Adaptér InLine AT 9pin Sub-D samec / 25pin Sub-D samec krátký, InLine, 31219L

Short 25-pin Sub-D male to 9-pin Sub-D male adapter with a fixed pin assignment (9→25): 1→8, 2→3, 3→2, 4→20, 5→7, 6→6, 7→4, 8→5, 9→22; grounds tied GND→GND. The compact InLine AT Adapter (model 31219L) provides a space-saving solution for connecting equipment with 9-pin and 25-pin D-sub interfaces. It has a silver finish and a durable build suitable for a variety of environments.

Advantages

The adapter offers a short form factor that reduces cable clutter and simplifies connections between devices with differing Sub-D pinouts. Fixed pin mapping is clearly defined to ensure predictable signal routing. Durable construction and a standard 9-pin and 25-pin Sub-D male configuration make the adapter compatible with many legacy and industrial devices.

Suitable for

• Connecting a 9-pin D-sub serial port to a 25-pin D-sub connector when the specified pin mapping is required
• Legacy computer and industrial equipment with male Sub-D interfaces
• Compact installations where a short adapter is preferred

How to use

Align the 9-pin male connector with the corresponding 9-pin female port and the 25-pin male connector with the corresponding 25-pin female port, ensuring proper orientation of the D-sub shells. Push the connectors straight in until seated; secure any fastening screws on the mating ports if present. Verify function after connection and consult device documentation to confirm signals correspond to the adapter's pin mapping.

Recommendations

Use this adapter only where the specific 9→25 pin mapping matches the required signal routing. Avoid using the adapter in wet or excessively dusty environments without appropriate protection; tighten connector screws to maintain reliable contact and inspect periodically for wear or bent pins.
