¶ Configuration
- On the "RS-232/RS-485" tab set up the sensor on the digital interface
- For
Pressure Pro(old model) set "Baud rate" =38400 - For
Pressure Pro PULSEset "Baud rate" =9600
- On the "Protocol Settings" tab:
- set "Data transfer protocol version" =
FLEX 2.0(or higher) - select the number of transmitted sensors.
- set "Data transfer protocol version" =
¶ Connection
For the kit to work, it is necessary to connect the device and the sensor via the RS-232 interface.
It should be remembered, that RS-232 interface has cross-connection:
¶ Work Features
¶ Wheel number
When working with Pressure Pro (old model) and Pressure Pro PULSE there is a difference in the formation of the wheel number.
¶ Pressure Pro
Wheel numbers from Pressure Pro are broadcast directly from the display to the GPS server without modification.
¶ Pressure Pro PULSE
Our devices support A и B units for Pressure Pro PULSE. For A unit wheel numbers will be in the range 1 - 127, for B unit: 128 - 255.
Numbering of the wheels is made according to the same principle as in the Pressure Pro PULSE module itself, only taking into account that:
- most significant bit of the numbering in the device determines the unit, specifically: 0 - A, 1 - B;
- next 3 bits define the axis number;
- remaining least significant 4 bits determine the wheel number.
Those, like this:
| Bit numbers | 7 | 6 5 4 | 3 2 1 0 | |||||
| Assignment | Unit:0 - "A"1 - "B" |
Axis:0 ... 7 |
Wheel number:0 ... 15 |
|||||
Example:
-
If the device transmits the wheel number
0x54- this is information about the right (4th) wheel on the 5th axle for A unit. -
If the device transmits the wheel number
0xD4- this is information about the right (4th) wheel on the 5th axle, but for the B unit.
Please note that in the telemetry of the Configurator (and on most GPS servers) these wheel number values will be displayed in decimal form,
84(0x54),212(0xD4)
¶ Data set
When working with Pressure Pro, only wheel position, pressure and temperature parameters are transmitted.
However, device will generate out-of-order messages when it receives the appropriate information from the pressure control system.
¶ Pressure Pro
| HEX code | DEC code | Description |
|---|---|---|
| 0x2524 | 9508 | Tyre pressure drop below the first threshold (presspro: tire pressure drop below threshold by 12.5%) |
| 0x2525 | 9509 | Tyre pressure drop below the second threshold (presspro: tire pressure drop below threshold by 25%) |
| 0x2521 | 9505 | Tyre pressure sensor: critical alarm (presspro: low sensor battery) |
¶ Pressure Pro PULSE
| HEX code | DEC code | Description |
|---|---|---|
| 0x2520 | 9504 | Tyre pressure monitor: system alarm |
| 0x2521 | 9505 | Tyre pressure sensor: critical alarm (presspro: Missing / LowBatt / Delta-Pressure alarm) |
| 0x2522 | 9506 | Tyre temperature rise above the first threshold (presspro: Over-Temp) |
| 0x2524 | 9508 | Tyre pressure drop below the first threshold (presspro: Under-Pressure) |
| 0x2525 | 9509 | Tyre pressure drop below the second threshold (presspro: Extreme-Under-Pressure) |
| 0x2526 | 9510 | Tyre pressure rise above the set threshold (presspro: Over-Pressure) |
