Serial Link Cable ROLINE DB9 F - F 1.8 m

The ROLINE Serial Link Cable DB9 F - F 1.8 m is a grey, shielded null-modem cable with two 9-pin D-Sub female connectors. It is intended to connect two PCs or other devices equipped with DB9 serial ports for direct serial communication, providing stable data transmission and reduced electromagnetic interference.

Advantages

The cable uses a null-modem wiring to enable direct device-to-device communication without a modem. Molded connector casings with special plastic provide strain relief to reduce the risk of cable breakage. Good shielding minimizes data loss and protects against electromagnetic interference, supporting reliable serial connections.

Suitable for

• Connecting two PCs via RS-232 serial ports
• Direct connections between computers and serial peripherals (e.g., printers, routers, industrial devices)
• Data transfer and configuration tasks that require DB9 female-to-female null-modem cabling

Key specifications

• Length: 1.8 m
• Connectors: 2 × DB9 (9-pin D-Sub) female
• Wiring: null-modem pinout
• Colour: grey
• Brand / MPN / EAN: ROLINE / 11.01.9018 / 7611990110384

How to use

Plug each DB9 female connector onto the corresponding male DB9 serial port of the devices you want to connect. Ensure the devices are powered off or in a safe state before connecting. After physical connection, configure the serial communication parameters (baud rate, parity, data bits, stop bits, flow control) on both devices to match. Use the cable for direct data transfer, device configuration, or diagnostic communication according to your equipment's instructions.

Usage recommendations

For reliable operation, keep cable runs short and avoid routing the cable near strong electromagnetic sources. Verify pinout compatibility with your devices and match serial settings on both ends before starting communication.
