The DA1921SX is designed for use together with an ALTINEX CAT-5 UTP Computer Video Transmitter, such as model # DA1920SX. The DA1921SX receives computer video signals over twisted pair CAT-5 UTP (Category 5, 5e) type cable and converts the signal format to a standard VGA-type (VGA to UXGA) output for use with a large screen projectors or other displays.
This is an alternative to the traditional method of using RGB or VGA type multi-channel coaxial cable, a solution that is desirable due to the fact that CAT-5 cable is thinner, more flexible and less costly than multi-channel coaxial cable. Also, many facilities already have a CAT-5 cable infrastructure, allowing this solution to reduce the amount of labor and intrusion required for retrofit installations.
The DA1921SX is compact and easy to use. It offers a female RJ-45 input connector and two female 15-pin HD output connectors. Both outputs are fully buffered, in effect providing a built-in 1-In 2-Out distribution amplifier.
The DA1921SX can receive signal resolutions between VGA and UXGA. Used 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.
All cables for the DA1921SX must be ordered separately
