Chapter 1 – Product Description and Specifications
Multi-Tech Systems, Inc. MultiModem rCell User Guide 5
Chapter 1 – Introduction and Product
Description
This User Guide describes the MultiModem® rCell, Intelligent Wireless Router with an Ethernet 2 interface. The MultiModem
rCell Router is configured 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 in the
event of poor reception or a complete loss of service, it will automatically re-establish 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 PCs.

Safety Warnings
Ethernet Ports Caution
The Ethernet ports are not designed to be connected to a Public Telecommunication Network or used outside the building.
12B12BHandling 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 the safety advice given below carefully.
●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.
