Product introduction
The system include sensors, repeater and monitor with can-bus port. It is used to monitor the pressure and temperature data of the tires. After collecting the pressure and temperature data, the sensors send the data to the repeater and monitor by wireless RF, the repeater send all data to the monitor at the same time. The monitor send tire data to CAN-BUS network and display all tire data in his screen at the same time, The instrument or other display device collect all tire data and display from can-bus network. When the pressure or temperature over or under warning valve value, the instrument will warn automatically to remind the users pay attention to the tires' situation.System drawings
Display Installation
Having a slot opening in the center console in the appropriate location according to the size of the receiver ; the receiver power cord and car power supply line corresponding connection; the embedded display into, so completely consistent with the stuck. See below
Applications
Applicable to the tire pressure under 14Bar/203PSI
Main display interface
- tire mode
- Receiver working status
- Data up and down checking
System Setting Method
Note: System Preset in factory,if correct installation and normal use, do not have to operate the following settings.Enter system setting mode
When it is under normal working status, long press key for 3 seconds, enter the first setting, the screen will display "P1", Shortly press key 1 second each time, number plus 1, it will switch from P1 to P5 circularly. Press key to enter setting.Press key or no press any key approx. 10 minutes, it will exit to normal working status.
