Sub-D cable ShiverPeaks 78042-5, 2 × 9-pin (DB9), 5 m length

Sub-D cable ShiverPeaks 78042-5 is a 5 m serial cable with two 9-pin (DB9) connectors designed for RS-232 and other standard serial interfaces. The cable provides a fixed-length wired connection between devices such as computers, routers, industrial controllers and legacy peripherals. It is intended for data transfer, device configuration and diagnostic communication where a conventional DB9 serial link is required.

Advantages

This Sub-D cable offers a straightforward, reliable connection using standard 9-pin connectors that are widely supported by serial devices. The molded connector housings increase mechanical stability and strain relief at the cable ends, helping to reduce connector damage and intermittent contacts. With a 5 m length, the cable balances reach with signal integrity for typical serial communication distances without requiring repeaters or converters.

Suitable for

• Connecting RS-232 serial devices such as modems, routers, and serial printers
• Linking computers or terminals to industrial controllers and PLCs for configuration
• Diagnostics and maintenance tasks that require a direct DB9 serial interface
• Legacy peripherals and instrumentation that use 9-pin Sub-D ports

Key specifications

• Connector type: 2 × 9-pin Sub-D (DB9)
• Cable length: 5.0 m
• Housing: molded connector shells for strain relief and mechanical protection
• Intended interface: RS-232 / standard serial signaling
• Cable form: fixed-length, shielded serial cable (single-run)

How to use

Connect each DB9 connector to the corresponding serial port on the devices to be linked, ensuring correct orientation and secure tightening of any thumbscrews or fastening elements if present. Configure serial parameters (baud rate, parity, data bits, stop bits, flow control) on both devices to match before initiating communication. For diagnostic sessions, use terminal software or vendor-specific tools to establish and monitor the serial link. When disconnecting, loosen connectors carefully to avoid twisting the cable.

Recommendations

For reliable operation, avoid routing the cable near strong electromagnetic sources and high-voltage power lines; maintain modest bends and do not exceed the cable's mechanical limits. Use the 5 m length for direct device-to-device connections; for longer runs or environments with high electrical noise consider using repeaters, isolated converters or alternative interfaces. Inspect connector housings periodically for wear and ensure thumbscrews or fasteners remain tight to preserve a stable serial connection.
