JUMPER JP4IN1 Multiprotocol Module

Brief Introduction:

The JP4IN1 integrates the CC2500,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
following link to download the firmware:

How to install firmware with USB port? Need some clear and simple instructions.
Instructions at the link above are very complicated and needs USBAVR etc.

  • Page 2 Two working modes: Serial Port mode & PPM mode. 1. Normal operation in Serial Port mode (Bi-directional digital signal communication between radio and JP4IN1.) Rotate the encoder knob to"0" to enter the serial port mode, all existing protocols can be used...
  • Page 3 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.
