Programming

The initiator is a handheld tool that assists the service technician during installation of the SmarTire system. The initiator is designed to interact with a high pressure sensor to provoke a data transmission or to place the sensor in a different state. The initiator assists the technician in programming newly installed sensors and in verifying the correct installation of these sensors.

Initiator Functions

Button

Function

Initiate

This function is used after the sensors are installed to confirm whether the sensor positions were properly programmed in the receiver. Pressing this button while holding the initiator against the tire sidewall adjacent to the sensor causes the sensor to transmit its ID, tire pressure and temperature data.

De-energize

This function should only be used when the sensors are taken out of the tire and need to be shipped back to the supplier. Pressing this button while holding initiator next to the side of the sensor causes it to stop transmitting.

Learn

This function is used to provoke a Learn transmission from the sensor in order to program the receiver. Pressing this button while holding the initiator against the tire sidewall adjacent to the sensor causes it to transmit its Learn signal.
