TBS Crossfire Manual
General functions
Binding
Binding a receiver to your Crossfire is an easy task and does not require 3 hands or any special jumpering.
General note/ model match
You will notice that you can control any r/c model, even if you changed the model in your radio*. This is
caused by the fact that the Crossfire does not monitor the radio model. This means you have to make sure
that you selected the right model in your radio before you power up the receiver.
If you are used to FrSky, it’s the same behavior as when you set your receiver number to 00 in the mode
settings (with FrSky receivers)
*Model matching with the Crossfire and OpenTX is available since OpenTx 2.3.10
When do i need to bind again
There are a few cases when you need to rebind your transmitter to the receiver:
● You changed the region/ frequency setting*
● You updated your transmitter firmware
● You enabled multi-bind*
● You did a factory-reset on the receiver
● YOu changed you model id/ receiver number in Opentx*
* you can avoid a rebind, if you change these settings while the receiver is bound and powered up.
Binding issue - Double green flashing
If you get a double green flashing pattern on the receiver for several seconds after updating or binding,
you got an authentication error. To solve this issue:
● Shut down the receiver
● Set the Tx in bind mode
● Power up the receiver
● Push the
Bind
button on the Rx
After the binding the pattern may return but should be gone after a few seconds.
Binding issue - OpenTx 2.3.10
When you update your radio to OpenTx 2.3.10 you might find all your receivers are now unbound. If this is
the case, check the model match number. Due to the way OpenTx handels this feature, it might have set
up a model number. In this case just change it back to 00 and your receiver should be bound again.
