Tr8B 是一款采用 AFHDS 3( 第三代自动跳频数字系统)

协议支持 8 个 PWM 通道信号输出的微型接收机。它具有

扣式双天线,支持双向传输,可实现回传功能,支持 2 个

Newport 接口(Newport 接口可自定义输入或输出的信号

类型:i-BUS2/S.BUS/i-BUS/PPM 等)。设计上也独辟蹊径,

在满足轻小常规应用的基础上提供了 DIY 配件,以满足不

同的需求。

The Tr8B receiver based on AFHDS 3 protocol( third-generation automatic 

frequency hopping digital system)is  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 adapts 

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 配件介绍

BVD 检测线

:当需要使用 BVD 功能检测电压时,先将 BVD 线的焊接头端(左图 [15] 位置 ) 焊接到

接收机的 BVD 焊点处(左图 [9] 位置) , 即可使用 BVD 功能检测电压。
注:

1.  使用 BVD 功能时,需要将检测的电池负极与接收机电源地(左图 [14] 位置)相连;

2.  BVD 电压检测范围: 0~70V 。

两组通道接口插针(对应通道 5、6、7 和 8)

:当需要使用 4 个以上通道或 Newport 时,将相应的

插针焊接到接收机预留的通道位置处即可。

请注意焊接完毕后,用新的热缩套管套住电路板,以防止使用过程中接触金属而造成短路!

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 pins 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 from contacting with metal, so as to avoid a short circuit !
