Adder ALAV100T-US – AdderLink AV100 VGA Signage Transmitter

Product Overview

The Adder ALAV100T-US is the transmitter unit of the AdderLink AV100 series, a VGA and stereo audio extender over CATx developed for digital signage distribution. This VGA digital signage transmitter sends high-resolution analog video together with digital stereo audio across a single CATx cable to remote AV100-series receivers, supporting long-distance runs of up to 300 meters. It allows media players and signage PCs to remain in a secure equipment room while displays are positioned where audiences see them. The US suffix denotes the version supplied with a United States mains lead.

Product status: The AdderLink AV100 series is a legacy Adder AV product line that is no longer part of Adder's current extender catalog. It remains relevant for maintaining and expanding existing VGA-based signage and AV installations, and Adder continues to host the official series documentation.

Product Description

VGA remains embedded in countless installed signage networks, point-of-sale displays, and corporate AV systems, and the AV100 series was Adder's dedicated platform for extending those signals economically over structured cabling. The ALAV100T-US transmitter connects to the source computer's VGA output and audio output, then drives the link to a remote receiver over a single CATx cable.

According to Adder's AV100 series documentation, the system delivers video resolutions up to 1600 x 1200 at shorter distances, with extension possible to a maximum of 300 meters over CATx cable as resolution requirements allow. Audio travels alongside the video as digitized stereo sound sampled at 44.1kHz, avoiding the noise pickup associated with running analog audio over long copper distances.

The transmitter includes a local feed-through video connection, so an on-site monitor can be retained at the source for setup and monitoring while the extended display runs simultaneously. As an analog VGA extender over CATx, the unit operates without drivers or host software, making it independent of the operating system on the connected media player.

For new HDMI-based signage extension projects, consider the current-generation AdderLink DV100 HDMI transmitter (ALDV100T). Replacement receivers, cabling, and the rest of the range are available in the Adder Technology collection at Creation Networks.

Key Features

• Long-Distance VGA Extension — Extends VGA video over a single CATx cable to remote AV100-series receivers at distances up to 300 meters.
• High Video Resolution — Supports resolutions up to 1600 x 1200, with the achievable resolution dependent on cable run length.
• Digitized Stereo Audio — Carries 44.1kHz sampled stereo audio together with video on the same CATx link for clean long-run sound.
• Local Feed-Through Output — A local video connection allows a monitor at the source location for configuration and confirmation of output.
• OS-Independent Operation — Works without drivers or software, so any VGA-equipped media player or PC can act as the source.
• Legacy System Support — A practical match for maintaining installed VGA signage networks built on the AdderLink AV100 platform.
