Powering Up the Rosetta-FX Electronic Conspicuity Device

This section of the Knowledgebase will walk you through the various options for powering up the FX device.

Overview of Power Inputs.

For convenience of installation, the Rosetta-FX Device can be powered through ONE of three different power inputs.

USB-C Power Input

  • The USB-C port provides a convenient way to power the device with a standard USB-C 5V input. This method is suitable for testing the device or for operations where an aircraft has no power bus but USB power is readily available from a 5V Power Bank such as an ANKER Power Bank. Please note the FX USB-C port must not be used to supply power to other devices.

Molex-SL Power Input

  • This is the recommended option for a more permanent secure installation. This option accepts a wider 9-30V connection from your aircraft (12-24V) bus bar. The cable provided includes a 2A quick blow fuse and a keyed, locking Molex-SL connector for a secure connection.

RJ45 Power/Data Input

  • The FX can also receive both power and data from an existing FLARM installation using the standard port pinout. The FX RJ45 port is also compatible with RJ12 cables, offering cable flexibility. An RJ12 cable are provided with the FX.

Steps for Powering Up the Device.

Using the USB-C for Power

  • Insert the USB-C cable into the designated USB port on the FX device.
  • Connect the other end to a 5V USB power source such as an ANKER Power Bank.

Using the Molex-SL for Power

  • Attach the spade connectors to a fused BUS within the 9-30V range. FX is reverse-polarity protected; however, please ensure the polarity is correct when installing.
  • Securely connect the Molex-SL cable to the device’s Molex-SL port. Please note that the keyed Molex-SL connector has a simple top latch that needs to be depressed to remove the connector.

Using RJ12 cable for Power and Data from FLARM

  • If you are connecting the Rosetta FX in series with your existing FLARM device then the power and GPS signals will be supplied from the FLARM Device to the FX.
  • Check that your existing FLARM unit is working and has the latest software installed.
  • Turn the power to the FLARM off.
  • Disconnect the existing cable from the FLARM box to the FLARM display at the FLARM box end and connect this to the output port of the FX.
  • Then, using the RJ12 cable supplied connect the output of the FLARM box to the input port of the FX. This connection will then provide power and data to the FX which is now installed in series between the FLARM and the FLARM display.
  • Important Notes:
  • Double-check the voltage range of your chosen power source before connecting to avoid any damage.
  • Do not attempt to power the FX through the power bank and your aircraft bus.
  • Refer to the FLARM manual for detailed instructions and safety information.
  • Do not over-tightly wrap or strain any cables, as this can cause damage over time and may result in the failure of the cable or device.
  • If you are in any doubt regarding your installation consult a qualified engineer or your inspector or contact support@pilotAware.com
