme RSS-119 du

1.0 INTRODUCTION
This guide presents installation and operating instructions for the ROR
transceiver module. The unit is a compact, modular board intended for
integration inside customer-designed equipment.
The module (Figure 1) is a wireless data transceiver designed to operate
in an industrial environment. It employs two microprocessors—one for
Digital Signal Processing (DSP) control of the unit’s data port, and
another for control of modulation functions at the diagnostic port. The
module employs Gaussian-mean shift keying (GMSK) modulation.
These features provide highly reliable communications, even under
adverse conditions.

1.1 Modem Speed versus Channel Bandwidth
The module is factory configured for an over-the-air data baud rate
(
BAUD
) of 9600 bps, Gaussian filtering (
(
BW
) of 12.5 kHz. This configuration may be verified by use of the

1.2 Frequency Coverage
The ROR module is designed for operation in the 217-222 MHz
frequency band. Any combination of transmitter and receiver operating
frequencies can be programmed, including a simplex (TX = RX) pair.

2.0 INSTALLATION DESIGN
The module is designed to be an integral part of another electronic
device or system. It must be provided with adequate and stable primary
power, a complementary data interface and a suitable antenna system.
An antenna is the only external device that is needed for operation.
The module has just two connectors—one for data/power, and another
for the antenna connection. Figure 2 shows the location of these
connectors.
The data/power connector (J500) is a 16-pin dual-row header connector
that mates with a Samtec TW Series, Part No. ASP 103812-01. This
matching connector is provided on the OEM Test/Evaluation board,
described later in this manual. Data signals and DC power are applied to
the module through this board or another device to which the radio is
attached.
The Antenna/RF Output connector (J300) is located at the lower right
side of the module, and is a female MCX-type coaxial connector. A
suitable RF load or antenna may be connected to this connector.

(Module shown with shield cover removed)
In its deliverable form, the module has all of its electronic circuitry
enclosed in RF shields to minimize interaction with nearby electronic
products. Careful selection and/or routing of the unit’s antenna feedline
line may be required to minimize RFI to other electronic devices
mounted near the module. The module can be set to produce either 0.5
watt, or 2 watts of RF output using a connected terminal (requires use of
PWR
command).

For optimal communication range and reliability, this unit must be
provided with a good antenna system. A secondary benefit to an
effective antenna system is the ability to run the system at the lowest
possible power level, minimize primary power consumption, and reduce
the chance for interference.
The data interface for the module supports TTL-type signaling. Use
only the required pins for the application.

2.1 Antennas and Feedlines
Antennas
The module can be used with a variety of antennas, ranging from a
directly-connected flexible type, to a highly directional array. The exact
style depends on the physical size and layout of the radio system.
Suitable antennas are available from several manufacturers, including
Microwave Data Systems.
Preliminary
At master stations, omni-directional antennas (Figure 4) are typically
used to provide equal coverage to all remote sites in the network.

(Shown mounted to mast)
At remote sites, a directional Yagi (Figure 5) or corner reflector antenna
is generally recommended to minimize interference to and from other
users.
