Plan your MP modem
installation
This section guides you through the decisions you need to
make before you begin the installation.
Where do you want to install your MP modem?
The MP modem can be installed in a vehicle or in an office. The
same installation steps apply with the following exceptions:
• If you are installing the MP modem in a vehicle:
· Use the power harness to connect the MP modem to the
vehicle battery.
· Decide how to set the ignition sense option for powering
the MP modem on and off (that is, depending on the
ignition switch wiring, the MP modem can be turned on
when the engine is started, when the ignition is in
accessory mode, or independently of the ignition).
• If you are installing the MP modem in an office, an AC/DC
adapter is available.
What type of connection(s) do you plan to use?
The MP modem is capable of the following kinds of network
connections:
• Serial
• USB
• Ethernet
• Wireless Access Point via IEEE 802.11b/g (MP 881W only)
Data transfer rates vary, depending on the network, but note
that the highest data rate using a serial connection is
115.2 kbps.
Before deciding which network interface to use, you need to
understand the advantages and disadvantages of each, and
any other implications of using one interface over another.
