Multi-Tech Systems, Inc. MultiModem rCell User Guide 7
Chapter 1 – Product Overview
This User Guide describes the MultiModem® rCell intelligent wireless routers with an Ethernet II interface. You
can configure the MultiModem rCell Router for one of three connectivity modes: always-on, wake-up on ring, or
dial-on demand.
The always-on network connection automatically establishes a wireless data connection and allows for around the
clock surveillance, monitoring or real time data acquisition of any remote Ethernet device such as a Web camera.
If the data link is dropped due to poor reception or a complete loss of service, this feature automatically re-
establishes the data link.
The wake-up on ring configuration allows the router to “wake up” and initiate a connection when it detects an
incoming ring. For security reasons, you can setup the router to wake up based on a particular caller ID number.
This configuration is ideal for reducing the costs associated with the modem being online and available 24/7.
When configured for dial-on demand, the router only accesses the Internet when data is present. This
configuration is ideal for sharing Internet access among networked computers.

Safety Warnings
Ethernet Ports Caution
The Ethernet ports are not designed to be connected to a Public Telecommunication Network or used outside the
building.
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 should be taken to avoid exposure to electrostatic discharge during handling and
mounting.
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 router is not designed for, nor intended to be, used in 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 this safety advice:
●Switch OFF your Wireless 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 Wireless MultiModem when around gasoline or diesel-fuel pumps and before filling your
vehicle with fuel.
●Switch OFF your Wireless 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 Wireless 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 Wireless 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 Router while driving, unless equipped with a correctly installed vehicle kit allowing ‘Hands-
Free’ Operation.
●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 router 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.

Chapter 2 – Installing the Router
Inserting the SIM Card into Holder, for GSM Network Access
The router 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, do the following:
1. Using a small Phillips screwdriver, remove the two SIM door screws and remove the SIM door.
Note: When changing a SIM, ensure that power is removed from the unit.
2. Insert the SIM card into the card holder. The above graphic illustrates the correct SIM card orientation.
3. Verify that the SIM card fits into the holder properly and then replace the cover.
Making the Connection
MTCBA-XX-EN2 MTCBA-XX-EN2-GP (GPS antenna)
1. Connect a suitable antenna to the SMA connector (see antenna specifications in Chapter 1)
2. Optional: If you have the GPS version, connect a suitable GPS antenna to the GPS connector. Ensure that
when you position the GPS antenna, the antenna can see the sky to locate the satellites for accurate values.
3. Using an Ethernet cable, connect one end of the cable to the ETHERNET connector on the back of the router
and the other end to your computer either directly or through a switch or hub.
4. If you are connecting a customer’s serial legacy device to the router, connect the serial, RS-232 cable from the
customer’s device to the RS232 connector on the back of the router.
5. Depending on the power source, connect either the power supply module with the appropriate blade or the
optional DC power cable. If you are using the power supply module, remove the protective shipping cover.
Attach the appropriate interchangeable blade piece to the power supply module.

Chapter 2 – Installing the Router

6. Screw on the power lead from the power supply module into the power connection on the router. Plug the
power supply into your power source.
Using Optional Direct DC Power
1. Screw-on the DC power cable to the power connector on the router.
2. Then attach the two wires at the other end of the DC power cable to a DC fuse/terminal block in which you
are mounting the router.
3. Connect the red wire to the "+" (positive) terminal and the black wire to the "–" (negative) terminal. Be sure
the GND connection is correct.
Warning: Over-voltage protection is provided on the device. To ensure complete protection, you may want to
add additional filtering to the DC input.
Notes:
●For an application involving a battery: you can use permanent “+” or key-switched “+” source. Connect the
power supply to its source (for example, in a mobile situation, to the DC fuse/terminal block).
●The POWER LED. The POWER LED lights after power-up.
●The Status LED is a solid ON when the router is booting up, saving a configuration, or updating firmware.
When the Status LED begins to blink, the router is ready.
Using the Reset Button
Press and hold in the Reset button until the Status Light goes out. Then release the button. This sets the username
and password back to admin and admin, as well as sets the IP address to the default of 192.168.2.1.
Powering Down and Resetting Hardware for MTCBA-C1 Router
Before you turn off power to the router, and before you reset the hardware, it is recommended you complete the following
sequence.
The shutdown sequence informs the network that the mobile station is going offline, and saves critical data to the module‘s
non-volatile memory (flash).
1. Issue the following command:
AT+CFUN=0 (issue this command)
2. Wait for this response from the modem
+WIND:10 ()
You can now power off the router or reset it.
If you do not see the +WIND:10 response, you may need to activate the unsolicited message by using the
command AT+WUSLMSK=00020000,0
