PTM-RS135 – RS232 Control Cable: 3.5mm Jack to DB9 for Device Management
The PTM-RS135 is a dedicated RS232 control cable designed for integration between AV control systems and RS232-capable equipment in environments such as meeting rooms, control rooms, and workspace installations. Featuring a 3.5mm TRS connector at one end and a 9-pin D-Sub (DB9 female) at the other, the cable provides a fixed pin assignment to ensure consistent communication protocols. Each unit undergoes comprehensive electrical testing, supporting reliable device management and streamlined signal routing in professional AV deployments where stable serial connectivity is required.

• 1.5m Cable Length: The cable offers a 1.5 metre reach, supporting flexible placement of control hardware and end devices within AV racks, lecterns, or behind displays. This length accommodates standard installation distances without excess slack or signal degradation.

• 3.5mm TRS to DB9 Connectivity: Equipped with a 3.5mm tip-ring-sleeve (TRS) connector and a 9-pin D-Sub (DB9 female), the cable enables direct interfacing between compact controllers and traditional RS232 ports. This configuration supports integration with a range of control processors and AV endpoints.

• Fixed Pin Assignment: The cable utilises a predetermined pinout, ensuring reliable RS232 signal mapping between the 3.5mm jack and DB9 connector. This reduces installation errors and maintains consistent communication standards across multiple deployments.

• Electrical Testing Assurance: Each cable is 100% electrically tested prior to shipment. This process verifies continuity and pin integrity, minimising the risk of field failures and supporting dependable performance in mission-critical AV setups.

• RS232 Device Compatibility: Designed for use with RS232-capable devices, the cable supports a wide spectrum of professional AV hardware, including matrix switchers, projectors, and control processors, facilitating straightforward integration in both new and legacy systems.
