Serial extension cable InLine B-12232 — 9-pin inline connector, 2 m length

InLine B-12232 is a 2 m serial extension cable with a 9-pin inline (DE-9) connector designed to extend existing RS-232 serial leads without signal conversion. The cable provides a direct physical link for serial devices such as modems, routers, industrial controllers and legacy PCs where an additional 2 m reach is required. The straightforward design preserves the original signal wiring and pinout, enabling plug-and-play extension of serial connections in office, workshop and industrial environments.

Advantages

The InLine 2 m serial extension cable maintains full compatibility with standard DE-9 RS-232 pinouts and supports straightforward extension without adapters or converters. Its inline 9-pin connector allows simple insertion between two existing serial cables or devices, reducing the need to re-route equipment or relocate hardware. The cable construction offers a balance of flexibility and durability suitable for fixed installations and moderate handling. Because the cable does not perform signal conversion, latency and protocol behavior remain unchanged from the original connection.

Key specifications

• Connector type: 9-pin inline (DE-9) male/female coupling compatible
• Cable length: 2 m
• Interface: RS-232 serial (no signal conversion)
• Wiring: standard RS-232 pinout preserved
• Usage environment: office, workshop, industrial installations

How to use

Insert the inline DE-9 connector between two existing serial cables or plug one end directly into a device and the other end into the mating serial connector. Ensure connectors are aligned and fasten any available thumbscrews or fastening hardware to secure the connection. Verify signal integrity and device communication after installation; because the cable does not change signal levels or protocol, device settings and baud rates remain as configured on the connected equipment.

Recommendations

For reliable operation, route the cable away from high-voltage power lines and sources of electromagnetic interference. Avoid sharp bends and excessive tension on the cable; secure with non-abrasive clamps if used in permanent installations. If longer distances or level shifting are required, use appropriate signal boosters or converters designed for RS-232 communication.
