Sub-D-adapter ShiverPeaks 9-polig naar 25-polig – gender changer voor RS-232-apparaataansluiting

Sub-D Adapter ShiverPeaks 9-pin to 25-pin is a passive gender adapter designed to convert a DE-9 (Sub-D/9) connection to a DB-25 (Sub-D/25) connection for serial communications such as RS-232. The compact plastic housing provides a simple mechanical interface that preserves signal wiring and allows direct pin-to-pin passthrough between devices with different Sub-D pin counts. This adapter is intended for situations where a cable or port with a 9-pin Sub-D must be connected to equipment expecting a 25-pin Sub-D without altering signal routing.

Advantages

The adapter offers straightforward compatibility between DE-9 and DB-25 connectors without the need for active electronics or re-wiring. Its passive design ensures that data lines are passed through without introducing signal conversion or latency. The lightweight plastic shell reduces strain on connector pins and provides a durable, low-cost solution to bridge legacy RS-232 interfaces and instruments with differing Sub-D form factors.

Suitable for

• Connecting legacy RS-232 devices with DE-9 ports to equipment with DB-25 ports
• Linking instruments, modems or serial terminals that use different Sub-D pin counts
• Temporary or permanent wiring compatibility in test benches and industrial setups

Key specifications

• Connector types: female DE-9 to female DB-25 (Sub-D)
• Function: passive pin-to-pin adapter for serial signal passthrough
• Housing material: plastic
• Form factor: compact inline adapter for direct coupling of Sub-D connectors
• Signal standard: intended for use with RS-232 and compatible serial interfaces

How to use

Align the DE-9 and DB-25 connectors with the corresponding ports and push the adapter straight onto the connector until it seats securely. If the equipment uses fastening screws, secure the adapter by tightening the thumb screws or enclosure screws to prevent accidental disconnection. Ensure both devices are powered off when connecting or disconnecting to reduce risk of spurious signals; verify wiring compatibility if non-standard pin assignments or custom cables are present.

Recommendations

Use the adapter in dry, indoor environments and avoid exposure to excessive mechanical strain or moisture. For installations requiring signal conversion, level shifting, or null-modem functionality, use a dedicated converter or specially wired cable rather than a passive adapter. Periodically inspect connector contacts for corrosion or deformation to maintain reliable serial communication.
