FrSky is constantly looking to improve performance and reliability of RC transmission. The FrSky ACCESS protocol is the most advanced to date as it offers more features than traditional protocols.

FrSky has developed excellent new ideas that expand the role that a traditional protocol would play. Building on our well acclaimed ACCST protocol, ACCESS offers visionary features like Smart Share™, Smart Match™, and Trio Control ™. Once a receiver is bound to a radio, it can be re-bound at any time without accessing your receivers bind button. Sharing models has never been easier, and updating has also been simplified, you no longer need to physically connect your receivers for updating. In addition, new tools like a Spectrum Analyzer and Power Meter are now available on your transmitter.

Always on the cutting edge of technology, we have developed ACCESS to improve your flying experience and allow you to do more with your transmitter and receiver than ever before.

Main Functions and Features

Elevated performance with faster baud rate and lower latency

  • Supports 24 full-range channels
    Some models require more than the 16 provided by the previous protocol. For these users, ACCESS can use up to 24 channels from one signal.
  • Increased baud rate and lower latency
    ACCESS offers faster speeds and more precision tricks than ever before. It’s extremely important to stay ahead of the competition. Less latency translates to quicker response time.

More convenient M2M (Multi to Multi) technology

  • Wireless binding, updates, and configuration
    The need to access the receiver for binding, updates, and configuration are eliminated because this procedure is now achieved wirelessly. Thanks to wireless binding it has never been easier to share your models with other FrSky users.  (Smart ShareTM).
  • Automatic binding (Smart MatchTM)
    Binding to your model is more secure than ever before. You can easily bind to your models wirelessly without accessing your receiver. And dual certification of the transmitter and receiver make the binding process safer than before.
  • Channel remapping
    Have you ever plugged-in and installed a receiver just to find out everything was plugged into the wrong input? Now you can simply remap the channel order on your transmitter.
  • Manageable telemetry (Trio ControlTM)
    You are able to configure telemetry for up to 3 receivers simultaneously through the radio. You no longer need to use STK tools and Smart Port allows the use of third-party input/output devices with pass-through mode.

More reliability and safety – Anti-interference and Anti-hijack system

  • Allows radio to act as a Spectrum Analyzer
    You are now able to use your transmitter to survey the airwaves, which can measure your signal strength and others in your area. The Spectrum Analyzer allows the user to measure the power, noise, and distortion of the frequencies around.
  • Allows radio to act as a Power Meter
    The RF power of external devices can be measured with the addition of this new feature.
  • Advanced Encryption Algorithm
    Higher Encryption means more peace of mind that your model’s signal will not be interfered with.

Q&A

Q: What is Smart MatchTM ?
A: Now you get extra security before you fly. Smart MatchTM acquires dual certification from your receiver and your transmitter to give you double the protection.

 

Q: What is Smart ShareTM?
A: Now you can bind multiple transmitters to a receiver and Smart ShareTM assures that you have a unique certification for each transmitter. If you fly competitively you can set up two identical transmitters and have a spare one ready to go in the event you need it. No need to find the bind button on the receiver. It’s all ready to go. Many clubs have trainer aircraft to help new modelers. Now it is easy to allow authorized multiple transmitters to bind with the trainer aircraft receiver.

 

Q: What is Trio ControlTM?
A: ACCESS allows one transmitter to control the signal and/or telemetry for up to 3 receivers per model. Receiver redundancy provides an extra layer of safety when flying larger models.

 

Q: Can I update previous FrSky products to the ACCESS protocol firmware?
A: All previous and present FrSky transmitters can be updated to the ACCESS protocol, The X, XM, RX, GX and S series receiver support will be gradually added to the supported list.

 

Q: What are the improvements of ACCESS protocol when compare to ACCST?
A: The ACCESS protocol supports up to 24 channels with increased transmission rate and lower latency (Total latency from Tx stick input to Rx channel output) and the elevated performance.
  • 8 channel mode: Fixed 11ms latency / Telemetry upstream rate increased 40% / Telemetry downstream rate increased 60%
  • 16 channel mode: 14 ~ 23ms latency / Telemetry upstream rate increased 40% / Telemetry downstream rate increased 60%
  • 24 channel mode: 14 ~ 23ms latency / Telemetry downstream rate increased by 60%

 

Q: Is there any differences between the old and new products when using the ACCESS protocol?
A: Yes. Some of the new functions like the Power Meter were developed and optimized with the new FrSky transmitters (e.g. Taranis X-Lite Pro). When it comes to wireless performance, the new upgraded RF module is built specifically to use the new ACCESS protocol. This will provide a superior link than if used on a standard module.

 

Q: What frequency band will be supported by the new ACCESS protocol?
A: The FrSky ACCESS protocol will be applied to both 900MHz and 2.4GHz working frequency band, but exits the performance differences. And FrSky will release our dual frequency products like the radios, Tx modules and receivers this year.

 

Q: In what scenario can I use the Smart ShareTM function?
  1. A user has 3 different FrSky radios for each type of aircraft and would like to fly them all with a single radio. As long as the user has already bound to the receivers, they do not need to access the bind button on the receiver to switch transmitters.
  2. RC Competitors often carry a back-up radio just in case something happens to the primary radio. In this case, the pilot can switch to the 2nd radio without accessing the bind button on the receiver of their model.
  3. Clubs that own and operate community special purpose planes, like aircraft for towing gliders up to altitude, will no longer need to only have 1 designated radio for that plane. Each authorized pilot will be able to use his or her own FrSky Transmitter with their own unique identification ID.
  4. A user that wants to share a model with a friend can now allow the user to bind to the model without access to the bind button. When the model is returned, it can simply be re-bound without accessing the bind button.
