Before You Start Installing

Only experienced technicians familiar with installing similar types of hardware
equipment should install the modem. For safety and to avoid damage to the
modem or vehicle wiring, the installer should have knowledge of the following
subjects.

• Automotive wiring (if applicable)

• Vehicle cable routing (if applicable)

• Antenna location

Installation Planning

Planning is the key to a quick and simple installation. Before drilling holes or
running wires, you should inspect the vehicle or area of the building to

RFM-4200-5015 Rev1

13

iR1200 Modem

determine how and where you intend to mount the modem, antenna and
accessories. (See Required Installation Components listed on page 3).

Planning Modem Location

Factors to consider when planning for the location or placement of your iR1200
modem:

• Easily Accessible – You should allow easy access to the modem (for
troubleshooting purposes).

• Easily Visible – You should allow a clear view of the modem’s LED
indicators.

• Proximity of the Cables – The distance between connections affects
performance, especially the distance between the modem and antenna. The
shorter the distance between these components, the better the signal.

(Please refer to the antenna’s Safety Warranty for proper installation
of modem and antenna.)

• Environment Considerations:

!

- Heat - Placing the modem, antenna or cables near

a heat source can cause several problems,
including radio interference. Select a location away
from a source of heat and make sure the modem
has at least a 1-inch clearance on all sides for cool
air to circulate.

- Wetness – The modem should not be mounted in

an area where it would be directly exposed to
water.

- Direct Sunlight – The modem should not be

mounted in direct sunlight.

Modem Dimensions

Consider the size of the modem. Will the modem fit in the area where you want
to perform the installation?

14 nextel.com

Installation Preparation

The following diagram outlines the modem’s dimensions:

NOTE: This diagram depicts the dimensions of both the iR1200 Rugged

and iR1200 GPS-Enabled Modems and should not be used as a
template for mounting the modem.

Figure 4 – Dimensions of iR1200 GPS-Enabled Modem

Width of enclosure 4.04in. [102.62mm]
Height of enclosure 2.20in. [55.88mm]

Planning Antenna Location

Factors to consider when planning for the location or placement of the antenna:

• Choose a location with easy access to cable routing to ease the process of
connecting the antenna to the modem.

• In vehicle installation, mount the modem antenna on the center of the
outside trunk for optimum signal reception.

• In a stationary (building or desk) environment, position the GPS antenna
where it has a direct line-of-sight to the sky. In some cases, this can be
accomplished by placing the antenna adjacent to a window. In most cases
it will require mounting outside of the building.

Planning Cable Layout

Once you have chosen the location of the modem and antenna and before the
installation, layout the cables to determine:

• If the cables can reach the modem and antenna.

• If the distance between components is adequate and allows you to make

adjustments to receive a better signal. (Please refer to the manufacturer’s
installation manual for safe installation of your antenna).

16 nextel.com

Installation Preparation

• If there are kinks or bends in the cable or obstructions in the vehicle that
could affect routing.

Serial Cable Routing

Serial cable routing is the most important factor to ensure a trouble-free
operation. The serial cable should be as stable as possible (e.g., it should
experience little or no movement and have very few or no bends or kinks).

NOTE: The majority of the problems occur because of serial cable failure.

Installation Tools

You will need these tools to install the iR1200 modem.

• Portable Drill • Hammer

• Center Punch • Connector Crimp tool

• Four #10 self-tapping sheet metal screws • Phillips Screwdriver

installed in such a way as to maintain a separation
of at least 8 inches (20 cms) between the antenna
and the human body.

• Ensure that the antenna is properly installed
external to the vehicle and in accordance with the
requirements of the antenna manufacturer/supplier.

• Use only an approved antenna. Unauthorized
antennas, modifications or attachments could
impair call quality, damage the modem, or result in
the violation of FCC mandates.

impedance.

2 Position the antenna where it has a direct line-of-sight to the

satellite.

3 Mount the antenna according to the manufacturer’s

specifications or instructions. (Use only an approved
antenna – see list of Approved Antennas on page 31.)

NOTE: Because of the operating frequencies involved with the GPS

signal, splicing or using adapters to extend the length of the
antenna coaxial cable is not recommended and will likely prevent
the system from operating properly. We recommend that a single
length of coax without splices or adapters be used.
