Receiver

Introduction

The Tr8B receiver based on AFHDS 3 protocol( third-generation automatic frequency hopping digital system)is a micro receiver with 8 PWM channels. It features two button antennas, bidirectional data transmission, and data returning. It supports 2 Newport function interfaces( Newport interface can be customized with the input or output signal type: i-BUS2/S.BUS/i-BUS/PPM, etc.). The receiver adopts all transmitters and RF modules with AFHDS 3 protocol. The design is also unique. We provide DIY accessories to meet special demands, in addition to meeting conventional applications.

DIY accessories：
BVD cable: When you need to use the BVD function to detect voltage, first weld the BVD cable welding joint end (in the left figure [15] ) to the receiver’s BVD welding point in the left figure [9] ). Then you can use the BVD function to detect voltage.
Notes:

1. When using the BVD function, connect the negative terminal of the detected battery to the receiver’s power cathode (in the left figure [14]) .
2. BVD voltage detection range: 0 – 70 V.
   Two sets of channel interface pins (corresponding to channels 5, 6, 7, and 8): When more than 4 channels or Newports need to be used, just weld the corresponding ins to the channel position reserved in the receiver.
   It should be noted that you use a new heat-shrinkable sleeve to cover the circuit board to prevent contact with metal, so as to avoid a short circuit！

Binding

The receiver automatically enters the bound state upon power-on. That is, the receiver waits for 1 second after power-on, it enters the binding state if no connection is established with the transmitter. If the receiver enters the binding state and fails to bind with the transmitter within 10 seconds, it exits the bound state. If the receiver has succeeded in binding with the transmitter earlier (established a connection), it will continue to wait for a connection with the transmitter after the exit of the bound state.

• When this receiver and the transmitter complete the binding, please turn on the transmitter and then the receiver. If you turn on the receiver first, there may be a wrong binding at this time when there is a similar transmitter in the bound state. Please bear this in mind. The receiver supports two-way binding and one-way binding

The transmitter will display the information returned from the receiver after the two-way binding is completed. The receiver automatically enters the binding state once it is powered on, set to Two way or not at the transmitter side first before starting binding.
Follow the steps below to bind in two-way binding:

1. On the transmitter side, set Two way in the Bind setting menu, then put the transmitter into bind mode.
2. After the receiver is powered on, it will automatically enter the binding mode if it is not connected to the transmitter in 1 second.
3. When the LED of the receiver is solid on, the binding process should be completed. The transmitter exits the binding mode automatically.
4. Check to make sure the transmitter and receiver functions are working correctly, and repeat steps 1 to 3 (binding process) if any problems arise.

Follow the steps below to bind in one-way binding

1. On the transmitter side, set One way in the Bind setting menu, then put the transmitter into bind mode.
2. Put the receiver into bind mode (Refer to the description for Two way binding above ).
3. When the LED of the receiver is in a slow flashing state, the binding process should be completed. You need to manually put the transmitter to exit the binding mode. Then  The LED of the receiver is solid on, indicating that the binding is completed.
4. Check to make sure the transmitter and receiver functions are working correctly, and repeat steps 1 to 3 (binding process) if any problems arise.
   Note: Put the transmitter into bind mode first, then put the receiver into bind mode. If the binding is not completed within ten seconds, the LED of the receiver will enter its slow flashing state.

 Firmware update

The firmware of this receiver is updated through the FlyskyAssistant (Only version 3.0 or above is supported. The firmware of FlyskyAssistant is available on the Flysky official website).
This receiver can be updated in the following two ways:

1. After the binding between the transmitter and the receiver (the LED of the receiver is solid on), connect the transmitter to the computer, then open the FlyskyAssistant on the computer to update the firmware.
2. Connect the transmitter to the computer. Then put the receiver to enter the forced update mode by referring to the following way (The LED of the receiver operates in a three-flash-one-off manner repeatedly). Afterward, open the FlyskyAssistant on the computer to update the firmware.
   • Connect the signal pin of the CH3 to the signal pin of the CH4 first, then power on the receiver

Failsafe

The failsafe function is used to output the channel value according to the out-of-control protection value set by the user after the receiver loses its signal and is out of control to protect the model and personnel. It can also be set failsafe for each channel respectively. This receiver supports three failsafe modes: No output, Hold, and Fixed value.
No output It is in a suspended state for the interface of PWM; Hold Keep the last output value; Fixed value Output the failsafe values set for each channel.
Notes:

1. For bus signal types such as PPM/i-BUS/S.BUS/i-BUS2, a single or several of these channels are not allowed to be in No output mode. The actual signal is held at the last output value when the channel is set to No output mode.
2. Because the S.BUS/i-BUS2 signal information contains failsafe flag bits, the failsafe settings of each channel are communicated to subsequent devices by the failsafe flag bits. If the connected devices support the failsafe flag bit analysis, the failsafe values set for each channel are output after being out of control.
3. For the signal PPM/i-BUS without failsafe flag bits, it supports the setting of the signal to No output mode in case of out of control. After setting to No output mode, regardless of the setting of the failsafe of each channel, each channel will be in No output mode after being out of control.

Attentions:

• Make sure the product is installed and calibrated correctly, failure to do so may result in serious injury.
• Make sure the receiver’s battery is disconnected before turning off the transmitter, failure to do so can result out of control. The unreasonable setting of the Failsafe may cause accidents.
• Make sure the receiver is mounted away from motors, electronic speed controllers, or any device that emits excessive electrical noise.
• Keep the receiver’s antenna at least 1cm away from conductive materials such as carbon or metal.
• Do not power on the receiver during the setup process to prevent loss of control.
