Modem Use
The 822-1XRT and 882-EVDO modems are designed and intended for use in fixed and
mobile applications. “Fixed” assumes the device is phy sically secured at one location and
not easily moved to another location. Please keep the cellular antenna of the 8221XRT/882-EVDO 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 t his
restriction may result in suspension or denial of cellular s ervices 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.

001-0003-822 Rev 1
•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 822-1XRT/882EVDO 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
822-1XRT/882-EVDO modem. CalAmp DataCom recommends installation by a
professional.
The label contains the CalAmp DataCom part number, serial number, FCC ID and the ESN
numbers. The ESN number is required by your cellular carrier when activating your data
contract. The ESN number is provided in decimal and Hex formats; format is depend ent on
your carrier type.
ESN Dec: The Electronic Serial Number of the cellular module in decimal format.
ESN Hex: Same number as above but in a special HEX format.

Primary Antenna
The primary and optional AGPS antenna connections on the 822-1XRT/882-EVDO modem are
female connectors, therefore you must purchase an antenna with a SMA male connector. Do not
select a 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.
AUX Antenna
The AUX antenna is a female SMA connector which can be optionally install on the 822-GPRS
modem to be used for AGPS.
The AUX antenna connector is installed as standard on the 882-EVDO modem and can be used
for Diversity, AGPS, or both depending on the antenna attached and the modem programming.
The modem, by default, sets the AUX input as a Diversity antenna.
The 822-1XRT/882-EVDO modem can be configured via HTML web pages or AT commands on the
serial port. You will need a CDMA Cellular account. For TCP/IP please request a 1xRTT (822-1XRT) or
EVDO (882-EVDO) 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.

enter the User Name: admin and the Password: password and click OK. Refer to Figure 4.3.
Figure 4.4: 822-1XRT/882-EVDO configuration Home page
The PPP status on the Home page will show DOWN because the new device is not enabled. Also, the
MDN/MTN or MIN/IMSI lines may show an invalid phone number indicating that the unit has not

been provisioned. The modem must first be provisioned with the specific carrier before connecting
with the cellular network.
Provisioning
In order to use the modem, it must be activated by the specific carrier once the ESN has been
provided for the account. Over-The-Air (OTA) activation is supported and each carrier has a different
procedure. Refer to Sections 5 and 6 for information on provisioning for specific carriers.
Modem Network Connection
After the modem has been successfully provisioned, the cellular data connection can be enabled. At
the Home page, select “Data Connection” from the side menu bar. Fill out the Dial Number, User,
and Password fields required for the specific carrier account. The default values for Verizon and
Sprint are shown in Figure 4.5, a dial number of atd#777 and blank username and password.
Select “Enable” on the Auto Connect line and then click the Save button.
Figure 4.5: Data Connection configuration page
The DCD LED on the front panel will light when a connection to the cellular network has been
established. Go back to the Home page to verify the PPP Status is UP (Figure 4.6). The PPP IP
Address field shows the current IP address the network has assigned the 822-1XRT/882-EVDO
device as well as other PPP parameters.
The 822-1XRT/882-EVDO modem is ready to browse the web. More detailed configuration
information and activation of other features of the 822-1XRT/882-EVDO modem are given in the
following sections.
