The DeLOCK 84250 is a 5 m grey serial null modem cable with Sub-D9 connectors designed for direct serial communication between two computers or between serial devices. It provides a straightforward wired link for RS-232-compatible equipment and is intended for applications requiring point-to-point serial data transfer with minimal signal degradation.

Advantages

This Sub-D9 null modem cable offers a standard connector format and a practical 5 m length to bridge nearby devices without additional adapters. Its durable construction and shielding help maintain reliable data transmission over the full cable length, while the neutral grey jacket suits a variety of installation environments.

Suitable for

• Connecting two computers via RS-232 serial ports
• Linking serial devices such as modems, routers, POS terminals, and industrial controllers
• Laboratory and workshop setups that require direct serial communication

Key specifications

• Brand: DELOCK
• Model / MPN: 84250
• Connector: Sub-D9 (female/male typical for null modem applications)
• Length: 5 m
• Color: Grey
• Category: Serial & Parallel cables

How to use

Connect each Sub-D9 connector to the corresponding serial port on the two devices. Ensure pins and gender match the devices' ports; if necessary, verify pinout compatibility for specific RS-232 signals. Power on the devices and configure serial communication settings (baud rate, parity, data bits, stop bits, flow control) in each device to match for successful data exchange.

Recommendations

For best results, avoid running the cable alongside high-voltage power lines or sources of electromagnetic interference. Use shielded ports and confirm proper grounding when connecting industrial equipment. If communication issues occur, check connector seating and serial settings before replacing the cable.
