You can either utilize a cable that comes off the TBS

Crossfire module bay adapter or aquire the connector

seperately. In our example we used the iX12 Crossfire

adapter (SPMA3090) and attached a female servo lead to

the blue (TX) and Black (GND) leads.

Step 6) Update the DX9 Airware for Serial Port Access

You will now want to 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. You may need to reference the change log readme file for the update

download to find this information.

Once your DX9 is updated, you will find the Serial Port Setup menu in the system setup menu. Inside

that menu change the settings as shown and your radio is ready to utilize the TBS Crossfire via the CRSF

Protocol.
