Binding
Make sure you have updated the firmware to at least version 2.87! Binding is super simple.
1. Power up the TBS CROSSFIRE transmitter
2. On the standard transmitter, enter the configuration menu by pressing and holding the joystick for
3 seconds, select “General” and “Binding” - a message “Binding” will start blinking, waiting for the
receiver. On the micro transmitter, a short press on the button will initiate binding mode.
3. Power up the receiver (without pressing the Bind button!), if your receiver has not been previously
bound, it will automatically bind. Otherwise, press and release the “BIND” button on the receiver
to initiate binding. You need to push the button within one minute to avoid the timeout. If the
status LED starts flashing slowly the receiver has switched successfully to bind mode.
4. Within a few seconds the process will finish with a “Binding complete” message on the standard
transmitter, or a solid green LED on the micro transmitter. If it doesn’t bind, please verify that your
firmware is to the newest version on both the receiver and the transmitter. You may want to bind
through LUA script on the Micro TX to walk through the wizard on the firmware update.
BST connectivity
The TBS CROSSFIRE Diversity Nano RX comes with a fully featured BST port. To connect it to other devices
like TBS CORE PRO, FPVision layer, GPS or other TBS peripherals, a custom cable needs to be made. BST
connector usually have 5 pins, but on the CROSSFIRE Nano RX only SDA, SCL and GND has to be connected.
Best practise is to use a BST cable, cut the connector on one and and cut the unused wires on the other
connector. Then solder the required wires accordingly.
