Colorlight S2 Sending Card

AzarPixel features the Colorlight S2 Sending Card, a compact LED display sending card designed for flexible control of indoor and outdoor LED screen systems. Unlike the S2 controller, this version is a bare sending card without a case. The main difference is that the S2 Sending Card is an internal card-style device without an enclosure, while the S2 controller comes in a case/box and is better suited as a standalone external unit. Functionally, both are used for LED display control, but the sending card is designed for direct integration into a PC or system chassis via PCI-E 1X, whereas the boxed controller is more convenient for external desktop-style deployment and field use. With a DVI signal input supporting resolutions up to 1920 × 1200 pixels at 60Hz, the S2 Sending Card delivers a loading capacity of up to 1.31 million pixels through its two Gigabit Ethernet outputs. It supports screen splicing, multi-screen control, and user-defined cascading in up/down or left/right directions, making it suitable for rental displays, fixed installations, and multi-screen LED applications. This sending card also provides better gray performance at low brightness, brightness and color temperature adjustment, real-time configuration through USB, and Bit error detection for monitoring Ethernet cable quality and potential signal issues.
