Device
Basic Specifications
Description
The NRD1 is a network relay device
to be used within a T2 mobile or
network AMR system.
The NRD1 is an environmentallyhardened transceiver intended for
“elevation” mounting in sites such as
utility or light poles, towers or
building roofs.
The NRD is a simple managed
network device. When commanded
by the G2 Mobile system or the G2
Central Host, the NRD1 rebroadcasts any M2 signals in
proximity.

INSTALLATION & WIRING
Installation
The NRD1 is intended for elevation
sites such as utility poles, light poles,
towers and building roofs. In most
cases, T2 will provide assistance on
Mounting Location
When determining a mounting
location for the desired RF coverage,
the following parameters must be
considered:
•
•
•
Topography
Elevation
Seasonal Changes
Topography: The 900 MHz signals
of the M2 endpoint radios and
NRD1 relay do not require direct line
of sight for successful
communication. However, the
signals cannot penetrate significant
structures such as hills, mountains,
large concrete buildings or clusters
of large foliage. The local
topography will dictate the RF
coverage of the area.
Elevation: The height of the NRD1 is
also very important to ensure the
desired coverage. In general, the
highest elevation possible will
optimize RF coverage.
absent in winter and present in other
seasons. The water content of leaves
can potentially cause seasonal variance
in RF coverage.
Physical Mounting
The physical mounting of the NRD1
relay should observe the following
guidelines:
•
The antenna should always be
mounted vertically upright.
•
The antenna should be physically
isolated from obstructions,
especially any metal surfaces such
as tank walls, pipes and poles.
•
The antenna should be physically
isolated from the power cable.
•
Tie wraps should be used to
securely strap the power cables to
the mounting structure.
Three separate brackets are available
for mounting purposes
•
•
•
Wallmount
Polemount Horizontal
Polemount Vertical
Seasonal Changes: Installers
should be aware of tree foliage

Antenna
The antenna supplied with the
NRD1 is a specific model and is the
only antenna which can be used.
The antenna is model PAW-MA9-7.
The antenna is intended to be
mounted directly to the NRD1
enclosure
Remote mount kits for antennas are
also available from T2.
Lightning Protection
The NRD1 utilizes a coaxial gas
discharge suppressor. This
provides protection per National
Electric Code instructions.
NRD1 Manual - PRELIMINARY

Wiring
Power
The only wiring required for the
NRD1 is the power connection. All
termination of power wires are made
to the terminal blocks on the
backplane of the unit as shown.
The unit can accept the following
power inputs through the switching
power supply:
AC Option
Input Range: 90 – 260 VAC
47 – 440 Hz
DC Option
Input Range: 120 – 370 VDC
Direct DC (Solar charger)
Input Range: 5 - 12 VDC
NRD1 Manual - PRELIMINARY
Terminal Blocks
The backplane board in the NRD has
two different terminal blocks: One for
AC power and one for DC power. Each
terminal block clearly shows the proper
termination.
Grounding
The NRD1 should always be wired with
a ground wire. This ground is
connected securely to the chassis.
2
Environmental Seals
The NRD1 enclosure is rated IP-67.
To maintain this rating, the installer
must pay special attention to the
environmental seals:
Front Plate Gasket
This is this primary seal of the
enclosure. It fits around the entire
face of the housing.
The front plate sits on the silicon
gasket as shown to the left. The
front plate must be properly alighed
with the H-shape gasket prior to
clamping with the front plate screws.
The gasket should be wiped clean
with water prior to installation. No
alcohol or solvents should be used
on the gasket as it will degrade the
material.
Cable Gland
The cable gland is the seal for the
entry of the power cable. The cable
must be fed through the nut and the
gland. Once the cable is in place,
the nut can be tightened until a
complete seal is present.

OPERATION
Operation
The NRD1 is a basic managed
network relay. The device does not
have any direct field inputs. Its
function is to re-broadcast valid M2
or M1B RF packets.
The default mode of operation for
the NRD1 is MONITOR.
In MONITOR mode, the NRD1
simply wakes up pseudo-randomly
every 3-10 seconds and transmits
its ID and internal diagnostic
information. At the end of this
transmission, the NRD1 will go into
a receive mode to check for any
host commands.
The host computer can initiate the
following commands through the r2
Transceiver:
Broadcast: This command will
direct the NRD1 to receive and retransmit any local M2 or M1B
messages for a specified duration
(default of 60 seconds)
Change Freq: This commands
directs the NRD1 to change either
its receive or transmit frequency.

APPENDIX – FCC / IC INFORMATION
FCC Information
FCC / IC Declarations
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 to correct the
interference by one or more of the
following measures:
- Reorient or relocate 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.
The M2 Utility Radio Tranceiver is an
approved intentional radiator device under FCC
15.247 and Industry Canada under RSS-210.
THIS DEVICE COMPLIES WITH PART 15
OF THE FCC RULES. OPERATION IS
SUBJECT TO THE FOLLOWING TWO
CONDITIONS:
(1) THIS DEVICE MAY NOT CAUSE
HARMFUL INTERFERENCE, AND
(2) THIS DEVICE MUST ACCEPT ANY
INTERFERENCE RECEIVED, INCLUDING
INTERFERENCE THAT
MAY CAUSE UNDESIRED OPERATION.
The NRD1 Relay is a self-contained unit and
access to its circuitry by an end user, other than
for installation, wiring or replacement of the
battery, is not intended. The supplied whip
antenna is the only antenna authorized for use
with the NRD1. Changes or modifications not
expressly approved by Transparent
Technologies or use of the radio other than the
purposes described herein voids the user's
authority to operate the equipment.
Industry Canada product labeling.
“IC” before the equipment certification number
only signifies that the Industry Canada
technical specifications were met.
