HDCP 2.2 compliance, EDID management, and PoE for remote receiver powering. A wide variety of
consumer and commercial displays may be controlled by the AT-UHD-CAT-4 / AT-UHD-CAT-8 using
CEC. Designed for commercial or residential distribution applications, both the AT-UHD-CAT-4 /
AT-UHD-CAT-8 are control system-friendly and integrate with any TCP/IP, RS-232, or IR control
system. Both units feature a 1U, full-rack width enclosure with external, international power
