About the Crestron DM-TX-4KZ-302-C
Inputs switch manually or automatically, and Crestron QuickSwitch HD technology manages HDCP keys for fast, reliable switching, with audio following video. The HDMI inputs accept HDR10, Deep Color, 3D and 4K60 4:4:4 and are compatible with DVI and Dual-Mode DisplayPort, while the DisplayPort input handles Deep Color and 4K60 4:4:4. A local HDMI output (DVI compatible) is provided alongside the DM 8G+ output.
The DM 8G+ output is HDBaseT certified, so it can connect directly to other HDBaseT certified equipment. DM Ultra cable reaches 100 m for all resolutions up to UHD and 4K. DM 8G cable or CAT5e reaches 100 m at 1080p, WUXGA and 2K, and carries UHD and 4K up to 70 m on DM 8G cable or 50 m on CAT5e. It also works with the Crestron Connect It cable caddy.
Power comes over the DM or HDBaseT link as PoDM+ or HDBaseT PoE+ (IEEE 802.3at Type 2 Class 4, 25.5 W), or from the optional PW-2412WU power pack. Typical consumption is 12.6 W on the power pack or 13.4 W on PoDM+ or PoE+, with no USB powered device connected. The black metal chassis has two mounting flanges for freestanding, surface or single rack rail mounting, and is 280 mm high, 136 mm wide and 27 mm deep.
