Technoton DUT-E 232 Fuel Sensor

Technoton

This section explains the functionality of the Technoton DUT-E 232 fuel sensor with Antares 4G.

The DUT-E 232 fuel level sensor is designed for precise fuel level measurement in vehicle tanks and fixed-installation tanks. It can be used as part of a fuel monitoring system or as a replacement for a vehicle's standard fuel meter.

The sensor calculates fuel level internally and sends data over RS232 to Antares 4G. The received information can be:

  • Reported to Pegasus Gateway using the FF extended tag in event reports.
  • Queried directly through the XATF command family.

Setting Up Antares 4G​

Antares 4G communicates with the Technoton sensor through its serial port at 19200 bps, 8N1.

To use the sensor, enable Technoton communication mode with XATF - Technoton Fuel Sensor.

In this mode:

  • The serial console is disabled.
  • Configuration commands are not accepted through the serial port.
  • Configuration commands can still be sent over the air.

To exit Technoton mode from serial, send the escape message EXIT_COMMDATA as a single packet (for example, with a terminal program).

You can also disable Technoton mode over the air using XATF - Technoton Fuel Sensor.

Verify Technoton State​

After enabling Technoton mode, query the sensor state:

>QXATFF<

Example response:

>RXATFF1,2571,24,0<

In this response, the first value 1 indicates the Technoton sensor is connected.

For details about fields and status values, see XATF - Technoton Fuel Sensor.

Data Access and Reporting​

Technoton data can be consumed in two ways:

For signal behavior and definitions, see Signal List.

Relevant Technoton signals:

  • G35 - Excessive fuel consumption detected by thresholds
  • G36 - Technoton fuel sensor connected
  • G37 - Fuelling event detected by thresholds
