ATEN VE1812

HDMI HDBaseT Extender with PoH (4K@100m) (HDBaseT Class A)

The ATEN VE1812 is a high-performance HDMI HDBaseT extender kit engineered to simplify long-distance audiovisual deployments. Designed to transmit high-definition video, embedded audio, and control signals over a single Cat 5e/6/6a cable, it supports full HDMI with HDCP and EDID management. Packaged as two compact, rack-mountable modules—a transmitter (VE1812T) and receiver (VE1812R)—this solution supports up to 4K video at extended cable lengths and includes bi-directional RS‑232 and IR control channels, as well as built-in Power over HDBaseT (PoH), eliminating the need for a separate power supply at the remote display unit.

In standard mode, the VE1812 delivers 4K resolutions (4096×2160 or 3840×2160) at up to 60 Hz with 4:2:0 chroma subsampling or 30 Hz with 4:4:4 over Cat 6a (or ATEN’s recommended Cat 6 cable) up to 100 m. When extended reach isn’t needed for 4K, enabling Long Reach Mode allows 1080p signals to travel up to 150 m over Cat 5e/6/6a cables. This feature combination makes the VE1812 ideal for installations like digital classrooms, high-end meeting rooms, or stadium multimedia systems that demand reliability and flexibility across lengthy runs.

Signal integrity is maintained via HDBaseT Anti‑jamming technology, ensuring consistent video and audio delivery even in electrically noisy environments. The system supports deep color, 3D content, CEC commands, and full HDCP 2.2 encryption compliance. An EDID Expert mechanism dynamically negotiates optimal display resolutions and refresh settings, helping to avoid blank screens or resolution mismatches during setup .

Control features further enhance usability: the VE1812 extends bi-directional IR and RS‑232 signals, allowing source devices to be controlled from the display end and display devices to be managed from the source unit. This two-way infrared channel supports frequencies from 30 kHz to 60 kHz and is processed one direction at a time, accommodating a wide range of remote-control scenarios. The serial channel supports up to 19200 baud and standard 8‑bit, no-parity formats, enabling integration with touch panels, barcode scanners, or external control systems .

Physically, both transmitter and receiver are enclosed in sturdily constructed metal housings, around 13.6 × 10.1 × 2.9 cm and weighing approximately 0.47 kg. Each unit includes slide switches for enabling Long Reach Mode and handling firmware updates. The VE1812T unit consumes approximately 6.4 W and the VE1812R around 4.3 W at 5 V DC input with locking power jacks for secure connection. Status LEDs indicate power, link integrity, and HDMI output status on the receiver, simplifying diagnostics during installation or troubleshooting .

Environmentally, both units operate reliably in typical indoor conditions (0–40 °C) with tolerance to up to 80% relative humidity (non-condensing) and can be stored down to –20 °C or up to 60 °C without damage. The EMI-shielded metal chassis and ESD protection make the product durable in public or industrial AV installations .

Installation is straightforward: connect the HDMI source to VE1812T and display to VE1812R, link both units via RJ‑45 Cat 5e/6/6a cable, and power either side (or rely on PoH from the transmitter to the receiver). Optional use of Long Reach Mode and EDID switch settings enables fine-tuning of range or compatibility. Final tuning of video quality and control settings can be performed with dip switch settings without complex configuration .

In real-world deployment scenarios, VE1812 enables centralized AV sources—such as media servers or video processors—to serve remote displays with pixel-perfect video to classrooms, showrooms, control centers, or signage installations. Power over HDBaseT significantly reduces cabling complexity by powering the receiver unit remotely, and the IR/serial pass-through enables intuitive control integration without separate networks or control hubs.

In summary, the ATEN VE1812 HDBaseT Extender with PoH delivers high-resolution video, audio, and control over extended distances with minimal infrastructure. Its support for up to 4K video at substantial distances, plus advanced features like Long Reach mode, PoH, RS‑232/IR pass-through, HDCP compliance, and configurable EDID, make it a versatile and robust solution for professional AV deployments requiring long cable runs without compromising performance.
