ImmersionRC | EzOSD Manual

Overview
Congratulations on your purchase of an ImmersionRC ‘EzOSD’, the no-nonsense On-Screen Display for
FPV flight.
Features
Crisp text, shadowed to ensure visibility against a summer sky, or a winter evening
No need for a PhD to install and configure
Robust design, reverse polarity protection, overvoltage protection
Firmware upgrades without a PIC programmer, standard USB port (mini-USB B) on-board
Simple, uncluttered display, just the essentials. ‘Which way is home’, and ‘how long can I stay up
here’. Enjoy the view, not the skills of the HUD author.
Warnings for low battery voltage, pack capacity reached, too high, too far, etc.
Periodic Amateur radio callsign broadcast, to comply with FCC regulations
OSD control from a spare servo channel (optional)
Intuitive menu system, with onboard menu buttons. No R/C receiver, or remote control
required to configure, nor fly.
After-flight debriefing, shows a summary of the flight: Max. altitude, max. distance, max. speed,
average speed, distance flown, etc.
5Hz GPS update rate
PAL/NTSC auto-detect
Uncluttered display, enjoy the view, not the OSD clutter!
Robust telemetry downlink, for live Google Earth™ Tracking, or ImmersionRC’s unique Antenna
Tracking system.
Installation
The easiest way to install the EzOSD is when using ImmersionRC cameras and video transmitters. In this
case, standard connectors are used, which are all compatible with those present on the EzOSD. All of
them are keyed, can’t be inserted backwards, or ‘on the wrong pins’ (as is the case with many other
OSDs currently on the market).
Several things to remember when installing the OSD:
1) In the ‘Ez’ Concept, it is the video transmitter which supplies power to the camera, as it generally
does when the OSD is not present. Note that the OSD does NOT supply power to the camera, it simply
passes the Gnd/VCam lines from the transmitter to the camera. This allows the user of 5v or 12v
cameras.
2) The current sensor contains a quiet, cool, switching regulator, which powers the OSD. In applications
where current/voltage sensing is not required, such as a Gas/Glow model, or even a glider, it is possible
to power the OSD directly from a spare connector on the R/C Receiver, without using the sensor board
