Appendix B – IX101 Electrical
Installation
Antenna Connections:
Two antenna cables must be connected to the IX-101. The GPS cable is connected to
the small gold (SMA) connector in the right side of the front panel. The GSM/GPRS
phone antenna cable with the second small (SMA) connector must be connected to the
small gold connector in the left side of the front panel.
POWER Connections:
There are four wires which must be connected for a minimally configured IX module can
function. The supplied cables are color coded to aid in proper installation.
The BLACK wire is the ground and should be connected to the negative battery voltage.
This is normally, but not always, the chassis of the equipment. If the equipment has a
master disconnect switch on the negative side this ground connection should be
between the battery and that switch.
The RED wire is the continuous power wire. It should be connected to the positive side
of the battery power through a 3 to 5 amp fuse. It must not be switched by the ignition,
a master disconnect switch, nor any other switched apparatus. This power is used to
run the real-time clock which enables the unit to wake at scheduled intervals. It also
maintains the GPS data to allow quicker position determination when the equipment
starts.
The GREEN wires provide the switched power ("ignition") signal. They are used to
indicate that the equipment has started operation (or is running). One of the GREEN
wires should be connected to a signal which is grounded (or open circuit) when the
equipment is "OFF", and it should be at the battery voltage (greater than 7 volts) when
the equipment is running. The other GREEN wire should be connected to chassis
ground.
DIGITAL INPUTS:
Both digital inputs on the IX module are electrically identical. The IX module reports the
input as "OFF" if the input is switched to below approximately one volt. It reports "ON"
when it is switched above about five volts.
