RavenXT-Series
Sierra Wireless Airlink Digital Cellular Modems
The RavenXT-series modems are full-duplex devices
that transmit data to the local cellular tower. A PC
retrieves the data from the cellular tower via the
Internet*. Internet communications provide faster
communication rates and eliminate dialing delays
and long distance fees.
e following modems are oered:
RavenXTV• —Code Division Multiple Access
(CDMA) modem congured for Verizon networks
RavenXTG• —General Packet Radio Service
(GPRS) modem congured for AT&T networks
Features
Eliminates the dialing delays and long distance•
fees that land-line phone modems experience
Allows simultaneous communications with•
multiple dataloggers in the network
Housed in a rugged aluminum case•
Operates over a wide operating temperature•
range (see specications)
Cellular Coverage
Before purchasing a digital cellular modem, ensure
that there is a CDMA or GPRS network with cover-
age at the datalogger site. For the RavenXTV, you’ll
need to contact Verizon and ask them about coverage.
For the RavenXTG, a coverage map is available at:

Typical System*
*e RavenXTV uses 1xRTT/EVDO to communicate over the Internet. It can also use IS-95 to communicate over standard telephone lines.
Contact Campbell Scientic for system requirements if using IS-95.

Establishing Cellular Service
Raven XTV
Call Verizon at 1-888-384-1775 and set up an account.
When setting up the account, you will need the ESN
number, which is listed on the modem’s label. To use
1xRTT/EVDO, you should ask for the Broadband
Plan, and either a static or a dynamic IP account. A
static IP account eliminates the need for a third party
Dynamic Domain Name System (DDNS) such as IP
manager. e DDNS translates the domain name to a
dynamic IP address so that the modem can be con-
tacted as if it had a static IP address.
RavenXTG
Call AT&T at 1-800-331-0500 and ask for an un-
restricted data account for a GPRS modem. Either
a static IP account or a dynamic IP account needs
to be established. Aer the account has been set up,
mobile termination needs to be congured onto the
account to make the modem accessible through the
Internet. is is done by adding an I2gold APN1or
custom APN2to the account. A data account with
an I2gold APN will have a Static IP address.
Aer establishing service, AT&T will provide a SIMM
card for each modem. In some cases, the SIMM card
can be picked up at the local AT&T store.
Datalogger Site Equipment
Digital Cellular Modem
e RavenXTV and RavenXTG are shipped with a power
cable, our Resource CD, and a CD containing the Airlink
soware and the Airlink manual. e modems are con-
gured using the following soware:
Airlink AceManager soware• —activates the
modem and congures the generic parameters
of the modem.
Campbell Scientific’s Raven CDMA Tem-•
plate (RavenXTV) or Raven GPRS Template
(RavenXTG)—used with Airlink AceManager
soware to congure the modem. e template
sets up the Raven serial interface, which is specic
to Campbell Scientic systems. e Raven CDMA
Template and Raven GPRS Template are available,
at no charge, from: www.campbellsci.com/downloads
Network connection information can be viewed using
the Airlink AceManger or Airlink AceView soware.
Datalogger Connections
All of our contemporary and many of our retired data-
loggers are compatible. e datalogger connects with
the modem using one of the following devices:
18663 Null Modem Cable• —connects the modem
directly to the datalogger’s RS-232 port. is cable
is the only option available for connecting the
modem to a CR200(X)-series datalogger.
SC105 DCE Interface• —connects the modem to
the datalogger’s CS I/O port via an SC12 cable.
e SC105 is recommended for PB® data-
loggers when the RS-232 port is unavailable.
SC932A DCE Interface• —connects the modem
to the datalogger’s CS I/O port via an SC12 cable.
e SC932A is recommended for mixed-array
dataloggers when the RS-232 port is unavailable.
Power Considerations
A power cable included with the modem connects
to the datalogger’s 12 V or switched 12 V terminal.
Connection to the switched 12 V terminal allows the
datalogger to switch power to the modem during
scheduled transmission intervals, thereby conserving
power. When using the switched 12 V terminal, the
modem can be powered with a BP12 battery, CH100
regulator, and SP10 solar panel. For help on analyzing
your system’s power requirements, refer to our Power
Supply product brochure or application note.
One of the above is required to connect the datalogger to the
modem. The best choice for your application depends on the
datalogger you are using.
1At one time, feature code G821 was used instead of the I2gold APN. Feature code G821 has been discontinued, and all RavenXTGs need either
an I2gold APN or custom APN.
2A custom APN may oer more ecient routing and better security for large cellular phone networks. It will take four to six weeks for AT&T to
develop a custom APN and cost about $250.00.

Antennas
A choice of four antennas is oered for the modems.
Contact an Applications Engineer for help in deter-
mining the best antenna for your application.
21831 0 dBd, ½ Wave Dipole Whip Antenna• —
supports the 800 MHz band. It is intended for
locations that have strong cellular coverage. is
antenna attaches directly to the modem’s SMA
connector and must reside in an environmen-
tal enclosure or building. It has an articulating
knuckle joint that can be oriented vertically or at
right angles.
18285 1 dBd, Omnidirectional Antenna• —covers
both the 800 MHz and 1.9 GHz bands. It includes
a mounting bracket for attaching the antenna to a
crossarm, tripod, tower, or pole. Connection to the
modem requires an antenna cable (see right column).
20679 800 MHz/0 dBd and 1.9 GHz/3 dBd•
Omnidirectional Antenna—includes a mounting
bracket for attaching the antenna to a crossarm,
tripod, tower, or pole. Connection to the modem
requires an antenna cable (see right column).
10530 9 dBd, Yagi Antenna• —supports the
800 MHz band and is intended for sites near the
edge of the cellular coverage. It includes a bracket
for attachment to a mast or pole (outer diameter
of up to 1.5” (3.8 cm)). Some sites may require
the CM230 mount (see Adjustable Angle Mount-
ing Kit). Connection to the modem requires an
antenna cable (see right column).
Antenna Cables/Surge Suppressor
Typically, a 21847 or COAXSMA-L cable is used with
a 18285, 20679, or 10530 antenna. Both of these cables
have a type N male connector on the antenna end and
an SMA connector on the transceiver end. ey dier
in their length:
21847 Antenna Cable with 12- Length•
COAXSMA-L Antenna Cable with User-specied•
Length—enter cable length, in feet, aer the L.
Length should not exceed 20  (6 m).
Use the following when the modem is in an environ-
ment susceptible to lightning or electrostatic buildup:
COAXNTN-L• antenna cable with type N male to
type N male connectors (requires 19533)—specify
length, in feet, aer the L. Cable lengths longer
than 20  will weaken the signal strength.
19533 Antenna Surge Protector Kit• —includes
one COAXSMA-L1.5 cable. A COAXNTN-L
cable is required (see above).
Adjustable Angle Mounting Kit
e CM230 Adjustable Angle Mounting Kit allows
the 10530 Yagi antenna to be aimed at the service
provider’s antenna.
Enclosures and Mounting Bracket
An ENC12/14, ENC14/16, or ENC16/18 environ-
mental enclosure can house the modem, datalogger,
and power supply. e modem is secured to the
enclosure’s backplate via the 14394 Mounting Bracket.
Base Station Requirements
PC running PC400 or LoggerNet Datalogger•
Support Soware.
Access to the Internet.•
Above are antennas used with the RavenXT-series digital cel-
lular modems. The 20679 antenna is not shown.
COAXNTN-L
Surge Suppressor
Installations that are susceptible to lightning should use the
COAXNTN cable and 19533 surge protector kit.
