DCS-BIOS is an Export.lua script for use with DCS: World, enabling external hardware and software to interact with the clickable cockpit of a DCS aircraft.
Note
DCS-Skunkworks DCS-BIOS is a continuation of the original DCS-BIOS, which is no longer updated.
Getting started with DCS-BIOS is easy! Just follow these simple steps.
Start by finding your DCS Saved Games folder. On Windows, this is likely either:
C:\Users\USERNAME\Saved Games\DCSC:\Users\USERNAME\Saved Games\DCS.openbeta
Within that folder, you find the folder called Scripts. Create one if it does not exist. The final path should look like:
C:\Users\USERNAME\Saved Games\DCS\ScriptsC:\Users\USERNAME\Saved Games\DCS.openbeta\Scripts
Note
The process for updating DCS-BIOS is exactly the same as installing it.
- Go to the latest release
- Download
DCS-BIOS_x.y.z.zip - Extract the zip file
- Within the extracted folder, copy the
DCS-BIOSfolder into the previously mentioned scripts folder. - If your Scripts folder does not have an
Export.luafile, copy theExport.luafile over - If your scripts folder does have an
Export.luafile, add the following line to the enddofile(lfs.writedir() .. [[Scripts\DCS-BIOS\BIOS.lua]])

Arduino Users should download the Source code (zip) on the Release page to get all needed files.
You don't need to be a programmer or electrical engineer to build your own panels. The DCS-BIOS User Guide includes step-by-step instructions on how to connect your panel to DCS using DCS-BIOS and the beginner-friendly Arduino microcontroller platform. You don't have to write any code yourself.
Both socat and DCSBIOSBridge can be used to connect to your device.
Important
If using socat, the files in the .zip file must be unzipped directly in the socat folder. The path must be /socat/socat.exe
If you are working a lot with hardware, it may come in handy to log and replay dcs-bios data. There are two scripts in Programs/tools that allow you to do so.
python connect-logger.py will log all dcs-bios data to dcsbios_data.json. Ensure that you start the logger before loading a mission in order to capture the mission-start message properly.
python replay-log.py will ask for a serial port like connect-serial-port.cmd and replay the data to that com-port. When it reaches the end of the file, it will loop forever until you close it. The first message will not be repeated as this is usualy the mission-start message and should only be sent once.
dcsbios_data.json This file contains the logged data in hex format. If you are familiar with the format of dcs-bios messages, you may modify the file by hand if needed. The included sample file is a recording of the A-10C with a blinking Master Caution light.
The Developer Guide explains how to connect to and interpret the DCS-BIOS export data stream and how to send commands to DCS-BIOS in order to operate controls inside the cockpit.
There are also a variety of client libraries available, including (but not limited to):
| Language | Library |
|---|---|
| C# | DCS-BIOS Communicator |
Note
Aircraft with multiple variants (e.g. A-10C/A-10C II, F-14A/B, etc.) are considered single modules.

DCS-BIOS supports many community mods out-of-the-box.
In order to a Flaming-Cliffs-based mod which is not supported by DCS-BIOS, add the following to the bottom of DCS-BIOS/lib/AircraftList.lua:
add("PlaneName", false)Tip
To get the correct plane name, open the DCS-BIOS Reference Tool (MetadataStart) while you fly that plane and look what value _ACFT_NAME has.
