Cable ShiverPeaks 78065-2 9-pin Sub D (DB9) coupling to 25-pin (DB25), length 2 m

ShiverPeaks 78065-2 is a 2 m interface cable that connects a 9-pin Sub D (DB9) coupling on one end to a 25-pin Sub D (DB25) connector on the other. It is intended for routing serial and legacy parallel signals between DB9 and DB25 devices, supporting straightforward adapter-style connections in industrial, laboratory or office environments. The cable implements a fixed wiring scheme for common RS-232 and legacy modem interconnections and is supplied with snap-on hoods for secure connector cover.

Advantages

This DB9-to-DB25 cable provides a compact, single-cable solution for linking equipment with differing Sub D interfaces, avoiding the need for separate adapters or complex rewiring. Its 2 m length offers a balance between reach and cable management in bench and rack installations. Snap-on hoods help keep the connector shells closed and reduce strain on the connector pins during handling and session changes. The cable's nine-conductor construction ensures individual signal continuity for typical serial and modem wiring schemes.

Suitable for

• Connecting RS-232 serial devices with DB9 ports to equipment or adapters using DB25
• Legacy modem and telecommunications connections requiring DB9/DB25 interfacing
• Laboratory instrumentation or test benches that combine devices with different Sub D connectors
• Office or industrial systems where a direct DB9-to-DB25 link simplifies setup

Key specifications

• Cable length: 2.0 meters
• Connector A: 9-pin Sub D (DB9) coupling / female
• Connector B: 25-pin Sub D (DB25) plug / male
• Conductor count: 9 cores
• Connector housings: snap-on hoods for strain relief and shell protection
• Typical use: serial and legacy modem signal routing

How to use

Inspect both the DB9 and DB25 connectors on the devices you intend to link to ensure they match the cable’s coupling and plug orientations. Align the DB25 plug with the device socket and insert gently, securing the connector with the provided thumbscrews or snap-on hood as applicable. On the DB9 side, mate the coupling connector to the device or adapter and close the hood to hold the connection. Route the cable to avoid sharp bends and strain points; keep it away from high-voltage lines and strong electromagnetic sources to minimize interference. If connecting modem or RS-232 equipment, verify signal pinouts and any required handshaking options before use.

Recommendations

For reliable operation, avoid excessive bending near the connector ends, secure the cable with appropriate cable ties or fasteners to reduce mechanical stress, and confirm device pinouts where non-standard wiring may be present. Periodically check connector hoods and thumbscrews for tightness and inspect conductors for wear if the cable is used in a high-movement environment.
