ROUNDING
Make sure that the
shield of the cable is connected to a
proper ground
, i.e. vehicles structure. This is very important
in order to safely bypass interference from radio equipment
and other environmental noise sources.

The Remote ON/OFF (yellow wire) is a unique feature for the
TT-3026L easyTrack Transceiver. When this wire is left
floating the Transceiver is turned off and when the wire is
shorted to GND (white or orange wire), the Transceiver will
be switched on. This makes it possible for external equipment
to perform remote power control of the TT-3026L easyTrack
Transceiver.
An external relay or solid-state switch can control the power.
