  SELECT THE RIGHT SOCKET FOR EACH SENSOR.

  Possible sockets for this sensor are:
  - XTR_SOCKET_E           _________
                          |---------|
                          | A  B  C |
                          |_D__E__F_|


  Example: a 5TM sensor on socket A will be
  [Sensor Class] [Sensor Name] [Selected socket]
  Decagon_5TM    mySensor      (XTR_SOCKET_A);

  Refer to the technical guide for information about possible combinations.
