Features:
Twooperationmodes: PPM mode and serial mode.
– When in PPM mode, there are 31 different protocols (protocol NO.0 is reservedfor serial mode) mapping to the 16-position protocol selection switch on the module. They are listed in the default protocols table below, when the green light is off, you can use the switch to choose protocol NO. 1 to NO.15, when the green light is on, you can choose protocol NO.16 to NO.31.
– To turn on/off the green light, Please follow these steps:
Turn off you transmitter, point the protocol switch to0, hold and press the bind button of RF module, then turnon your transmitter, after 3seconds, release the button.

Normal Use Operationin PPM Mode:
1.Install RF Module in position,Set PPM signal output on you transmitter.
2.According to the default protocolstable, turn the arrow sign(the side with a verticalslot) of protocol switchto the proper number to choose protocol.
3.After finish binding operation, Poweron yourtransmitter, the red light of RF module will beon, then RFmoduleis ready to work, after that poweron your receiver (or craft).
4.Protocol selection is done at the beginning of power up, so if you want to change protocol during operation, you should recycle the power.
5.The red light will blink slowly if there is no valid PPM signal.

Binding Operationin PPM Mode:
1.Power on your receiver, and set itto binding mode.
2.Hold and press the bind button of RF module, and then turnon your transmitter, after 3seconds, release the button, you will see the redlight flashing rapidly, then RF module is in binding mode, and the redlight will go solid after binding.
3.Some protocols (eg: S-FHSS)dont have binding procedure on RF module, and some protocols(eg: hubsan, e010)will autobindwhen power up.

Operationin Serial Mode:
When the green light is off, and the protocol switch is point to0, you can access serial mode.Transmitter that supports the er9X/erSky9X or Open TX firmware can work in this mode,The model protocol selection and binding is done from the Model Settings menu on the transmitter, For telemetry capable transmitters, the telemetry integration is done seamlessly with the transmitterfirmware.

Notice:
-The jumpers and header attached is used for updating firmware of TX module through USB serial cable. Please remove them for normal use..
-Sometimes, you may need a power recycle when you choose a new protocol. for example, protocol changes from Q303 to HISKY.
-For FRSKY and S-FHSS protocol, you may need set the value of Fine or Option (in the Model Settings menu) properly to bind with your model. The value is varied, since itspartly depended on your model.
