1T-CT-611 Transmitter & 1T-CT-612 Receiver provide all digital, zero loss transmission of HDMI version 1.3a signals at resolutions up to 1080p over Cat.6 cable. This is an all digital system, so the transmission distance varies with the resolution transmitted. 1080i HDTV signals can achieve distances up to 75 meters (220 feet) between the transmitter and receiver. For normal operation, two Cat.6 cables are required, one for the HDMI signal and one for the HDCP/DDC signal. Single cable operation is possible when HDCP and DDC are not needed. Signal Boost and Equalization adjustments via dipswitches are provided. The system is fully compatible with DVI-D signals. Locking power connectors are used to enhance overall system security.
