ABOUT YOUR DA1921SX 2

The DA1921SX is a high-resolution 1-in 2-out computer video amplifier/receiver. It converts differential signals from a CAT-5 transmitter to single ended video signals. These single ended signals allow the source to be distributed to large screen projectors or other displays with excellent quality at long distances. The DA1921SX is designed to be used together with a compatible CAT-5 computer video transmitter, such as model DA1920SX. The DA1921SX is connected to the transmitter using twisted pair CAT-5 UTP (Category 5, 5e, 6) type cable.

The DA1921SX is compact and easy to use. It offers a CAT-5 input, two fully buffered outputs and equalization control. It is perfect for audio/visual installations, where a single computer sends signals using inexpensive, thin, light CAT-5 cable.

The DA1921SX can receive signal resolutions from VGA thru UXGA. Together with an ALTINEX CAT-5 computer video transmitter and properly adjusted with the built-in equalization controls, the maximum cable distance is approximately 500 feet/152 meters for VGA (640 x 480, 60 Hz refresh rate) and 250 feet/76.2 meters for UXGA (1600 x 1200, 60 Hz refresh rate). Please see the complete specifications for other resolutions.
