9XR Pro: Introduction to the Hardware

A guide to using the Turnigy 9XR Pro Transmitter

Welcome to the Turnigy 9XR Pro and Ersky9x system. We'd like to point out a few things on this

radio which are different to other radios and then how to learn more about it and its tremendous

capabilities.

Here's what's in this manual:

Which Module?

The 9XR Pro accepts almost any make of transmitter module of the JR shape. If you already have

a JR format module and a number of receivers, they will operate perfectly well with the 9XR Pro.

Some modules need a little tape to make them a snug fit. Others need to be inserted carefully to

avoid bending the pins.

The receivers you use must match the module. To bind the receiver to the transmitter follow the

manufacturer's instructions.

You have two main choices of module at this time:

1. FrSky, either DJT or XJT. The DJT supports the older V8 series receivers plus D-series

(telemetry) receivers. The XJT supports D-series and V8-II receivers, plus the newer

X series receivers.

2. DSM2/DSMX: The OrangeRX module supports both protocols.

In addition, a module using the DSM protocol and providing telemetry is expected soon.

The remarkable capabilities of Ersky9x firmware, including powerful mixing, large model memory,

flexible radio setup, voice announcements, haptic feedback, communication with your computer

and Eepskye will be available no matter what brand of module you use.

Battery Selection

The 9XR radios require an input voltage between 6 and 13 volts, allowing use of many different

batteries. The main options are outlined below.

The 9XR battery connector is compatible only with a JST plug of the type used for the balance lead

on a 3s LiPo/LiFe battery. This means that such a battery can safely be plugged directly into the

9XR. Other types of battery may require fitting a JST-XH 4 pin plug. Only the outer two wires are

used: in the transmitter socket the left pin is negative (black) and the right one is positive (red). Be extremely careful about polarity. Check the polarity of any battery before plugging in. The minimum practical battery capacity is about 800 mAh (milliampere-hour) but batteries in the 1500-2500 mAh range are normally used. These should give at least 10 hours of operation. The Turnigy 9XR Safety Protected 11.1v (3s) 2200mAh 1.
PAGE 3
LiFe (Lithium-Iron) A very inexpensive 3s 1500 mAh LiFe battery specifically for transmitters is available. LiFe batteries are safer than LiPo but still need proper handling. For example, if allowed to discharge fully (by leaving the transmitter turned on) they will be damaged and not be rechargeable in the normal way. Instructions for recovery can be found online but seldom work more than once with a given battery. The typical maximum charge voltage is 10.8 volts, but the battery settles back to 9.

At the bottom of the page opposite A8 is the transmitter voltage reading. Use the DOWN key to scroll to it. Press MENU to allow changes. The LEFT and RIGHT keys will adjust the voltage to agree with the voltmeter. Press MENU again when finished and EXIT to leave the item. Now set the Battery Warning on page 1/11: Use UP to go to the top of the page and then LEFT to go to page 1/11. Select Battery Warning. Use the LEFT and RIGHT keys to set the voltage to suit your battery, as recommended above.
PAGE 5
Select a number in mAh that is no more than 80% of the battery capacity. When the battery capacity used reaches this value an alert message will be announced. If the field is left at 0 no alarm will be announced. You have to remember to reset the battery capacity after recharging the battery. Connections Under the rubber flap on the bottom right corner are a number of connections. At the bottom is the Audio headphone connection for an 8 to 32 ohm headset. Next up is the SD card slot.

your computer as a mass storage device and can be opened just like a disk drive. The card can be any size but 2 GB will be large enough for most purposes. Contents of the Card There are normally at least four folders in the root directory of the card: Voice, Firmware, Logs and Manuals. The Voice folder contains .wav sound files used for voice announcements by the system.
PAGE 7
Trainer Port Connections On the top rear side of the radio are trainer cable connection ports for both JR and Futaba cables. The Futaba port is also used for connecting the FrSky telemetry cable from the FrSky DJT module. This cable is not supplied with the radio or module and must be purchased separately. Front View Telemetry Basics Telemetry means that values read by sensors in the aircraft can be sent by the receiver back to the transmitter.
PAGE 8
The cable (top) has a second lead to allow a trainer cord to be connected at the same time as the telemetry cable. This may be removed if you don't want it. The photo above above shows a DIY installation. The DJT module, or an XJT module in D8 mode, when used with a D-series receiver will output all hub sensor data via the serial port. The display of the received data and its format is determined by what you specify in the telemetry screens in the Model Setup pages.

Appendix A: Modifying a FrSky DJT Module for Telemetry For telemetry data from the model to be conveyed from the module to the 9XR Pro transmitter for display and sounding of warnings, additional connections are required. These can be provided by a cable from the Futaba port on the transmitter to the socket on the DJT module. Alternatively, the module can be modified to eliminate the need for a cable. Doing so will void your manufacturers warranty.

The switches and LED assembly are mounted on the this board too, so that when you remove the board they will be removed with it. Hold the box lengthwise with both hands, your thumbs on the top edges and fingers pressing underneath the base of the box. Push upwards with your fingers, bending the base of the box upwards and hence pushing the circuit board up. With enough force the circuit board will spring out of the detents at one end. Remove the box.
PAGE 12
Assembly of the Module One end of the circuit board has the corners removed to fit the pillars in the box for the back cover screws. Place the circuit board inside the box and carefully push it to the bottom so that it rests parallel with the bottom of the box. Be careful not to apply force to the antenna cable and clip. Using a thumb at each end push the circuit board until it engages the detents. At the end adjacent to the switches, the cover has tags which slot into the module box.
