Receiver antenna configuration
The 8 channel diversity receiver has, as its name might suggest, two antenna inputs.
The receiver does expect antennas to be connected to both of these antenna connectors, unless
configured otherwise. It is not advisable to leave the receiver configured in diversity mode, and connect
just one antenna.
The ImmersionRCTools application, available from the ImmersionRC website, can be used to configure
the receiver antenna configuration for cases where only a single antenna is used.
Driver/Software Installation on a PC
The Windows software to support the EzUHF may be downloaded from the EzUHF website here:

EzUHF -> EzOSD link
Linking the EzUHF receiver to the EzOSD can create a very powerful combination.
The EzUHF receiver (8 channel version) will periodically inform the EzOSD of the following
measurements:
1. The RSSI (received signal strength) on each of the two antennas
2. The overall signal quality (which includes packet loss information)
3. Frequency error measurement (difference between Tx and Rx frequencies)
4. Error rates per frequency bin
These measurements are in turn downlinked via the telemetry stream, and may be shown on the
antenna tracker LCD display, displayed in the ImmersionPlayer, or shown live using the iPad/iPhone
iTelemetryFPV application.
The on-screen data provides direct feedback to the pilot of any problems with the uplink in real time.
The recorded telemetry stream may be used to diagnose problems after a flight, and can be a powerful
tool for comparing antenna performance, antenna position, etc.
The connector used for this link is the Molex connector named ‘OSD Link’, shown below:
