D-Sub Adapter ShiverPeaks COM 913 SC 9-pin to 25-pin

The D-Sub Adapter ShiverPeaks COM 913 SC 9-pin to 25-pin provides a simple mechanical conversion between a 9-pin (DB9) D-Sub connector and a 25-pin (DB25) D-Sub connector. It is intended for signal routing and legacy serial interfaces where physical compatibility is required without changing signal types. The adapter is suitable for use with RS-232 equipment, serial devices, industrial controllers and older peripherals that rely on D-Sub connectors.

Advantages

This ShiverPeaks adapter enables direct connection between DB9 and DB25 devices while maintaining original signal paths. Its compact plastic housing makes it easy to fit in racks, test benches and confined spaces. The adapter preserves pin-to-pin mapping for typical serial applications and avoids the need for rewiring or custom cable fabrication, simplifying integration of legacy devices into modern setups.

Suitable for (tasks / use cases)

• Connecting RS-232 serial devices with differing D-Sub connector sizes
• Integrating legacy peripherals and instrumentation in test benches
• Linking industrial controllers and HMIs that use DB9 or DB25 ports
• Temporary or permanent signal routing where pin mapping is maintained

Key specifications

• Connector type: 9-pin male D-Sub to 25-pin female D-Sub (mechanical adapter)
• Housing material: plastic
• Compatibility: designed for standard D-Sub pin layouts used in serial interfaces
• Intended signals: preserves existing serial signal types (no level conversion)
• Mounting: inline adapter for panel-to-cable or cable-to-cable connections

How to use

Align the DB9 plug of the adapter with the corresponding DB9 receptacle and insert it gently until the connectors seat. Attach the DB25 side to the mating DB25 connector of the device or cable, ensuring correct orientation and secure mechanical engagement. No electrical configuration is required because the adapter does not perform signal conversion; verify that both connected devices use compatible serial signalling (for example RS-232) and matching pinouts before operation.

Recommendations

Use the adapter in dry, indoor environments and avoid exposing it to excessive mechanical stress or moisture. Confirm device pinouts and signal types prior to use to prevent miswiring. For installations requiring secure fastening, use compatible connector screws or strain relief on adjoining cables to minimise movement at the adapter interface.
