Sensor is not charging with the Medusa or Basic Marport legacy charger

You connected your Pro sensor to a Medusa or Basic Marport charger, but the sensor has not been charged.

Tip: When connecting the sensor to a Medusa or Basic Marport legacy charger, look at the sensor transducer LED to know if it is charging or not.
  • LED is blinking red when compatible and charging.
  • LED is blinking red for 10 sec. then stops, when incompatible.
By default, Pro sensors are not compatible with legacy Marport chargers.
  • Compatibility with legacy Marport chargers is available as an optional feature. It must be activated by Marport sales offices.
If the feature is activated, but the sensor is not charging, it may be because the sensor firmware is not compatible with this feature. In order to be compatible, the sensor firmware version must be F450-02.03.01 or later.
  1. You can check the sensor version from Mosa2:

  2. If the version is lower, ask your local Marport office for an update.
