Product Overview

The Atlona AT-HDVS-150-TX is a 3x1 HDBaseT switcher and transmitter combining two HDMI inputs and one VGA input with audio, designed to extend signals up to 230 feet (70 meters) over a single category cable. This wall plate HDBaseT switcher for classrooms and conference rooms is part of the HDVS Series, built to work with the AT-HDVS-150-RX receiver and scaler to deliver a complete, automated AV system in a compact form factor. Integrators looking for an HDMI VGA HDBaseT transmitter with automatic input selection and automatic display control will find this unit particularly suited to huddle rooms, corporate boardrooms, and education environments. The AT-HDVS-150-TX is remotely powered via PoE from the AT-HDVS-150-RX, eliminating the need for a local power supply at the transmitter location.

Product Description

The Atlona AT-HDVS-150-TX (SKU: AT-HDVS-150-TX) is a 3x1 AV switcher and HDBaseT transmitter with two HDMI inputs and a VGA input with analog audio. It transmits video signals up to 1080p, plus embedded HDMI audio, up to 230 feet (70 meters) over category cable — making it an efficient choice for any room where the display cannot be placed within standard HDMI cable range of the source equipment.

When paired with the AT-HDVS-150-RX receiver and scaler, the HDVS-150-TX delivers a fully automated AV system. The automatic input selection feature detects active source connections using 5V hot plug detect and switches to the active input without any user intervention. This is particularly valuable in shared-use environments such as classrooms and meeting rooms, where presenters rotate frequently and manual switching is impractical.

The AT-HDVS-150-TX also provides automatic display control when connected to the HDVS-150-RX. Control signals travel to the display via RS-232, enabling the display to power on when a laptop is connected and power off when the presenter disconnects — without a separate control system. A front panel power button also allows manual on/off override for the connected display, giving presenters direct control during sessions.

The transmitter is remotely powered via IEEE 802.3af PoE from the AT-HDVS-150-RX, so no local power outlet is required at the transmitter. Surface mounting brackets are included for under-table, furniture, or on-wall installation. The unit's compact enclosure (1.5 x 5 x 4.02 inches) and simple bracket mount make it straightforward to install in lecterns, conference tables, and collaboration furniture. Firmware is field-updatable via a rear panel USB port to protect long-term system value.

Key Features

• 3x1 Multi-Format Switching — Two HDMI inputs plus one VGA input with analog audio enable connection of both modern digital and legacy analog sources in the same room without format converters.
• HDBaseT Transmission up to 230 ft — Extends AV signals up to 230 feet (70 meters) at 1080p over CAT6a/7, or up to 197 feet (60 meters) over CAT5e/6, using standard category cable infrastructure.
• Remotely Powered via PoE — IEEE 802.3af Powered Device (PD); the AT-HDVS-150-RX receiver supplies power over the HDBaseT cable, eliminating the need for a local outlet at the transmitter.
• Automatic Input Selection — Detects active source connections using 5V hot plug detect and switches automatically, enabling hands-free operation in shared-use rooms.
• Automatic Display Control — When paired with the AT-HDVS-150-RX, controls display power via RS-232 automatically as sources connect and disconnect, reducing energy consumption and simplifying room operation.
• Front Panel Manual Controls — Input selection buttons and a display on/off button allow presenters to override automatic switching and manage the display without a control system.
• Front Panel Status LEDs — Power and input selection indicators provide clear visual feedback for both installers and end users during setup and daily use.
• Field-Updatable Firmware — Rear panel USB port enables firmware updates in the field, extending the operational life of the installation.
• Included Mounting Hardware — Surface mounting brackets are included for under-table, furniture, or wall-surface mounting in a variety of installation environments.
• Compact Form Factor — 1.5 x 5 x 4.02 inch (38 x 127 x 102 mm) chassis fits in confined spaces including lecterns, conference table cutouts, and AV equipment niches.

Typical Applications

• K-12 and higher education classrooms with both laptop (HDMI) and document camera or older PC (VGA) sources
• Corporate boardrooms and executive conference rooms requiring simple, automatic source switching
• Huddle rooms and small meeting spaces where a full control system is not justified
• Government and municipal meeting rooms with mixed HDMI and VGA source equipment
• Lecterns and presenter stations in auditoriums and multi-purpose rooms
• Hospitality and training rooms requiring cost-effective AV automation without a dedicated controller

Frequently Asked Questions

Q: Does the AT-HDVS-150-TX need a local power supply?

No. The AT-HDVS-150-TX is an IEEE 802.3af PoE Powered Device and receives its power over the HDBaseT cable from the AT-HDVS-150-RX receiver. No local AC outlet is required at the transmitter location. An alternative model, the AT-HDVS-150-TX-PSK, includes a local power supply for installations where the transmitter is used with an HDBaseT-equipped projector or a third-party receiver.

Q: How does automatic display control work?

When the AT-HDVS-150-TX is paired with the AT-HDVS-150-RX, the system can send RS-232 commands to the connected display to power it on when a source is detected and power it off when no source is active. This feature requires the AT-HDVS-150-RX and does not require a separate control system or programming.

Q: Can the AT-HDVS-150-TX switch between a laptop (HDMI) and a document camera (VGA) automatically?

Yes. The automatic input selection feature uses 5V hot plug detect to identify the active source and switch to it without user intervention. If both sources are active simultaneously, the front panel input selection buttons allow manual override.

Q: What is the maximum extension distance for 1080p signals?

At 1080p, the AT-HDVS-150-TX extends signals up to 230 feet (70 meters) over CAT6a/7 cable, or up to 197 feet (60 meters) over CAT5e/6 cable.

Q: Is the AT-HDVS-150-TX compatible with 4K displays?

The AT-HDVS-150-TX can pass 4K/UHD signals (3840x2160 or 4096x2160 at 60 Hz, 4:2:0 8-bit) over HDBaseT, but the primary design target is 1080p extension. The AT-HDVS-150-RX includes a scaler; 4K pass-through depends on the receiver's capabilities and the cable category used.

Q: What installation mounting options are available?

The AT-HDVS-150-TX includes surface mounting brackets for under-table, in-furniture, or on-wall installation. Its compact 1.5 x 5 x 4.02 inch form factor fits in lecterns and conference table cutouts.

Q: What is the recommended replacement for the AT-HDVS-150-TX?

Atlona recommends the AT-OME-ST31A for applications requiring 4K/UHD compatibility. The OME-ST31A supports HDMI and USB-C sources, mirrored HDBaseT and HDMI outputs, 4K downscaling, and audio de-embedding.

Q: Where can I purchase the AT-HDVS-150-TX?

The AT-HDVS-150-TX is available at creationnetworks.net, an authorized commercial AV reseller serving integrators and end users across North America.
