Reverse engineering the Mitsubishi AC Infrared protocol

This post is the second in a two-part series about Reverse Engineering AC Infrared protocols. This time we look at the Mitsubishi Air Conditioner IR Protocol. The project was undertaken by  two of our users in France (Vincent & Mathieu), with the help of AnalysIR, who  collaborated to reverse engineer this Mitsubishi and previously the Panasonic AC Infrared protocol, both examples of the more challenging AC Infrared protocols. Not only did they identify the individual field codes & checksum but also provided some impressive documentation. Detailed information is available via GitHub which is linked below. This 288 data bit Mitsubishi AC Infrared protocol is composed of two consecutive frames. Both frames are always identical for each signal sent. In common with most AC units the complete settings are sent with every IR signal (temperature, fan, swing etc…). AnalysIR was used to record and turn the signal into HEX/Binary format from which the reverse engineering of the individual fields was tackled.

Reverse engineering the Panasonic AC Infrared protocol

Recently, two of our users in France (Vincent & Mathieu) collaborated to reverse engineer the Panasonic AC Infrared protocol, one of the more challenging AC Infrared protocols using AnalysIR. Not only did they identify the codes & checksum but also provided some impressive documentation and full source code to help others. Detailed information is available via GitHub which is linked below. This 216 data bit Panasonic AC Infrared protocol is composed of two consecutive frames. The first frame remains constant for every command sent to the AC unit. In common with most AC units the complete configuration is sent with every IR signal (temperature, fan, swing etc…). AnalysIR was used to record and turn the signal into HEX/Binary format from which the reverse engineering of the individual fields was tackled.

Video: AnalysIR Demo Batch Infrared Decoding

Here we show a screen capture demonstration of the ‘Batch Decoding’ feature of AnalysIR. We show Infrared signals from 4 different Air Conditioners and how we can load them into AnalysIR and execute a batch decode of all of the signals in one easy step. Included are signals from Panasonic, Vestel, Fujitsu & Daikin

Latest ‘New Year’ release of AnalysIR with full support for USB IR Toy and more.

Dublin, Ireland – 31st January 2014. We are happy to announce the latest ‘New Year’ release of AnalysIR to all our backers & supporters. Since the completion of the crowd-funding campaign on Indiegogo we have added over 125 updates and enhancements to AnalysIR, with more to come.

A major highlight of this release is full AnalysIR support for USB IR Toy from Dangerous Prototypes (V1 & V2 hardware) for decoding and resending IR signals at all common modulation frequencies. In our opinion, AnalysIR is now the premier GUI supporting DP’s IR toy, not to mention the Arduino, RPi, MSP430 F5529 LaunchPad (beta)  and more. A selection of enhancements in this latest release, include: Continue reading Latest ‘New Year’ release of AnalysIR with full support for USB IR Toy and more.
