This 1-meter cable allows you to connect a control unit with a DB9 port to devices equipped with a 3.5mm audio jack. It is intended for remote configuration and calibration tasks via the RS232 serial protocol, facilitating communication between control equipment and devices such as TVs, projectors, or digital signage displays that use this type of connector for service functions.

The construction includes aluminum-mylar shielding and connectors with metal housings to reduce electromagnetic interference. The DB9 connectors feature thumb screws to ensure secure attachment and prevent accidental disconnections, while molded PVC strain reliefs protect against abrasion damage. The pinout assigns the transmit signal to the ring, receive to the tip, and ground to the sleeve of the 3.5mm connector.
