StarTech ST121R VGA Receiver
Overview
The StarTech ST121R is a VGA receiver unit designed to extend and distribute a VGA video signal up to 150 meters (492 feet) over a single Cat5 or Cat5e Ethernet cable. This unit is intended for use with a compatible ST121T transmitter (sold separately) to create a point-to-point or point-to-multipoint VGA distribution system. It's ideal for digital signage, security monitoring, or presentation environments where a VGA source needs to be displayed on multiple screens at a distance, such as in large offices, retail spaces, or lecture halls.
Compatibility
This receiver unit is compatible with the StarTech ST121T VGA transmitter. It supports various resolutions depending on the cable length: 1600x1200 at up to 150 feet (45m), 1280x1024 at up to 300 feet (91m), and 1024x768 at up to 500 feet (152m). It requires standard Cat5 or Cat5e cabling for signal transmission.
Installation Notes
The ST121R requires a 12V DC, 0.5A power adapter (included) to operate, consuming a maximum of 6 Watts. It features two VGA output connectors to connect to displays and one RJ-45 connector for the Cat5 cable input. Ensure the Cat5 cable run is within the specified length for the desired resolution to maintain signal integrity.
