Colorlight S2 is an external LED sending box for a synchronous LED display system. It takes a DVI signal from a video source and sends display data to compatible Colorlight receiving cards through two Gigabit Ethernet ports. Its total loading capacity is up to 1.31 million pixels.
Colorlight S2 sending box at a glance
- Video input: DVI, up to 1920 × 1200 pixels at 60 Hz; frame rate can adjust automatically.
- LED outputs: two Gigabit Ethernet ports, each rated for a 1280 × 512 pixel control area or equivalent.
- Total load: up to 1280 × 1024 pixels or equivalent, approximately 1.31 million pixels. A 2560 pixel maximum applies to either width or height, subject to the total pixel budget.
- Setup and expansion: dual USB 2.0 interfaces enable PC configuration and cascading of sending units.
- Other functions: audio transmission, brightness and color temperature adjustment, DVI input detection, and Ethernet cable error detection.
How the S2 fits into an LED display system
Connect the DVI output of a computer or video source to the S2. Connect its Ethernet outputs to the receiving cards in the LED cabinets, then configure the screen mapping through Colorlight software. The two outputs can be arranged for vertical or horizontal screen splicing. For cable planning, Colorlight’s S2 controller specification recommends CAT5e runs of no more than 100 m; verify the complete installation and receiving-card configuration before deployment.
