Description

StarTech SCNM9FM2MBK DB9 Null Modem Cable

Overview

The StarTech SCNM9FM2MBK is a 2-meter (6.6 ft) DB9 null modem cable designed to directly connect two serial devices, facilitating file transfers or device configuration. This cable is essential for legacy equipment or specific industrial automation setups where direct serial communication is still the standard. The SCNM9FM2MBK uses a standard DB9 connector on both ends, with internal wiring configured for a null modem connection, meaning the transmit and receive lines are crossed over. This setup allows two DTE (Data Terminal Equipment) devices to communicate as if they were connected to a modem (DCE - Data Communications Equipment).

Compatibility

This null modem cable is compatible with any devices featuring standard DB9 serial ports, including many industrial controllers, network switches, routers, diagnostic tools, and older computing hardware. It is suitable for direct PC-to-PC file transfer applications or connecting a PC to a serial device for configuration and control, such as with certain network infrastructure equipment or specialized industrial machinery.

Installation Notes

The cable is constructed with 28 AWG wire, providing sufficient conductivity for standard serial communication speeds. It operates reliably within a wide temperature range of -20°C to 80°C (-4°F to 176°F) and can handle humidity levels from 15% to 65% RH, making it suitable for various deployment environments. The connectors are designed for a secure fit, preventing accidental disconnections during operation.
