## Summary description

The ATEN VE1821-AT-G is an AV transmitter and receiver supporting a maximum resolution of 4096 x 2160 pixels. It uses wired connectivity with Cat5e and Cat6 cables. The receiver and transmitter both have compact dimensions of 68 x 79.5 x 16.5 mm and weigh 120 g. Power consumption is low, with the receiver at 0.87 W and the transmitter at 1.86 mA, making it efficient for AV applications.

## Long description

The ATEN VE1821-AT-G AV transmitter and receiver kit extends HDMI video up to 4096 x 2160 / 3840 x 2160 @ 30 Hz (4:4:4) over a single Cat 6 cable up to 40 m (ATEN 2L-2910 recommended). The compact kit includes a transmitter and a receiver in palm-sized enclosures and supports lossless multi-channel audio formats such as LPCM 7.1CH, Dolby TrueHD, Dolby Digital Plus, and DTS-HD Master Audio. The transmitter offers a local HDMI output for monitoring or cascading and an EDID switch with EDID Copying Mode to ensure the HDMI source is displayed at the optimal resolution for the connected display. The VE1821 also supports IR pass-through for remote control from the receiver side and PoC (Power over Cable) so the transmitter can supply power to the receiver via Cat 6, removing the need for an extra power adapter.
Advantages
The VE1821 provides low-latency 4K transmission with support for high-quality, lossless audio formats and an EDID management system to match source and display capabilities. Its palm-sized, lightweight enclosures simplify installation in constrained spaces and the local HDMI output enables signal monitoring or cascading. IR pass-through and PoC reduce cable clutter and allow remote control and simplified power management.
Suitable for
Conference rooms and meeting facilities
Retail digital signage and displays
Home and commercial entertainment systems
Classroom and lecture hall AV setups

How to use
Connect the HDMI source to the transmitter and run a Cat 6 cable from the transmitter to the receiver (up to 40 m). If required, connect the transmitter's local HDMI output to a nearby display for monitoring or cascading. Use the EDID switch or EDID Copying Mode to select the preferred EDID so the source outputs the optimal resolution for the display. Enable IR pass-through by connecting IR emitters/receivers as instructed to control the source from the receiver side. If using PoC, power the transmitter as specified and the receiver will be powered through the Cat 6 cable, avoiding the need for a separate power adapter at the receiver end.
Usage recommendations
For reliable 4K (4:4:4) performance and maximum distance, use a high-quality Cat 6 cable (ATEN recommends 2L-2910) and confirm display compatibility when using EDID Copying Mode. Place the palm-sized units in ventilated, accessible locations to allow IR signal passage and occasional access to the EDID switch.
