Serial cable ShiverPeaks 3 m, 9-pin Sub-D, model 78041-3

The ShiverPeaks 3 m serial cable with a 9-pin Sub-D connector (model 78041-3) is a shielded, molded plug-to-plug cable designed for RS-232/serial communication. It provides a reliable wired link for data transfer and control signals between devices that use a standard 9-pin D‑sub interface. The 3-meter length balances reach and signal integrity for typical industrial, commercial and legacy equipment setups.

Advantages

This serial cable uses standard 9-pin Sub-D connectors with molded, strain-relief ends to reduce connector stress and maintain a stable connection. The cable assembly is suitable for continuous use in fixed or semi-mobile installations and is built to preserve signal quality over the 3 m distance. Compatibility with RS-232 interfaces ensures straightforward integration with a wide range of controllers, point-of-sale terminals, modems and other serial peripherals.

Suitable for

• Connecting industrial controllers, PLCs and instrumentation to host computers
• Linking POS systems and receipt printers to serial ports
• Establishing communication with external modems and telemetry devices
• Interfacing legacy peripherals such as barcode scanners and label printers

Key specifications

• Cable length: 3.0 m
• Connector type: 9-pin D‑sub (Sub-D / DB9) male-to-male, molded
• Interface standard: RS-232 (serial)
• Construction: shielded cable with strain relief
• Mounting style: plug-to-plug for direct device-to-device connection

How to use

Inspect both device ports to ensure they are compatible 9-pin D‑sub serial ports and power off equipment if recommended by the manufacturers. Align each DB9 plug with the corresponding socket and secure any fastening screws by hand to avoid over-tightening. After connection, power on the devices and set matching serial parameters (baud rate, parity, data bits, stop bits, flow control) in the device settings or software to establish communication.

Recommendations

For stable RS-232 communication, keep cable runs free from high-voltage cables and strong electromagnetic sources. Use appropriate serial configuration settings and, if necessary, confirm pinout compatibility when connecting devices from different manufacturers.
