Radio Setup for Head Tracking

Typical radio setup

General requirement for radio to support head tracking: Your RC radio must be able to selectively assign trainer functions for the higher channels (ch5-8) in order to work. Many radios can do selective assignment but only on the 4 primary controls. Read your RC radio manual 1st before requesting support for your radio.

Specific radio setup

Futaba

- Enter TRAINER menu and assign desired head tracking channels to FUNC (must be set on FUNC). Default is CH 5//6.
- Individual servo direction can be set in REVERSE menu

Note: trainer toggle must be enabled. toggle is spring actuated and needs to be held in place (personally I put a piece of plastic in the gap behind the switch to hold it on - others use elastic bands).

Tunigy 9X

Note: The Turnigy 9X radio requires the (Cab RC 009) PS/2 to 3.5mm data cable accessory. 
If you have made your own cable and can't get the head tracking to work, start your troubleshooting with the home made cable. 

1) Turn everything off, remove the Headset plug from the back of the radio (leave PS/2 plug inserted to bottom of headset).
2) Turn on radio and set trainer STATE to INH and ch5, ch6 to NOR
3) Hit the MENU button to exit (don't press the EXIT button or the settings won't be saved)
4) exit the menu and enter the DISPLAY (servo test screen). At this point all the bars will be blank
5) The HT switch is spring loaded so grab some elastic bands, tape or velcro and hold the spring loaded toggle switch in the on position.
5) Power the goggles with the battery
6) Connect the trainer pin to the Radio
7) Move the goggles around a whole bunch to trigger the auto disengage (2 beeps).
8) Place the goggles down gently on the table in front of you
9) Press and hold the HT reset button until you hear the single beep that indicates the HT is in active mode
10) gently move the goggles without excessive motion - you can see the servo bars tracking the headset.

* Adjusting the servo center point: Due to the design of servos, the native center point may vary from servo to servo. The Turnigy 9X cannot compensate so the center offset must be adjusted in HT menu as follows:
- Set pan tilt brackets onto servo spur as close to center as possible.
- Enter HT menu (described above) 
- On 1 long beep, press HT button
- Head tracker will now be active and can control pan tilt. Aim camera in desired center position and re-press HT button.
- Headset will beep 2X to confirm adjusted center offset
- Disconnect battery and restart before using.
Note: center offset is limited to +/- 20 degrees (thus the necessity to setup servos as close to center as possible before adjusting). If there is no 2X beep after confirming offset, the offset adjust was unsuccessful.

Patrick's Contribution:

Ok , first thing is you want to put the HT back to stock settings .
Hold the rocker switch down and plug in the battery to the goggles (release rocker switch straight away)
Have the Trinity menu in front of you and follow the beeps through the menu till you hear 6 short beeps. quick press the rocker switch to confirm ..it should beep to confirm.
Turn off goggles for now.

Next..

 Radio , you really want it in Airplane mode , so there are no unwanted helicopter mixes going on to stuff things up.
Once you change it to Airplane mode then you can set up like this.
BTW you don't need the rubber-bands to hold the trainer switch at all doing it this way.

1) Turn everything off, remove the Headset plug from the back of the radio (leave PS/2 plug inserted to bottom of headset).
2) Turn on radio and set trainer STATE to INH and ch5(gyro), ch6(flap) to NOR.
AIL,ELE,THR,RUD, should all be off.
3) Hit the MENU button to exit (don't press the EXIT button or the settings won't be saved)
4) exit the menu and enter the DISPLAY (servo test screen). At this point all the bars will be blank
5) plug your Pan and Tilt servos into the corresponding socket on you RC Receiver (pan is ch5 , tilt is ch6 ) 
6) Power the goggles with the battery.
7) Connect the trainer pin to the Radio.
8) Trinity HT starts up in pause mode , so now you need to turn it on, hold the rocker switch down till it beeps , activating the HT.
9) gently move the goggles without excessive motion - you can see the servo bars tracking the headset and your pan/tilt mount should be moving too.
10) if the motion is back to front , you need to change it in the HT menu in the goggles following the Trinity HT manual to correct directions.

Hope this helps , and this is the exact set-up I use in mine (same radio and goggles with Trinity , so I know it works )

Spektrum DX7s and DX8

Enter trainer setup menu of your DX8.
Turn on holding the roller and go to the trainer menu, click.
Then you may see that it is "inhibited" so select that and change to"Programmable Master".
Set THR, AIL, ELE, RUD to master
Set GER (ch5), AX1 (ch6) to slave
Activate the trainer switch
plug pan/tilt servos in ch5/ch6
Connect cable from headset to slave plug under the DX8.

Taranis-plus head tracking setup for JR port use , and also EZUHF JR module use.

Taranis-plus with open tx HT setup.

Here's how I have found it to work on my new Taranis -plus for the Fatshark HT .

For connecting to the JR port on back of radio.

First of all, make sure you have the radio set for MASTER in the model setup screen

Next is the Input setup screen 

Next is the Mixer setup screen

Thats it , done .
Plug in your JR cable to the goggles and Taranis and have working Headtracking 


Next is the extremely hard and notoriously difficult setup for the EZ-UHF JR Module .

Plug in the EZUHF JR Headtracking cable to the goggles and have it power the goggles too, and have it just work 
Having the settings for the JR port left in the radio makes no difference to the direct EZUHF connection as it bypasses it anyway.
