StarTech SCNM9FM 10ft RS232 Serial Null Modem Cable F/m
Overview
The StarTech SCNM9FM is a 10-foot (3-meter) RS-232 serial null modem cable designed to facilitate direct communication between two serial devices. This cable is essential for connecting legacy equipment, industrial controllers, or diagnostic tools that rely on serial ports, enabling them to exchange data directly without requiring modems. Its gender-changing capability (female-to-male) simplifies connections in environments where specific port types are required on each end. The 28 AWG wire gauge ensures reliable signal transmission over its length.
Compatibility
This null modem cable is compatible with any device featuring standard 9-pin (DB-9) RS-232 serial ports. It is commonly used for connecting devices such as industrial automation equipment, point-of-sale systems, network switches for console access, and older computing hardware. The 7-conductor wiring supports common serial communication protocols.
Installation Notes
The cable features standard DB-9 connectors, one male and one female, with a gray PVC jacket for durability. Its 10-foot length provides sufficient reach for most desk-based or rack-mounted equipment setups. Ensure that both connected devices are powered off before making or breaking connections to prevent potential data corruption or hardware damage.
