Sarjaportin jatkokaapeli InLine B-12235 — 9-napainen InLine RS-232, 5 m

InLine B-12235 is a 5 m serial extension cable with a 9‑pin inline connector designed for RS‑232 connections. The cable extends an existing serial link without requiring changes to connected devices, enabling continuous wired communication between equipment over short to medium distances. Its construction maintains signal integrity for common serial applications and fits standard 9‑pin D‑sub RS‑232 setups used in modems, industrial controllers and legacy peripherals.

Advantages

The cable delivers a straightforward physical extension of RS‑232 ports while preserving pin assignment and signal routing, which avoids reconfiguration of devices. With a 5 meter length, it balances reach and signal reliability for typical office and industrial layouts. The inline 9‑pin connector enables a clean, pass‑through connection that is compatible with standard D‑sub 9 serial ports and supports stable wired data transfer for control and communication tasks.

Suitable for

• Extending connections between computers and external modems
• Connecting POS terminals and receipt printers to serial controllers
• Linking industrial controllers, PLCs and instrumentation with RS‑232 interfaces
• Integrating legacy serial peripherals into modern setups without port modifications

Key specifications

• Connector type: 9‑pin inline D‑sub for RS‑232
• Cable length: 5 m
• Signal standard: RS‑232 serial communication
• Usage: passive extension, maintains pinout and signal routing
• Typical application distance: short to medium range wired transmission

How to use

Disconnect power to devices before connecting serial cabling. Plug the inline 9‑pin connector into the existing serial port or extension lead, and then attach the opposite end to the device you want to reach. Ensure connectors are fully seated and, if applicable, secure screws to prevent accidental disconnection. Restore power and verify communication settings such as baud rate, parity and flow control in connected devices to match the remote equipment.

Recommendations

For reliable RS‑232 performance, keep cable runs away from strong electromagnetic sources and AC power wiring where possible. Use straight, untwisted routing with gentle bends to avoid strain on connectors. For installations in electrically noisy environments or longer distances, consider signal repeaters, shielded alternatives or converting to a differential interface to maintain communication quality.
