Serial cable StarTech 0.5 m DB9 RS232 straight-through, male to female, black

The StarTech 0.5 m DB9 RS232 straight-through serial cable (male to female) in black provides a compact, standard-pinout connection for RS232 devices. With a 0.5 metre cable length and one DB9 male and one DB9 female connector, this cable supports direct device-to-device serial data transfer and extends the reach of modems, routers, POS systems, industrial equipment and legacy PCs where a short extension or replacement of an existing serial lead is required.

Advantages

This straight-through DB9 serial cable uses the standard RS232 pinout for direct compatibility with a wide range of serial equipment. The short 0.5 m length reduces excess cable clutter while allowing flexible device placement. The cable is constructed from durable materials and includes shielding to help reduce EMI interference. It is supplied as a single-piece pack in black, suitable for professional and legacy serial applications.

Suitable for

• Extending the physical reach between RS232 serial devices by up to 0.5 m
• Connecting modems, routers or legacy PCs with DB9 serial ports
• POS systems and point-of-service peripherals with DB9 serial interfaces
• Industrial devices and instrumentation that use RS232 serial communication

Key specifications

• Cable length: 0.5 m
• Connector types: DB9 male to DB9 female
• Pinout: RS232 straight-through (standard DB9 pinout)
• Color: black
• Pack: single-piece

How to use

Connect the DB9 male end to the female DB9 port on the host device and plug the DB9 female end onto the male connector of the peripheral. Ensure connectors are fully seated and, if present, secure any thumbscrews to maintain a stable connection. The cable uses a straight-through RS232 pinout so no adapters or null-modem wiring is required for standard device-to-device serial communication.

Usage recommendations

For reliable serial communication, keep cable runs free from large sources of electrical noise and avoid sharp bends near the connector ends. Use this 0.5 m extension to reduce excess length and improve cable routing; for longer distances select a cable rated for the required run length and installation environment.
