Chapter 1 Introduction

Overview

Featuring powerful Class A HDBaseT technology, the VE2812R / VE2812PR is a receiver for 4K HDMI video, audio, and control signals over a distance of up to 100 m via a Cat 5c / 6 / 6a or ATEN 2L-2910 Cat 6 cable. HDMI signal transmission extends further up to 150 m @ 1080p when the HDBaseT Long Reach Mode is enabled.

Designed to optimize flexibility, the VE2812PR ships with 2-way PoH capability, either allowing a PoH PD-enabled Tx (VE2812AT series is recommended) to be remotely powered by the locally powered VE2812PR, or enabling power distribution along the cable from a PoH PSE-enabled Tx (VE1812T is recommended) to the VE2812PR.

Speaking of VE2812R / VE2812PR's audio dc-embedding, audio signal can be extracted from the incoming HDMI source and then transmitted through Coaxial or Stereo output to external audio distribution systems. The VE2812R / VE2812PR gives users the extra convenience when it comes to extending control and communication signals via the built-in RS-232 and bi-directional IR ports. Plus, it is HDCP 2.2 compliant and supports HDMI specification features, such as 4K2K, 3D, Deep Color, and CEC for reliable transmission of high-quality uncompressed HDMI content.

With all highlights packed in a compact enclosure, the VE2812R / VE2812PR assures easy and discreet installation, keeping the presentation space tidy. It is ideal for small / mid-sized areas where 4K HDMI and control signal transmission over a long distance is required, such as boardrooms, lecture halls, and digital signage applications.

Features

• Transmits 4K HDMI up to 100 m / 330 ft via Cat 5c / 6 / 6a or ATEN 2L-2910 Cat 6 cable
- Transmits HDMI up to 150 m / 492 ft @ 1080p in HDBaseT Long Reach Mode
• Bi-direction PoH*:
- Allows a PoH PD-enabled Tx to be remotely powered by the locally powered VE2812PR
- Enables power distribution from a PoH PSE-enabled Tx to the VE2812PR over the cable
- Audio de-embedding — extracts audio stream from the HDMI source and delivers as a separate audio from HDMI to Coaxial S/PDIF, or Stereo audio output
• Supports Audio EDID Switching (2ch Stereo, 5.1ch Surround sound, and AUTO)
- RS-232 serial communication switch — switch between command mode and bypass mode for various application requirements
• Supports bi-directional IR signal transmission (IR transmission is processed one direction at a time)
• HDMI (3D, Deep Color, 4K); HDCP 2.2 compliant
- Firmware upgradable
• Built-in 8KV / 15KV ESD protection
- Plug-and-play
• Rack-mountable using the VE-RMK1U

Note: The bi-directional PoH capability is only supported on VE2812PR.

Planning the Installation

Requirements

Prepare the following before installing the VE2812R / VE2812PR unit:

• 1 HDMI display device
  ♦ 1 Cat 5c/6/6a or ATEN 2L-2910 Cat 6 cable

Considerations

• To ensure video quality, use a Cat 5e/6/6a cable.

Note: For best results, ATEN recommends using the ATEN 2L-2910 Cat 6 cable.

- The maximum transmission distance varies at different parts of the transmission:

Connection Interface Max. Distance
The VE2812R / VE2812PR to a compatible ATEN Video Extender Transmitter	Cat 5e/6/6a 100 m / 150 m(up to 1080p in Long Reach Mode)
The VE2812R / VE2812PR to a display	HDMI 3 m

Compatible Products

The VE2812R / VE2812PR is designed to work with VE2812AT / VE2812AUST / VE2812AEUT / VE3912T, and also compatible with a wide range of ATEN video splitters, video switches, video extender transmitters, and video converters. Visit our official web site for more details.

To enable long reach mode, put the HDBaseT long reach mode switch to ON at either the transmitter or the connected receiver.

Note: When long reach mode is enabled, the VE2812R / VE2812PR will not be able to transmit 4K signals, in which case, the output display will be blank.
