🧠🎹 MIDI DIN-5 • MDIN-6 (PS/2) Adapter

This adapter links devices using the classic 5-pin DIN connector—common in MIDI and AT keyboards—to systems with 6-pin mini-DIN (PS/2) ports. While not electrically universal, it’s used in specific legacy setups where pinouts align, especially in keyboard conversions and experimental control rigs.
 
🔧 Adapter Varieties
1️⃣ DIN-5 Male → MDIN-6 Female
Use Case: Connect AT-style keyboard to PS/2 port
Example: Vintage DIN-5 keyboard → modern PC with PS/2 input
Note: Most common configuration for keyboard compatibility
2️⃣ DIN-5 Female → MDIN-6 Male
Use Case: Connect PS/2-style keyboard or mouse to DIN-5 port
Example: PS/2 keyboard → legacy KVM switch or MIDI-style controller
Note: Less common; used in niche control setups or reverse patching
 
🖥️ Compatible Devices
⌨️ AT-style mechanical keyboards
🖱️ PS/2 keyboards and mice
🎹 MIDI controllers and synthesizers (DIN-5 side only)
🧠 Legacy KVM switches and control panels
🧪 Experimental rigs and signal converters
🧱 Embedded systems with custom I/O
 
✅ Common Uses
🔄 Convert AT keyboard to PS/2-compatible system
🧩 Patch PS/2 input devices into DIN-style control interfaces
🛠️ Extend life of vintage input hardware
🎛️ Prototype MIDI-to-PS/2 control bridges
🧪 Test legacy pinouts and signal compatibility
 
🧠 Signal Format Notes
DIN-5: 5-pin circular connector used in MIDI and AT keyboards
MDIN-6 (PS/2): 6-pin mini-DIN used in PS/2 keyboards and mice
Signal Type: Low-voltage serial data; not interchangeable without matching protocol
Pinout Sensitivity: Electrical compatibility varies—adapter only works if signal formats match
❗ MIDI and PS/2 are not directly compatible—adapter is for physical connection only
 
⚠️ Things to Watch Out For
🔌 Adapter does not convert signal—only physical interface
📏 Confirm pinout compatibility before use
🧯 Not suitable for MIDI-to-PS/2 conversion without active electronics
🔄 Some AT keyboards may not work with PS/2 ports even with adapter
🧪 Always test with known-good device before permanent install
 
🛠️ Quick Tips for Beginners
🔍 Identify connector types visually—DIN-5 is larger, MDIN-6 is smaller
🧭 Use DIN-5 Male → MDIN-6 Female for AT keyboard to PS/2 PC
🧰 Keep both adapter types in your legacy toolkit
🧪 Label adapters clearly—reversed gender can cause confusion
🧼 Store with protective caps to avoid bent pins
