Jetibox

MEX is able to simulate a Jetibox to read telemetry from Legacy Jeti devices, the following steps need to be taken:

  1. Go to Devices menu → Jetibox panel.

    Enable it and select a SCI Port, in this example SCI A is selected:

    Jetibox - Devices configuration

  2. Go to Input/Output menu → Serial panel.

    Configure the serial port (the one selected in step 1) as follows:

    • Baudrate: 9800
    • Length: 8
    • Stop: 2 stop bits
    • Parity: Odd
    • Use address mode: Enabled

    Jetibox - Serial configuration

    Note

    The serial port will be completely reserved for this, so it cannot be used for any other purpose and the I/O Setup configuration affecting it will be ignored.

  3. Go to Input/Output menu → I/O Setup panel.

    Link the specific JETI box consumer to the serial port that has been configured in step 2:

    Jetibox - I/O Setup configuration

  4. Configure the Jetibox I/O consumer to retrieve the data. Click on the configuration button ():

    Jetibox - JETI box Consumer configuration

Below is an example of the custom messages needed to read the Actual Voltage from a Jeti MasterSpin 220 (use Big endian in all messages):
