Serial Cable DeLOCK Sub-D9 1.8m Grey 84077

Serial cable with Sub-D9 (9 pin) female connectors, length 1.8 m, designed for direct serial communication between two computers or other devices with a Sub-D9 interface. The DELOCK model 84077 in grey provides a straightforward wired connection for RS‑232 serial data transfer and is suitable for office and industrial environments where a null modem configuration is required.

Advantages

The cable uses two 9‑pin female Sub‑D connectors wired in a null modem arrangement to allow device‑to‑device communication without a modem. At 1.8 m length it offers flexible placement while maintaining signal integrity. The grey jacket and robust construction make it suitable for repeated use in typical office and industrial setups.

Suitable for

• Point‑to‑point serial communication between two computers
• Connection of serial devices such as industrial controllers, POS terminals or measurement equipment
• Legacy equipment with Sub‑D9 RS‑232 ports

Key specifications

• Brand: DELOCK
• Model / MPN: 84077
• Connector: Sub‑D9 female to Sub‑D9 female (null modem wiring)
• Length: 1.8 m

How to use

Connect each 9‑pin female Sub‑D connector to the corresponding male serial port on the devices to be linked. No additional adapters are required for standard Sub‑D9 ports. Configure serial communication parameters (baud rate, parity, data bits, stop bits) in each device or host software to match the remote device. The null modem wiring handles transmit/receive crossover internally for direct device communication.

Usage recommendations

For reliable operation, avoid sharp bends and excessive tension on the cable; keep cable length appropriate for your setup and ensure device serial settings match. If communication issues occur, verify pinout compatibility with connected devices and check for proper null modem wiring.
