Serial cable DELOCK RS-232 D-Sub 9 female–female 1.8 m null modem, beige, 5 mm diameter

This Delock null modem cable allows direct serial communication between two computers or between serial devices. The cable is designed for RS-232 connections and provides a straight DB-9 male connector on both ends, enabling simple peer-to-peer data transfer without a modem.

Advantages

The cable offers a straightforward solution for establishing direct serial links. With identical DB-9 male connectors on both ends and standard 28 AWG wiring, it is compatible with many legacy serial ports and is simple to install. Its 1.8 m length gives flexibility in device placement while the neutral beige color matches common equipment.

Key specifications

• Length: 1.8 m
• Connectors: DB-9 Male (straight) — both ends
• Wire gauge: AWG 28
• Color: Beige

How to use

Connect each DB-9 male connector to the corresponding serial port on the two devices. Ensure serial port settings (baud rate, parity, data bits, stop bits, and flow control) are configured identically on both devices before initiating communication. No additional drivers are required for a passive null modem cable; verify physical connection and signal pinout if communication fails.

Recommendations

Use this cable for short-distance direct serial communication between computers or serial devices. For longer distances or environments with electrical interference, consider using shielded cables or alternative serial extenders.
