PilotAware Rosetta contains all the hardware and software required to operate as an Electronic Conspicuity device. A separate power supply is required (not supplied) for correct operation.

The following picture shows the components of the PilotAware Rosetta.

The Power Lead

It is very important that the 1-metre 20AWG power lead supplied with the PilotAware Rosetta unit is used at all times to maintain the correct voltage (5.2V). Suitable power supplies are described here.

The antenna and aerial

Two antennas are provided. The longer 869.5MHz antenna should be screwed onto the gold SMA connector on the LHS of the unit. The smaller 1090MHz antenna should be screwed onto the gold SMA connector on the RHS of the unit. These are not interchangeable. The antennas must be vertical in normal use ie pointing upwards or downwards. Both antennas are cranked so that this can be achieved if the unit is placed on the dashboard.

Slide off compartment

On the lower end of the Rosetta unit is a slide off compartment which can be removed gently pushing down on the yellow warning triangle and dragging your thumb towards you. Once removed, this gives access to the USB sockets and the two dongles used. Two USB dongles are supplied.

  1. GPS mounted in socket 1 (top left)
  2. Low Power RTLSDR (Software defined Radio tuned for 1090Mhz) in socket 4 (bottom right).

In addition, there is access to the RJ45 Ethernet socket.

MAC Address Label

On the end of the slide off compartment is a label with the unique MAC address of the Rosetta unit.

Six Plastic Suction Cups

On later models of PilotAware Rosetta, a new case was introduced that allows 6 small suctions cups to be fitted directly to the Rosetta case. This allows for easy mounting on smooth plastic or metal surfaces.

Rosetta Lights 

On the main Rosetta unit and the GPS dongle, there are lights that can be used to ensure that all is working well. These can also be used for the diagnosis of faults.

L1 This is located on the left-hand side of the Rosetta unit under the L1 sign on the label. 
L2 This is located on the left-hand side of the Rosetta unit under the L2 sign on the label.
L3 This is located on the motherboard inside above and left of the power connector.
L4 This is located on the motherboard inside above and left of the power connector.
L5 This is located on the underside of the GPS Dongle labelled Power
L6 This is located on the underside of the GPS Dongle labelled PPS

The operation of these lights in normal operation is described in the troubleshooting section. For correct operation, the antennas and GPS must have an uninterrupted view of the sky.
