Crimp terminals
If suitable terminal connection points are available on the vehicle for power and
ignition sense, then using automotive crimp terminals is recommended. When
using crimp terminals, do not leave bare wire exposed. Do not use a crimp
terminal for more than one wire unless it is designed for that purpose.
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.
•
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.
Serial connector (DB9) pinouts
The MP modem is configured as DCE (Data Communications Equipment) and
uses the standard RS232 pin designations: Pinouts for an RS232 male DB9 serial
cable (left) that connects to the MP modem's female DB9 serial connector (right).
Note that the two figures' pinouts are mirror images of each other, since they plug
together.
