    Through the accessory  Serial Port Expander we have the ability to read up to 3 Technoton sensors that use RS232 communication.


    1.- Configure the sensor according to the DCT guide available in this link: Fuel Level Sensor
    It is important to configure only the sensor, please, do not send commands to the Syrus yet.
    2.- Check the Syrus’s serial port Baud rate (It should be 115200).

    If you are not sure about the Baud Rate, you can send this command to the Syrus: >QXABR<

    If the Baud Rate is different from 115200 you can use the command >SXABR115200<

    Please, consult the Syrus Manual for more detail about the commands.

    3.- Check for the sensor and Serial Port Expander Installation (See image below).


    NOTE: Some Syrus Model (Like 1645) Uses a brown cable color for the TX signal.

    4.- Configure Syrus to communicate with the Serial port Expander:

    The next commands are specifically for 2 sensor connected to the serial Expander. If you want to add one more sensor change the second command fot this one >SXARMCDDDUUU<


    5.- Check for the correct communication between the Syrus and its accessories.

    Use the next command to check the serial expoander: >QXARM0<

    This is an example of a good answer: >RXARM01,11,11,0,11,0<

    Use the next comand to read the Technoton in the Serial port 1: >QXATFE1<

    Use the next comand to read the Technoton in the Serial port 2: >QXATFE2<

    Use the next comand to read the Technoton in the Serial port 3: >QXATFE3<

    This is an example of a good answer in the port 1:  >RXATFE11,2707,36,149<


    6.- Be sure that Syrus report the data to Pegasus:

    Add this TAG to your Extended Tag event format: FE


    Check the raw data to see the information of the sensors.

    7.- Make sure to configure your vehicle’s fuel parameters in Pegasus.

    You are done!
