The Mode Control Panel (hereafter called the MCP) is central to the operation of all sophisticated aircraft. The most commonly available hardware version is the 737MCP from various manufacturers at various prices. As I am an advocate of Opencockpits hardware I decided to purchase their version. It helped that their's was also the cheapest! When it arrived I was a little apprehensive as to the difficulty in getting it operational in the simulator, but as it turned out I needn't have worried. It was simply a case of plugging it into a USB port, loading the cofig file in SIOC, and starting Flight Sim. Below are some pics of the beast in action.
This plug & play device is fully built and ready to plug into an available powered hub.
Download the SIOC file to run this unit.
The only drawback with this hardware is that it doesn't come with backlighting and it's going to be a tight fit retrofitting backlighting between these circuit boards, but not impossible. Download my complete tutorial on backlighting the MCP.
The grey cable is the USB lead but there's also a separate 5v power cable which is recommended if you intend to run the device direct from your computers USB outputs. If you run if off a powered hub you don't need to connect this.
All bolted in and running in the sim. Here you can see the default 737-800 loaded for testing purposes however it works equally well with the Flight1 PC12.
To configure the device, simply load the text file "IOCards_FS2004.txt" into SIOC and compile it as an .ssi file. Edit the SIOC.ini file to load the above file and voila! Whenever you run SIOC.exe this file will run with all the required parameters to run the MCP in any aircraft you like.
Of course if you already have a .ssi file with all your other OC hardware parameters then you'll have to incorporate the functions in the above text file in order for them to run together.
The operation of the encoders is a joy to behold! They are so smooth and accurate. It's definitely a worthwhile purchase no matter what aircraft you fly.
