The ATEN CE801 is a USB HDMI KVM extender that transmits HDMI video, USB keyboard/mouse signals, digital audio and RS-232 serial control between a local source and a remote console over a single Cat 6 cable. The extender supports True 4K (3840 x 2160 @ 60 Hz, 4:4:4) up to 70 m and a Long-Reach Full HD mode up to 100 m. Both transmitter (CE801L) and receiver (CE801R) provide HDMI video and USB Type-A ports for local console connections, and the devices are rack-mountable with a secured DC jack for stable power delivery.

Advantages

The CE801 delivers uncompromised True 4K video with HDR up to 70 m and offers a Long-Reach mode for 1080p extension up to 100 m, all over a single Cat 6 cable. It supports dual-console operation with a local-priority pushbutton, EDID switching for optimal video output on both consoles, RS-232 serial communication for remote device control, and built-in ESD protection. The metal housing is compact and rack-mountable, and the DC jack features a screw-lock to prevent accidental disconnection.

How to use

Connect the source computer's HDMI and USB ports to the CE801L transmitter and place the CE801R receiver near the remote console. Run a single Cat 6 cable between the transmitter and receiver up to the supported distance (True 4K up to 70 m or FHD long-reach up to 100 m). Connect local keyboard and mouse to the USB Type-A ports on either unit as required. If needed, configure EDID switches on the transmitter to match desired display output and use the pushbutton to set local-priority or auto KVM control. For serial control, connect a serial device to the receiver's RS-232 port and send commands from a serial terminal connected to the transmitter.

Recommendations

Use a straight, high-quality Cat 6 cable for best video and USB performance. For True 4K at 70 m ensure HDMI sources and displays support 4K @ 60 Hz and HDCP 2.2/2.3; switch to Long-Reach mode for stable Full HD extension up to 100 m. Secure the DC adapter with the screw-lock to avoid accidental disconnection and place the units in a ventilated rack or enclosure to maintain reliable operation.
