The HT-TX01 HDBaseT Transmitter from Roland transmits an HDMI signal to an HT-TX01 transmitter (sold separately) up to 328 ft over a shielded CAT5e or higher Ethernet cable. This makes it possible to connect video cameras, Blu-ray decks, switchers, and other source equipment to LCD monitors, projectors, and other display devices. RS-232C control signals can be extended along with video and audio signals, reducing system wiring.
