This manual covers the operation of the CalAmp 882-GPRS, 882-EDGE, and 882-HSPA
Cellular Data Modem IP Routers. Specifications described are typical only and are subject to
normal manufacturing and service tolerances.
CalAmp reserves the right to modify the equipment, its specification 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.
Products offered may contain software which is proprietary to CalAmp. The offer or supply
of these products and services does not include or infer any transfer of ownership.
Modem Use
The 882 GSM Series modems are designed and intended for use in fixed and mobile
applications. “Fixed” assumes the device is physically secured at one location and not easily
moved to another location. Please keep the cellular antenna of the 882 GSM Series modem
at a safe distance from your head and body while the modem is in use (see below).
Important
Maintain a distance of at least 20 cm (8 inches) between the transmitter’s antenna and any
person while in use. This modem is designed for use in applications that observe the 20 cm
separation distance.
Interference Issues
Avoid possible radio frequency (RF) interference by following these guidelines:
•The use of cellular telephones or devices in aircraft is illegal. Use in aircraft may
endanger operation and disrupt the cellular network. Failure to observe this
restriction may result in suspension or denial of cellular services to the offender,
legal action or both.
•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.

Mobile Application Safety
•Do not change parameters or perform other maintenance of the 882 GSM Series
modem while driving.
•Road safety is crucial. Observe National Regulations for cellular telephones and
devices in vehicles.
•Avoid potential interference with vehicle electronics by correctly installing the 882
GSM Series modem. CalAmp recommends installation by a professional.
The label contains the CalAmp part number, serial number, FCC ID and the IMEI numbers.
The IMEI number is used by the GSM network to identify valid devices. The IMEI is only used
to identify the device, and has no permanent or semi-permanent relation to the subscriber.
IMEI Dec: The International Mobile Equipment Identity number of the cellular module in
decimal format.

Primary Antenna
The primary antenna connection on the 882 GSM Series modems are female connectors,
therefore you must purchase an antenna with an SMA male connector. Do not select an SMA
antenna with “reverse polarity” or RP-Male. When using a direct mount or “rubber duck”
antenna, choose the antenna specific to your band requirements. Mounting options and cable
lengths are user’s choice and application specific. The AUX antenna connector is installed
standard on the 882-HSPA modem and can be used for Diversity or True GPS.
Page 12 of 59
001-0003-832 Rev3
The diversity port on the device supports three bands, Cellular (850MHZ), PCS(1900MHZ), and
GPS(1575MHZ). Connect a dual band cellular antenna to this port to implement RX diversity on
the unit and increase receive sensitivity on the cellular network. Connect a GPS antenna, with an
average gain >-5dBi, if using the GPS functionality. If both RX diversity and GPS are required,
install a Cellular/GPS combo antenna.
GSM Communications
Only GSM models have SIM cards. Your wireless service provider will supply the SIM card with
your wireless service contract.
The 882-GPRS supports GPRS data.
The 882-EDGE supports EDGE and GPRS data.
The 882-HSPA supports HSUPA, HSDPA, EDGE and GPRS data.

The 882 GSM Series modems can be configured via HTML web pages or AT commands on the serial
port. You will need a GSM Cellular account and a carrier provided SIM card. For TCP/IP please
request a GSM account with Mobile IP and optionally Static IP or Simple IP (SIP). This is carrier
dependent.
The modem is configured with default settings and is ready to be configured via HTML. You may
need to activate the modem with your carrier to start using it. The default settings are programmed
for most operations.

Inserting the SIM Card
Power down the unit and insert the SIM card with the gold side up as shown in Figure 3.5. Push the
card completely into the slot until it clicks in place.
Figure 3.5: SIM Insertion
Power up the modem and return to the Home page to confirm the modem recognized the SIM card.
The MDN may show the phone number and the IMSI and carrier information should display. Also,
the PPP connection may not show as up until the SIM card is unlocked. Refer to Figure 3.7.
Select SIM Settings from the left side menu bar (Figures 3.6 & 3.7) to go to the SIM settings page.
Figure 3.6: SIM Page (with SIM accepted)
The SIM STATUS should show the card is ACCEPTED. The PIN STATUS may show the PIN to be
DISABLED or ACCEPTED. Refer to Section 4 for information on changing the PIN and PIN status.
