Serial interface cable HP 8ft — 8-foot (approx. 2.44 m) serial cable for RS-232 connections

HP 8ft Serial interface cable is an 8-foot (approximately 2.44 m) serial cable designed for RS-232 style serial connections between computers, routers, switches, POS terminals and legacy equipment. It provides a standard wired interface for data transmission and device management, suitable for console access, configuration and diagnostics of network hardware and industrial devices. The cable length offers flexible placement of connected equipment while maintaining signal integrity for short-range serial communication.

Advantages

This HP serial cable offers a stable physical connection for RS-232 communication with a length that balances reach and signal reliability. Its compatibility with common serial ports enables straightforward integration with older hardware and network gear used for configuration or troubleshooting. The cable is suited for use in environments where a simple, direct connection is preferable to complex adapters or wireless interfaces.

Suitable for

• Console access and configuration of routers and switches
• Connecting POS terminals and receipt printers to control systems
• Diagnostic and maintenance connections for legacy equipment
• Serial communication between computers and industrial devices

Key specifications

• Type: RS-232 serial cable
• Length: approximately 8 ft / 2.44 m
• Connector style: standard serial connectors for RS-232 devices
• Application: data transmission, console management, device configuration and diagnostics

How to use

Connect one end of the cable to the RS-232 serial port on the computer or console device and the other end to the serial port of the target device such as a router, switch, POS terminal or industrial controller. Ensure both devices are powered off or set to the appropriate communication settings before connecting. After connecting, power the devices and launch the terminal or management software on the host system, configure the serial port parameters (baud rate, data bits, parity, stop bits and flow control) to match the target device, and establish the session for configuration, diagnostics or data transfer.

Usage recommendations

Use this cable for short-range serial connections in controlled environments. Avoid running the cable near high-voltage power lines or sources of strong electromagnetic interference. Verify connector polarity and pinout compatibility with your devices before use; if pinout differences exist, use a suitable adapter or null-modem arrangement as required.
