Office installation
Use the AC/DC adapter available from Sierra Wireless to
connect the power harness to a standard outlet.
Step 4 — Connect the MP modem to
computer cable
The MP modem connects to:
• A computer through a USB, Ethernet, or serial port
• Other optional devices through the DB15HD I/O connector
Note: Do not connect the MP modem to the computer until you have
installed the software.
The MP modem connects to a computer using:
• A USB cable (with a Type A connector on the computer
end and a Type B connector on the MP modem end). The
maximum of the USB cable is 5.5 m (18 feet). These cables
are readily available from many suppliers.
• An Ethernet cable with RJ ‐ 45 connectors. The type of cable
you use affects the performance of the MP modem. The
minimum requirement for the Ethernet cable is an
unshielded twisted pair (UTP) cable, category 3 or 4. For
better performance, use a shielded, category 5 cable. The
theoretical maximum length is 100 m (328 feet).
You can connect the MP modem Ethernet port directly to a
computer or other Ethernet device with either a cross ‐ over
or a straight ‐ through cable.
Note: 5.5-meter cable part
number: 6000083.
• A serial cable (with a DB9 connector on the MP modem
end). The maximum length of the serial cable is 5.5 m
(18 feet). Sierra Wireless sells suitable serial cables in 5 ‐
meter (16 ‐ feet) lengths.
