What’s New!

• Two auto-detected modulations of PXX (mode selection, bind, model match, range check, failsafe, etc. on radio side) or CPPM.
• Three selectable modes of D8 (existing 8ch two-way), D16 (new 16ch two-way full duplex transmission) and LR12 (new 12ch one-waylong range).
• Smart Port enabled, realizing two-way full duplex transmission.
• Detect the module antenna’s working status and give sound warnings if the module antenna is broken or does not have intactcontact, etc.
• Super lower latency (approx. 1/3 of current systems) and higher precision (transmitter’s hardware and software support required, such as FrSky transmitters).

Smart Port:

Smart Port (S. Port) is a signal wire full duplex digital transmission interface developed by FrSky Electronic Co., Ltd. All products enabled with Smart Port (including XHT module, X8R receiver, new hub-less sensors, new Smart Dashboard, etc), serial port user data and other user input/output devices can be connected without limitations for numbers or sequences at a high transmission speed.

Product Usage Instructions

Binding Procedure:

Binding is the process of uniquely associating a particular receiver to a transmitter module. A transmitter module can be bound to multiple receivers (not to be used simultaneously). A receiver can only be bound to one transmitter module. Follow the steps below to finish the binding procedure.

1. Turn on the transmitter module and receiver.
2. Put the transmitter module in binding mode (refer to your transmitter’s manual for instructions).
3. Press the bind button on the receiver.
4. The LED indication on both the transmitter module and receiver should change to indicate successful binding.
5. After completing the binding procedure, recycle the power and check if the receiver is really under control by the linked transmitter.

Range Check:

The FrSky telemetry system has a feature to return the Received Signal Strength Indication (RSSI) of the receiver to the transmitter. The transmitter develops an internal voltage representing the receiver signal strength. Alarms are programmed in the transmitter to warn the pilot when the model is nearing maximum control range. Refer to the table below for reference.

FAQ

• Q: What is Smart Port?
  A: Smart Port is a signal wire full duplex digital transmission interface developed by FrSky Electronic Co., Ltd. It allows for high-speed transmission of serial port user data and connection of other user input/output devices without limitations.

• Q: How many modes does the XHT module support?
  A: The XHT module supports three selectable modes: D8, D16, and LR12.

• Q: Can I bind multiple receivers to one XHT module?
  A: Yes, you can bind multiple receivers to one XHT module, but they cannot be used simultaneously.

• Q: Where can I find technical support for the product?
  A: For technical support, you can contact [email protected].

Binding Procedure

Binding is the process of uniquely associating a particular receiver to a transmitter module. A transmitter module can be bound to multiple receivers (not to be used simultaneously). A receiver can only be bound to one transmitter module. Follow the steps below to finish the binding procedure.

1. Turn on the transmitter while holding the F/S button on the XHT module (see Mode and Compatibility table above). Release the button. The RED LED on the XHT module will flash and GREEN LED ON , indicating the transmitter is ready to bind to the receiver.
2. Connect the battery to the receiver while holding the F/S button on the receiver. The RED LED on the receiver will flash, indicating the binding process is completed (please refer to the corresponding receiver’s instruction manual for details).
3. Turn off both the transmitter and the receiver.
4. Turn on the transmitter and connect the battery. The GREEN LED on the receiver indicates the receiver is receiving commands from the transmitter. The receiver/transmitter module binding will not have to be repeated, unless one of the two is replaced.

Note : After binding procedure is completed, recycle the power and check if the receiver is really under control by linked transmitter.

Range Check

A pre-flight range check should be done before each flying session. Reflections from nearby metal fences, concrete buildings or tress can cause loss of signal both during range check and during the flight.
Follow the steps below to perform the range check.

1. Place the model at least 60cm (two feet) above non-metal contaminated ground (e.g. on a wooden bench).
2. The receiver antennas should be separated in the model, and do not touch the ground.
3. The module antenna should be in a vertical position.
4. Turn on the transmitter and the receiver, press the F/S button on the XHT module for 4 seconds to enter range check mode, the RED LED will be off, GREEN LED will flash rapidly. The effective distance will be decreased to 1/30 of full range.
5. Walk away from the model while simultaneously operating the controls on the transmitter to confirm all controls’ normal operation.(please refer to the corresponding receiver’s instruction manual for details).
6. Press the F/S button on the XHT module for 1~2seconds to exit range check mode, RED LED will be back on, indicating normal operation is back.
