5 Harness Installation Instructions
5.1 Harness Outputs Installation Specifications
5.1.1 General
The following information is common for all the outputs:
All Outputs are Open Collector type and can sink up to 300 mA continuous.
External devices (not OEM) that consume more than 300mA should be powered by a relay.
In such cases, the output implementation requires an external relay.
The outputs can be activated or deactivated from the control center using the OTA command.
5.1.2 Relay Pin-Out
A relay is utilized to serve as an adaptor between the harness output and a device in the
vehicle (immobilizer, siren, etc.). The following figure shows the pin-out location of the relay.
The pin numbers are also printed on the Relay itself.
Figure 16: Relay Pin-Out
The relay figure and the pins numbers are used when describing harness outputs installations.
5.1.3 LED Output
The harness LED green wire is connected to the CR unit pin no. 2. The LED itself should be
connected to the LED wire and vehicle Battery. The LED provides an indication of system
status. A full description of LED indications in the CR unit is presented below.
The LED output can be used as general purpose open collector output, if configured accordingly.
The LED output involves a sophisticated blinking pattern which provides monitoring status
of both GPS and GSM status. The blinking pattern is constructed of repeated cycles of two
blinking zones each. The first zone represents GSM functionality and the second zone,
GPS functionality.
Each zone lasts for 3 seconds with a 1-second LED off interval between them. A
5 second LED off interval separates each cycle.
