Chapter 1 – Product Description and
Specifications
Product Description
The Multi-Tech MultiModem® iCell is a m id-range wireless modem containing an embedded TCP/IP protocol stack for Internet
connectivity, serial and USB connectors for modem configuration, and a General Purpose Input/Output (GPIO) connector f or
customer interface connection. All MultiModem iCells can be desktop or panel mounted.
The MT CMR contains an embedded TCP/IP protocol stack to bring Internet connectivity to any device w ithout mak ing ch a nges
to its hardware design. Using the Internet protocols and the w ireless con nec tion to an IP netw or k, the modem sends and
receives data over the Internet. The modem offers short message service (SMS) features such as text and PDU, Point-to-point
(MT/MO) and cell broadcast.
The MultiModem iCell modem delivers some of the fastest cellular wireless data speeds using the various Internet protocols.
This is ideal for highly data-intensive app licat io ns such as remote vi deo surv ei llan ce and ot her multi med ia appl ic atio ns wher e
you are sending digital images, web pages and photographs.
The MultiModem iCell modem is designed around a wide variety of interface options including serial RS-232, USB, and General
Purpose Input/Output (GPIO). The serial RS-232 and USB connections provide seamless connectivity for configuration of your
application. The GPIO interface provides five user-configurable GPIO’s as CMOS input or output ports to be connected to a
customer’s peripheral device. A customer application in which the GPIO interface could be used is one with a monitoring device
connected to the GPIO interface in which the monitoring device triggers an event in the IP stack to establish a TCP or UDP
socket connection or send an email stating that the monitoring device was triggered by high water.

Safety
General Safety
The modem is designed for and intended to be used in fixed and mobile applications. “Fixed” means that the device is physically
secured at one location and is not able to be easily moved to another location. “Mobile” means that the device is designed to be
used in other than fixed locations.
Caution: Maintain a separation distance of at least 20 cm (8 inches) between the transmitter’s antenna
and the body of the user or nearby persons. The Modem is not designed for or intended to be used in
portable applications within 20 cm. (8 inches) of the body of the user.
RF Interference Issues
It is important to follow any special regulations regarding the use of radio equipment due in particular to the possibility of radio
frequency, RF, interference. Please follow the safety advice given below carefully.
●Switch OFF your MultiModem when in an aircraft. The use of cellular telephones in an aircraft may endanger the
operation of the aircraft, disrupt the cellular network and is illegal. Failure to observe this instruction may lead to
suspension or denial of cellular telephone services to the offender, or legal action or both.
● Switch OFF your MultiModem when around gasoline or diesel-fuel pumps and before filling your vehicle with fuel.
● Switch OFF your MultiModem in hospitals and any other place where medical equipment may be in use.
● Respect restrictions on the use of radio equipment in fuel depots, chemical plants or where blasting operations are in
progress.
●There may be a hazard associated with the operation of your MultiModem close to inadequately protected personal
medical devices such as hearing aids and pacemakers. Consult the manufacturers of the medical device to determine
if it is adequately protected.
●Operation of your MultiModem close to other electronic equipment may also cause interference if the equipment is
inadequately protected. Observe any warning signs and manufacturers’ recommendations.
Vehicle Safety
● Do not use your MultiModem while driving.
● Respect national regulations on the use of cellular telephones in vehicles. Road safety always comes first.
● If incorrectly installed in a vehicle, the operation of MultiModem telephone could interfere with the correct functioning of
vehicle electronics. To avoid such problems, be sure that qualified personnel have performed the installation.
Verification of the protection of vehicle electronics should be part of the installation.
●The use of an alert device to operate a vehicle’s lights or horn on public roads is not permitted.
Maintenance of the Wireless MultiModem
Your wireless MultiModem is the product of advanced engineering, design, and craftsmanship and should be treated with care.
The suggestions below will help you to enjoy this product for many years.
● Do not expose the MultiModem to any extreme environment where the temperature or humidi ty is high.
● Do not attempt to disassemble the MultiModem. There are no user serviceable parts inside.
● Do not expose the MultiModem to water, rain, or spilled beverages. It is not waterproof.
● Do not abuse your MultiModem by dropping, knocking, or violently shaking it. Rough handling can damage it.
● Do not place the MultiModem alongside computer discs, credit or travel cards, or other magnetic media. The
information contained on discs or cards may be affected by this device .
● The use of accessories not authorized by Multi-Tech or not compliant with Multi-T ech’s acc ess ory specif ica tion s may
invalidate the warranty of the MultiModem.
● In the unlikely event of a fault in the MultiModem, contact Multi-Tech Technical Support.
Handling Precautions
All devices must be handled with certain precautions to avoid damage due to the accumulation of static charge. Although input
protection circuitry has been incorporated into the devices to minimize the effect of this static build up, proper precautions shou ld
be taken to avoid exposure to electrostatic discharge during handling and mounting.

Power: Indicates presence of DC power when lit.
GPS: If a valid GPS signal has been received, the PWR/GPS LED will blink at 1 second ON, and 0.5 second OFF.
If GPS signal is invalid, the PWR/GPS LED will be on solid.
Indicates the wireless signal strength. In order to verify signal strength, you must use a terminal application such as
HyperTerminal. Refer to Examples of Useful AT Commands in Chapter 3 of this guide.
Back Panel
Your back panel will differ only if you have purchased the optional GP model that has an additional connector for a GPS
antenna. The GPS antenna connector is located between the power connector and the RS-232 connector. The far right
