DB9 to 3.5mm Serial Cable by StarTech.com, 3ft (1m) RS232 Male for Projector Calibration and Digital Signage (9M351M-RS232-CABLE)

This cable connects devices with a DB9 serial port to those with a 3.5mm audio jack, allowing for serial communication and control. It is commonly used in settings like digital signage, projectors, and TVs that require RS232 control through an audio jack. The cable is ideal for IT professionals or technicians who need to configure or calibrate devices remotely without direct access to a serial port on their computer.

The cable is built with high-quality materials to ensure durability and reliable performance. It uses 28 AWG copper wires with aluminum-mylar shielding to reduce electromagnetic interference. The connectors are shielded and feature molded PVC with strain relief to prevent damage from bending or rough handling. The metal shell and thumbscrew locks on the DB9 connector help secure the connection and prevent accidental disconnection.

This cable is compatible with USB-A and USB-C to DB9 serial adapters, making it useful for computers that lack a built-in serial port. However, a DB9 gender changer may be needed depending on the setup. The 3.5mm end is designed to interface with devices that use a 3.5mm jack for serial control, such as certain projectors and digital signage displays.

The cable is 3.3 feet long and features a black PVC jacket for easy identification and protection against wear. It includes specific pin mappings for the DB9 to 3.5mm connection, ensuring proper signal transmission. The product comes with lifetime technical support, which is valuable for troubleshooting or configuration issues.
