Product information

Description

The ATEN CE840-AT-G is a wired KVM extender consisting of a local (transmitter) unit and a remote (receiver) unit that transmits uncompressed True 4K HDMI video, audio, RS232, Ethernet and USB signals up to 100 m over a single Cat 6A cable. Using HDBaseT 3.0 technology, the extender supports HDR10+ and delivers video up to 3840 x 2160 @ 60 Hz 4:4:4 and 4096 x 2160 @ 60 Hz 4:4:4 with zero compression and zero latency. Each unit includes an HDMI output for local monitoring, multiple USB 2.0 ports for peripherals, and LEDs and pushbuttons to switch USB console control between local and remote ends.

Advantages

The CE840 provides lossless AV transmission and low-latency control over a single Cat 6A cable, simplifying installation and reducing cabling cost. Dual-console operation is supported with two USB ports for keyboard and mouse and pushbutton switching for console control. The extender carries multiple signal types (HDMI video, audio, USB, RS232, and Ethernet) through one link, and supports common HDMI audio formats including LPCM 7.1CH, Dolby TrueHD, Dolby Digital Plus and DTS-HD Master Audio.
