User Manual

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. There are two pages, 10/13 and 11/13 where pre-formatted and
customisable screens for information can be found.
For a detailed explanation of the various sensors and all other things related to FrSky telemetry,
please refer to the FrSky Telemetry Wiki:

Real Time Clock Battery
The 9XR Pro keeps track of time and date by means of a real time clock (RTC) that runs even
when the transmitter is turned off. The clock is powered by a lithium cell (installed in a holder on
the main circuit board), which is expected to have a life of many years. Should it ever require
replacement, use a CR2032 cell or equivalent. Time and date can be reset in the Radio Settings
pages.
Other Possibilities
Other capabilities of the 9XR Pro hardware when driven by the Ersky9X firmware include:
24 Channels
Older modules such as the FrSky DJT can typically transmit 8 channels, the XJT 16 channels,
while later modules will support as many as 24 channels with a compatible receiver. This includes
an S-Bus stream that can be used, for example, by helicopter and multirotor flight controllers or
compatible servos.
Voice Announcements and Alarms
Any transmitter event can be announced and any alarm or telemetry value spoken (see the manual
Using Voice with Ersky9x). This can help the pilot keep track of current switch settings and take in
information about time or telemetry data.
The 9XR Pro speaker is located on the front of the radio. Its volume can be set in the Radio Set-up
pages or control can be assigned to one of the potentiometers. A headphone jack is located under
the rubber flap on the bottom of the transmitter. When headphones are used the speaker is silent.
Haptic Feedback
Some alarms and events can be signalled by haptic feedback, meaning that the transmitter
vibrates in the pilot's hands. The strength of vibration can be changed in the radio set-up pages.
Telemetry Data Logging
Data from your model may be stored on the SD card. The data files so produced have the name of
the model, date and time in the header. They are in comma delimited (.csv) files suitable for
loading into a spreadsheet. The data can be analysed, graphed and exported to a word processor.
