Serial Cable PremiumCord KLS2-1/5 White 5m DB-9

The PremiumCord KLS2-1/5 is a 5-meter white serial cable with DB-9 (Canon 9F) connectors. It is a crossover (null-modem) cable wired to swap the transmit and receive lines where required, providing dependable serial connectivity for devices that need direct serial communication over a 5 m length.

Advantages

This crossover serial cable uses DB-9 Canon 9F connectors and a defined crossover wiring (1-1, 2-3, 3-2, 4-6, 5-5, 6-4, 7-8, 8-7, 9-9, S-S), ensuring compatibility with equipment that requires null-modem connections. The 5 m length offers flexibility for desktop or rack installations while the white jacket provides a neat appearance and easy identification. The cable is suitable for stable, point-to-point serial links where simple, reliable data transfer is needed.

Suitable for

• Connecting serial devices that require crossover/null-modem wiring
• Linking computers, routers, switches, or industrial controllers with DB-9 ports
• Temporary or semi-permanent installations where a 5 m reach is needed

How to use

Connect each DB-9 (Canon 9F) connector to the serial ports of the two devices you want to link. Ensure both devices are powered off when connecting or disconnecting to avoid port issues. After physical connection, power the devices and configure serial port parameters (baud rate, parity, data bits, stop bits, flow control) in the devices' settings so they match on both ends. The crossover wiring handles TX/RX swapping internally, so no additional adapter is required for null-modem communication.

Usage recommendations

Use this cable for direct device-to-device serial communication where a null-modem configuration is needed. Avoid routing near high-power AC lines or strong electromagnetic sources to reduce interference. For outdoor or harsh environments, consider a cable with additional shielding or protective jacket.
