## Summary description

ShiverPeaks 78420 is a Sub-D adapter that converts a 9‑pin (DE‑9) connector to a 25‑pin (D‑Sub 25) connector. It functions as a gender/connector type adapter for serial and legacy D‑Sub interfaces, allowing connection between devices with different Sub‑D pin counts. Suitable for testing, legacy equipment integration, and serial communication setups.

## Long description

ShiverPeaks 78420 is a compact Sub-D gender changer that converts a 9-pin (DE-9) connector to a 25-pin D‑Sub 25 connector. Designed for serial and legacy D‑Sub interfaces, this adapter enables physical connection between equipment with different Sub-D pin counts without changing the cabling or ports on connected devices. The adapter is made of plastic housing with metal contacts to ensure basic mechanical alignment and signal continuity for standard non-powered serial links.
Advantages
The adapter provides a quick and reversible way to connect DE-9 and D‑Sub 25 connectors without soldering or rewiring. Its compact form factor and light-weight plastic construction make it easy to carry and fit in restricted spaces. The simple gender-changing function preserves pin mapping for common serial configurations and reduces the need for custom cables when integrating legacy devices.
Suitable for
 Connecting devices with 9-pin serial ports to equipment using 25-pin D‑Sub ports
 Field testing and bench diagnostics of legacy serial hardware
 Temporary or permanent interface adaptation in industrial and laboratory setups
 Integration of older peripherals with modern systems that retain D‑Sub connectors
Key specifications
 Connector conversion: DE-9 (female/male orientation as adapter) to D‑Sub 25
 Housing material: plastic
 Contact material: metal contacts designed for low-voltage signal transmission
 Form factor: compact, lightweight gender changer
 Intended use: passive mechanical adapter for signal routing (no power conversion)
How to use
Align the DE-9 side of the adapter with the device's 9-pin serial connector and gently insert until the mating faces are fully engaged. Attach the D‑Sub 25 side to the corresponding 25-pin connector of the other device, ensuring screws or thumbscrews (if present on the mating connectors) are secured to prevent accidental disconnection. The adapter requires no drivers or power; it functions as a passive mechanical interface. Verify pin mapping and signal compatibility for your specific equipment before applying communication protocols.
Usage recommendations
Use the adapter for signal-level serial connections only and avoid exposing it to moisture, excessive mechanical stress, or environments with strong electromagnetic interference. For applications requiring shielding, power conversion, or specific pin remapping, consider using purpose-built cables or active converters.
