Spektrum Instructional Series - How To Upgrade your DX9 for TBS Crossfire Using CRSF Protocol

The moment you have all been waiting for is upon us! You can now make one of the best RC radios on the market CRSF compatible! This is a very easy mod that you can do, all you need is a servo lead and a fine point soldering iron.

Once you have completed the modification, Proceed to Spektrumrc.com to download the firmware required to turn on this serial data port. Once logged in, find your registered DX9 (if you have not done so, do so now) and then find Update Firmware. Browse through until you locate the latest firmware that incorporates Crossfire/Serial data port. Please reference the change log readme file for the update download to find this information. Once the DX9 is updated, the Serial Port Setup menu will be located in the system setup menu. Inside that menu change the settings as shown and the radio is ready to utilize the TBS Crossfire via the CRSF Protocol.

The TBS Crossfire long range system is intended to provide less latency and greater range than standard systems in the DX9 radio. However, installing the Crossfire system requires soldering a new serial port onto the transmitter circuit board. We have provided a comprehensive tutorial to perform this modification on a Spektrum DX9 Transmitter correctly. Please be aware that any self-modification of the transmitter will void your transmitter warranty. Future service on a self-modified transmitter will not be denied, but any future service performed will not be covered under warranty. As a result, Horizon strongly recommends sending your Spektrum radio in for service and allowing our professional service technicians to perform the Crossfire system installation and preserve your warranty. Please include a note in the service request asking for this modification.
Once we receive your Transmitter, an authorized Spektrum Service Technician will perform the modification and confirm that the Transmitter functions properly post upgrade. Once the modification is
completed, your radio will have a common servo connector leading out the back of the radio that offers serial port signal and ground. Use this plug to connect and communicate with your serial input module.
The cost for this modification is $75 plus shipping and is currently only offered for the Spektrum DX9 andDX9 Black Edition transmitters.
