PT-CON-PEX110 – Network Serial Port Expander: IP-Based Control Integration for Legacy AV Devices
The PT-CON-PEX110 network-to-serial and I/O expander is engineered to facilitate the integration of legacy or standalone AV equipment into modern IP-based control systems. Its architecture incorporates a 100M Ethernet interface with mDNS support, enabling streamlined device discovery and network configuration in diverse AV environments. The unit provides RS-232 and RS-485 serial ports, I/O, and IR output, supporting a wide range of control scenarios for projectors, displays, switchers, lighting, and audio systems. Port parameters are accessible via a web interface or API, which simplifies configuration for AV integrators and support personnel. Flexible power options, including PoE and 24V DC, allow deployment in space-constrained or retrofit installations such as meeting rooms, classrooms, auditoriums, hospitality venues, control rooms, and digital signage setups.

• 100M Ethernet Network Interface: The integrated 100M Ethernet port supports reliable IP-based communication and device management. mDNS (Multicast DNS) functionality enables automatic device discovery, reducing manual configuration and network setup time in both new and existing AV control networks.

• RS-232 and RS-485 Serial Control: Dedicated RS-232 and RS-485 ports facilitate direct serial communication with a wide range of legacy AV devices. This supports integration of displays, projectors, switchers, and other equipment that require serial protocols for command and status feedback.

• I/O and IR Output for Device Control: The unit includes a configurable I/O port and an IR output, providing versatile options for controlling relays, screens, lighting, or IR-operated devices. This enables comprehensive system control from a single networked interface, suitable for mixed-technology environments.

• Configurable Port Parameters: All control port parameters can be configured via an embedded web interface or through an API. This feature streamlines setup and adjustment, allowing integrators to adapt device behaviour remotely without physical access to the hardware.

• Flexible PoE or DC Powering: The device supports both Power over Ethernet (PoE) and 24V DC input, enabling deployment in locations with limited cabling or power availability. This flexibility simplifies installation in retrofit projects and distributed AV system layouts.

Comprehensive Network Control Expansion for AV Systems
By combining Ethernet, serial, I/O, and IR interfaces with remote configuration and flexible power options, the PT-CON-PEX110 enables seamless integration of non-networked AV devices into IP-based control infrastructures. This unit provides a practical solution for extending system control and centralising management across diverse environments, supporting both new installations and upgrades of existing AV deployments.
