2.1.2 “X” Relay This is controlled via SMS or GPRS messages :W,X,1 Selects NO :W,X,0 Selects NC (by default the relay is in this state) (Max load on relay contacts = 1AMP resistive) It is possible to use this relay to disable a vehicle. To interrupt the fuel pump, disconnect the supply to the pump and connect it to the tracker on Pin 13.
2.1.4 Static Alarm The Static Alarm is designed as a simple multi function alarm monitor. N.B. For correct Static Alarm functionality the Normally closed Switch must be connected to ground, otherwise the unit will always be in a static condition. In the above example both the normally closed and the normally open switch are connected to switches to ground, this is the simplest configuration.
2.1.5 Spare IO's Pins 11 and 13 (also 15 if unused for external alarm input) on the tracker can be used for monitoring the status of external devices such as switches or sensors. These devices have to operate at 12V. For example: Battery monitoring, or door switch.
2.1.7 Power Supply For correct operation the tracker needs to be connected to the vehicles battery supply (either directly or through existing wiring e.g. back of stereo) It is recommended that the +ve supply of the ignition is wired through a 3Amp fuse to protect the vehicle wiring.
