JUMPER JP4IN1 Multiprotocol Module

Brief Introduction:

The JP4IN1 integrates the CC2500, NRF24L01, A7105 and CYRF6936 RF chips into one PCB. The

JP4IN1 is an OpenTX original accessory which can do serial digital signal communication with the

Frsky series radios. Recognizing PPM signal from radio output, then converted to the

corresponding radio protocol to achieve control of the fixed wing and drone aircraft. Supported

protocols such as: Walkera DEVO, Spectrum DSM2/DSMX, Flysky, Esky, Frsky, WLtoys, Hubsan,

Hisky, Futaba SFHSS Assan etc are built in..

The JP4IN1 module offers greater flexibility with the ability to control most protocals and

popular brands in the market today. It also gives the user the ability to use a real RC radio for

more precise control and a better flying experience than the small radios often included with

ready to fly products.

Note: due to the copyright of the protocol, JP4IN1 only provides hardware, please refer

Once X9D finished upgrade: power off radio, insert JP4IN1 module, then power on again. (Note: please make sure JP4IN1 antenna is assembled before powering on radio). As shown in below Fig: Enter the “MOEL SET UP” menu, close Internal RF and open External RF, the red and green led both are on. Select the protocols and sub protocols you need for bind in External RF menu, and then "bind".

Turn on or turn off the green light procedures are as following： Turn off radio, rotate the encoder knob switch to "0" position, then press and hold the black bind button, power on the radio meanwhile, release the button after 3 seconds, the green light will flash, optional protocols switch simultaneously. Normal use and operation in PPM mode: 1. Fix JP4IN1 with antenna on the radio, open PPM signal output of radio. 2. Turn the encoder knob (The current position i.e.
