The EzUHF 8 channel diversity receiver  is a compact 8CH receiver for use with the ImmersionRC EzUHF system. It can provide long range control of your FPV model with the robust interference rejection that diversity antennas provide.

Compact Long-Range R/C Receiver 
Ideal companion to the EzUHF transmitter. Sensitive receiver, with twin antenna inputs, in a diversity configuration. Fits the most slender of glider fuselages.

Interference Rejection
Each antenna input contains a 7-section ceramic low-pass filter, which silences interference from nearby high-power video transmitters on 900/1.2/2.4/… bands. Attenuation at 900MHz is > 40dB, at 2.4GHz > 75dB, right at the antenna input.

Mikrokopter Compatibility
Programmable MK mode, emits raw PPM on a chosen channel. The EzUHF Rx is an ideal receiver to use on Mikrokopters used for longer-range flights.

The ceramic filtering is a huge benefit on a small MK frame, which has a Video Tx antenna nearby.

EzLink connection to an EzOSD 
No more guessing! the EzLink cable connects the EzUHF to an EzOSD on-screen display. All critical parameters are sent to the OSD, which displays them live on the display and downlinks them along with the antenna-tracking telemetry.

A ground-based EzAntennaTracker displays the parameters on its LCD display, and the ImmersionPlayer application plots them on its Google-Earthâ„¢ overlay.

* Why ‘Bi-directional ready’?: The EzUHF Transmitter is a full transceiver, i.e. it includes both transmitter, and receiver hardware. The 8 Channel receiver is also a transceiver, so both are capable of bi-directional communications. Firmware to take advantage of these capabilities will available in the near future, both are field-upgradable using a std. USB cable.

Arbitary Channel Mapping

Using the ImmersionRC Tools, the servo outputs of the EzUHF 8 channel Rx may be arbitrarily remapped to suit the target model.

Multicopter wiring may be greatly simplified using a single PPM cable, easily configured using the tools. Need PWM outputs to drive Pan/Tilt servos?, no problem using the tools.

 

 

Uplink Status (UPSTAT)

All uplink status is available in the single-cable PPM stream for use by supported OSDs. The XuGong v2/Pro, or the upcoming XuGong Vortex both take advantage of this method to show critical uplink status on-screen.

The received signal strength (RSSI) of each of the receiver’s antennas, along with the link quality, are captured by the OSD, and displayed with appropriate alarms to indicate marginal conditions.

NOTE: EzUHF Firmware v1.51 or later required to support single-cable UPSTAT.
