Hardware Installation of the PinPoint X
Rev 3.0B Feb.08 23
Connecting to Power
Your PinPoint X can be used with either DC, available in most
automobiles, or 110 AC, standard US wall power, with the
appropriate power adapter. DC cables and AC adapters are
available as optional accessories in addition to the one
included with your PinPoint X.
Note: When using a DC power
source (such as a car battery or
solar cell), Sierra Wireless
recommends placing a fuse (1-2
Amp) on the line close to the
power source to protect your
power source from possible
surges due to shorts or other line
issues. The DC power cable positive lead should be connected to the
battery or power source positive terminal. The power cable
negative lead should be connected to the battery or power
source negative terminal.
The PinPoint X has an internal polysilicon circuit breaker that
opens at 0.5 to 1.0 amps of current.
If you wish to use the Standby Ignition Sense (SISE) feature of
your PinPoint X, the white wire of the three wire DC power
cable should be used to connect to your ignition. When SISE is
enabled in the modem and the ignition sense connector is
wired to your vehicle, the ignition sense will provide a link to
the modem to enable it to enter a low‐power, standby mode
when your vehicle is turned off and power up more quickly
when the ignition is started.

The Ethernet port of your PinPoint X can be connected directly
to a computer or other Ethernet device with either a cross‐over
cable or a straight‐through cable. The Ethernet port on the
PinPoint X is auto‐sensing and will auto‐detect the speed of the
connecting device for 100baseTX or 10baseT. If you are
