PT-C-HDCEC – In-line HDMI Controller 4K: Automated Signal and Device Control for Meeting Spaces
The PT-C-HDCEC 18G In-line HDMI Controller is engineered for automatic system control and HDMI signal extension within small meeting rooms and huddle spaces. Its architecture integrates multiple control pathways, including IR, RS-232, CEC, and relay, enabling flexible automation based on sensor input or HDMI signal events. The unit supports advanced video formats, including HDR10 and Dolby Vision, and down-scaling for compatibility with legacy displays. Comprehensive EDID management and built-in signal equalisation facilitate reliable operation across a range of professional AV environments, supporting both direct and sensor-activated workflows.

• Multi-Protocol Trigger Integration: The controller processes incoming control signals—CEC, RS-232, IR, and relay—triggered by either sensor input or HDMI signal events. This enables seamless automation of device power, input selection, and environmental controls in meeting or classroom installations.

• 4K 60Hz Video and Signal Extension: Supports HDMI 2.0a with data rates up to 18Gbps, accommodating video resolutions up to 4K UltraHD at 60Hz 4:4:4. HDR10 and Dolby Vision compatibility ensures accurate signal delivery to modern displays in AV environments requiring high-fidelity image reproduction.

• Integrated 4K to 1080p Downscaling: The built-in scaler converts 4K video to 1080p output, maintaining compatibility with legacy or mixed-resolution display devices. This function is essential for hybrid environments where both UHD and Full HD screens are present.

• EDID Management and HDCP Flexibility: Eight selectable EDID presets are accessible via DIP switch, supporting tailored signal negotiation for diverse AV setups. The unit passes HDCP or converts HDCP 2.2 to 1.4, ensuring content protection compatibility across a wide range of display hardware.

• Sensor and Relay Integration: Contact closure input allows connection of external sensors or buttons, providing versatile control triggers. Dual relay outputs facilitate automation of peripherals such as projection screens, supporting fully integrated meeting room or classroom control schemes.

Automated AV Control and Signal Management
By combining multi-protocol control, advanced video processing, and sensor-triggered automation, the PT-C-HDCEC serves as a central point for unified AV system management. This unit provides reliable signal extension, flexible device control, and seamless integration of environmental triggers, supporting efficient deployment in professional meeting spaces and collaborative environments.
