1. PREFACE
1.1 Copyright Notice
©2011 CalAmp Corp. All Rights Reserved.
This manual covers the operation of the Sentry4G 2500 router. Specifications described are
typical only and are subject to normal manufacturing and service tolerances.
CalAmp reserves the right to modify the equipment, its specifications or this manual without
prior notice, in the interest of improving performance, reliability, or servicing. At the time of
publication all data is correct for the operation of the equipment at the voltage and/or
temperature referred to. Performance data indicates typical values related to the particular
product.
No part of this documentation or information supplied may be divulged to any third party
without the express written consent of CalAmp Corp.
Products offered may contain software which is proprietary to CalAmp Corp. The offer or
supply of these products and services does not include or infer any transfer of ownership.
1.2 Router Use
The Sentry 4G 2500TM is designed and intended for use in fixed, nomadic, or mobile
applications. “Fixed” assumes the device is physically secured at one location and not easily
moved to another location.” Nomadic” assumes the unit is installed in a vehicle but is
operated when the vehicle is stationary. “Mobile” assumes the unit is physically secured in a
vehicle and is operated when the vehicle is moving. The Sentry 4G router supports full
mobility.
1.3 Interference Issues
Avoid possible radio frequency (RF) interference by following these guidelines:
Do not operate in the vicinity of gasoline or diesel-fuel pumps unless use has been
approved and authorized.
Do not operate in locations where medical equipment that the device could interfere
with may be in use.
Do not operate in fuel depots, chemical plants, or blasting areas unless use has been
approved and authorized.
Use care if operating in the vicinity of protected personal medical devices, i.e.,
hearing aids and pacemakers.
Operation in the presence of other electronic equipment may cause interference if
equipment is incorrectly protected. Follow recommendations for installation from
equipment manufacturers.

1.4 Mobile Application Safety
Road safety is crucial. Do not change parameters or perform other maintenance of
the Sentry 4G while driving.
Avoid potential interference with vehicle electronics by correctly installing the Sentry
4G router. CalAmp Corp recommends installation by a professional.
1.5 FCC Notification
This device complies with part 27 of the FCC rules.
Changes or modifications not expressly approved by the party responsible for compliance could
void the user's authority to operate the equipment.
Note: 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.
Caution pertaining to the 4G output terminals:
This device is subject to different restrictions whether it is operated as a mobile terminal or as a
fixed station. When this device is operated as mobile subscriber equipment, the peak equivalent
isotropically radiated power (EIRP) shall not exceed 2 watts. As the default maximum conducted
output power of the device is near the allowed 2 Watts, it is required that this maximum power be
reduced by a ratio corresponding to the gain of the antenna used. For example if the 4G antennas
installed have a 5 dBi gain, the output power shall be reduced by the equivalent 5 dB, making the
conducted maximum output power 0.63 Watt at the most.
When the device is operated as a fixed station, the antenna gain shall be such that the EIRP is
limited to 40 Watts.
This configuration shall be executed by a professional installer.

2.3 External Interfaces
2.3.1 Front Panel Connections
Figure 1 –Sentry 4G Router Front Panel
Sentry 4G front panel connections include:
TRX: Two TNC female, Transmit/Receive antenna connections. See section 2.6 “Antenna
options” for more information.
WiFi: RP-SMA jack, WiFi antenna. See section 2.6 “Antenna options” for more information.
3G: SMA jack, cellular antenna. See section 2.6 “Antenna options” for more information.
ETH0 and ETH1: Inputs for standard or crossover Ethernet cable
GPS: SMA female, GPS antenna connector. This input requires a 3.3V, GPS antenna with an
SMA connection. For best coverage, use an active GPS antenna with a gain between 10 and
30 dB.
USB: USB A Female connector. Reserved for future use.
Console: 3-wire serial in a USB Mini B female form factor (requires a custom USB Mini B to
EIA-232-F DB9 cable) for debugging and maintenance only.
PWR: 10-30 VDC; the mating connector is a Weidmuller 1615800000 connector.
2.3.2 LEDs
There are nine LEDs on the front panel of the Sentry 4G unit. Each (except the Ethernet
LEDs) can display three colors: Red, Green, and Amber. The definition for each LED is as
