MOUNTING THE LT1
•
Insert the SD card (see section 1.3.1) if not already inserted
•
Insert the SIM card (Cell models only - see section 1.3.2) if not already inserted
•
Ensure the GPS and telemetry antenna cables are attached to their respective
connectors.
•
Attach the LT1 to the DIN rail by inserting the spring clip into the bottom rail,
applying upward pressure until the top lip slides over the top rail. Release the
pressure so that the LT1 will snap down into position on the DIN rail. The spring
pressure will hold the LT1 in place.
•
Once the power connections have been made to the 4-pin terminal block, insert it into the
LT1 and wait for the LT1 to boot up and obtain GPS and cellular connections, indicated by
the LED status lights.

LED STATUS INDICATORS
Once power is supplied the LT1 will boot up, connect to the telemetry network, and establish a GPS
fix. There are four green LED lights which indicate the status of the system in either of its two
modes (operating and low power). Refer to Appendix A for details of LED status indicators.
