4. iagnostics Q A Q The OSD is taking along time to acquire satellites or is not very precise when flying A This is acommon problem in our hobby The GPS receiver is extremely sensitive and is generally placed in close proximity to a powerful video transmitter To solve this keep the GPS as far from the video transmitter as possible 2 Speed Altitude not accurate when flying 3D The GPS antenna is directional and is similar to the patch antennas that we use commonly for video When throwing a plane around the sky diving rapidly flying inverted etc this directional antenna may well not be facing towards the satellites which provide its position During these times it is normal for the GPS readout especially speed and altitude to be in precise When level flight is returned the readings will correct themselves ImmersionRC EZOSD Manual w Thank You Thank you for purchasing this ImmersionRC product We take great pride in the design of our products and hope that they give you as much pleasure as they have given us Please don t hesitate to feed back any comments suggestions complaints to us we do listen and any feedback will help in perfecting our products in the future Now what are you waiting for Go Fly T Tad Salih DST LZE IS D FiLM Bi i T L BATL IL 4u CUR B BA G 3ZnAh ImmersionRC EZOSD Manual e

9. 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 ImmersionRC EZOSD Manual a to power the OSD directly from a spare connector on the R C Receiver without using the sensor board at all A wiring diagram for this configuration is shown below 3 The telemetry downlink from the EzOSD uses the AUDR Right channel of a stereo audio pair signal In the case of using ImmersionRC A V transmitters which transmit high bandwidth stereo audio the standard cabling will connect this signal correctly In the case that 3 Party video transmitters are used possibly with mono audio ensure that the AUDR signal from the OSD is correctly routed to the transmitter s audio input pin 1 Installation using an ImmersionRC camera and transmitter 1 Connect the current sensor between the LiPo and the ESC 2 Hook the 4 pin cable between the current sensor and the OSD it is keyed
