Introduction
This guide shows you the cable connections and the SIM card placement for your
MVPGSM unit. See your User Guide included on the CD for more information.
Safety Warnings
Lithium Battery Caution
A lithium battery on the board provides backup power for the timekeeping
capability. The battery has an estimated life expectancy of ten years.
When the battery starts to weaken, the date and time may be incorrect. If the
battery fails, the board must be sent back to Multi-Tech Systems for battery
replacement.
Warning: There is danger of explosion if the battery is incorrectly replaced.
Ethernet Ports Caution
Caution: The Ethernet ports (WAN) and console ports are not designed to
be connected to a Public Telecommunication network.
Safety Warnings Wireless
The modem is designed for and intended to be used in fixed applications. “Fixed”
means that the device is physically secured at one location and is not able to be
easily moved to another location.
Caution: A separation distance of at least 20 cm (8 inches) must be
maintained between the transmitter’s antenna and the body of the user or
nearby persons. This product 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 MultiVOIP GSM 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 MultiVOIP GSM when around gasoline or diesel-fuel
pumps and before filling your vehicle with fuel.
•Switch OFF your MultiVOIP GSM 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 MultiVOIP
GSM 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 MVPGSM close to other electronic equipment may also
cause interference if the equipment is inadequately protected. Observe any
warning signs and manufacturers’ recommendations.

Cable Hookups for MVPGSM-2
•Connect a power cord to the transformer and to a live AC outlet, and then
attach the barrel connector to the back of the MultiVOIP GSM as shown in the
figure above.
•Connect the MultiVOIP GSM to a PC by using a RJ-45 (male) to DB-9
(female) cable. Plug the RJ-45 end of the cable into the CONSOLE port of the
MultiVOIP GSM and the other end into the PC serial port.
•Connect a network cable to the WAN connector on the back of the
MultiVOIP GSM. Connect the other end of the cable to your network.
•Attach an antenna to both channel connectors on either side of the
MultiVOIP GSM. When mounting these antennas, a minimum of 20 cm (8
in.) must be maintained between each transmitting antenna.
Power-Up
Turn on power to the MultiVOIP GSM by placing the ON/OFF switch on the
back panel to the ON position. Wait for the Boot LED on the MultiVOIP GSM to
go off before proceeding. This will take about one minute.
Configuration
When the cabling connections above have been made, go to the installation
chapter of the User Guide (on your MultiVOIP GSM CD) for detailed
instructions about configuration.

GSM Instructions
Step 1 – Activate Your Wireless Account
Please see the wireless account Activation Notices located on the CD if you need
to activate your account.
Phone Numbers: Each channel will have its own unique phone number. The
phone number may simply be given to you by your wireless service provider or it
may be on the SIM card or both. Wireless provider implementations may vary.
Step 2 – Installing the SIM Cards
The MultiVOIP GSM requires the power supply connection to begin operation.
It also requires a SIM card (Subscriber Identity Module) to operate on a GSM
network. To install the SIM cards, do the following:
1. Remove the three highlighted screws from the back as shown below.
2. Slide the cover forward and up to remove it.
3. Insert the SIM cards into the units at the front of the MVPGSM.
4. Verify that the SIM cards fit into their holders properly and then replace
the cover.
Step 3 – Signal Strength
Before final placement or mounting, ensure that the wireless signal strength is
strong enough for the chosen area. To find your signal strength, look at the
LED indicators on the front panel. If the first indicator is lit (“one bar”), there is
sufficient signal strength for proper operation. If two or three are lit (two or
three “bars”), then there is good signal strength and operation will not be
impaired.

mounting. Make sure your signal strength is adequate before permanently
attaching the MVPGSM to a surface.
