The Extron HCT 103 is a Meeting Space Collaboration System transmitter. It is part of the Extron HC 404 system, which includes the HCT 103 transmitter and an HCR 102 receiver.

Key functions and features of the HCT 103 transmitter include:

Switching: It acts as a switcher for HDMI and VGA sources, allowing selection between two HDMI inputs and one analog VGA input.

Audio Handling: It handles associated digital and analog audio, including embedding analog audio onto the digital video output.

Signal Extension: It facilitates signal extension over shielded CATx cable, sending the selected video and audio to a matching HCR 102 receiver up to 230 feet (70 meters) away.

HDCP Compliance: If the selected input is HDMI, the extended video signal can be HDCP-compliant.

Automatic Switching: It offers configurable automatic switching modes between inputs, including "last connected" (most recent active input) and priority-based switching.

EDID Management: It provides automatic EDID management, ensuring proper communication between connected devices and offering pre-stored or user-uploaded EDID files.

Control Options: It includes front panel controls for input selection and alternatives for configuration and operation through product configuration software connected via Ethernet.
