The new Frsky ACCESS system bind procedure is slightly different and confusing for new comers. In this post I will explain the steps on how to register and bind receivers to your ACCESS transmitter.
With the older ACCST protocol, binding is just binding. But with ACCESS, you now have to first register the receiver before binding.

1. Enabling ACCESS Mode
First thing first, ensure your radio is set to ACCESS mode.
Enter “Model Setup” on the radio, scroll down to “Internal RF”, in “Mode”, select “ACCESS”
2. Setting Channel Range
Next decide how many channels you want to use.
ACCESS supports up to 24 channels, but lower number of channel has less latency. For flying mini quads, generally 8 channels are more than enough and gives you the least latency.
3. Setting Receiver Number
Just leave it at 01 unless you know what you are doing.
You don’t normally have to worry about this. When you create a new model, the system will assign a receiver number automatically, but it can be changed easily too.
Receiver number is from 00 to 63, but 00 is not recommended by Frsky for some reason, so the default is 01 (lowest you should use).
Once the receiver is bound to the Taranis, bind procedure will not need to be repeated again unless the receiver number is changed. In this case, you can either set the receiver number back to the original one, or bind the receiver again.
4. Registering Receiver
Next to “Module”, select “Register”.
Now hold down the F/S button (bind button) on your receiver, then power it on.
Your receiver name should appear in “RX Name” on the screen.
Press the “Enter” key on the radio to complete the registration process, followed by a message “Registration OK”. You can now power down the receiver.
You can change UID, but only change it when you are using multiple receivers. Normally you can just leave it at default.
Note that once you’ve registered a receiver, you don’t normally have to do it ever again even after updating its firmware unless you want it to work with a different radio. This is one of the cool features of the ACCESS protocol.
If you have problem registering receiver, make sure both your receiver and internal RF module have the latest firmware. Here are the tutorials:
Next to “Receiver 1”, select “Bind”.
Now power your receiver, the name should appear on the screen. Select this receiver to complete the process and the system will confirm with message “Bind successful”. You do no need to press the “F/S” button to bind in ACCESS mode.
Frsky calls it “Automatic Binding” as you do not need to touch the receiver during binding as long as the receiver is previously registered.
6. Setting Failsafe
There are four failsafe options. For mini quad we recommend setting it to “No Pulse”.
- No pulse – receiver produces no pulses on all channels on loss of signal
- Hold – receiver continue to output the last positions before signal was lost
- Custom – preset to required positions on lost signal
- Receiver – set the failsafe on the receiver (follow receiver instructions)
Upon selecting a new failsafe option, please wait at least 9 seconds for failsafe to take effect.
7. Receiver Options
Not necessary to change anything, but I will cover these options in the future…
