Colorlight S6F HD LED Sender Box
The Colorlight S6F is an LED display sending box for synchronous video systems. It accepts HDMI or DVI video, provides matching loop outputs, and sends the mapped image to compatible Colorlight receiving cards through six Gigabit Ethernet outputs or three optical fiber outputs. Its maximum LED load is 2.3 million pixels; the maximum width is 4096 pixels and the maximum height is 2560 pixels. These are separate limits, not a 4096 × 2560 pixel canvas.
Key features
- HDMI and DVI input with loop: connect a video source and pass the corresponding signal onward to another device.
- Six Gigabit Ethernet outputs: map and splice LED screen areas across the output ports.
- Three fiber outputs: use optional single-mode, twin-core SFP modules with Dual-LC connections for longer links; Colorlight specifies up to 2 km with the optional module.
- Setup and control: dual USB 2.0 interfaces support configuration and cascading; a LAN port supports Fast Ethernet control.
- Display adjustment: brightness and color-temperature adjustment, improved grayscale at low brightness, and HDCP support.

Planning an S6F LED display system
Connect the HDMI or DVI source to the S6F, assign the screen area to its Ethernet or fiber outputs, and connect those outputs to compatible Colorlight receiving cards. Check the total pixel count as well as the width and height limits before selecting the controller. Fiber modules are optional, so confirm the installed SFP modules and receiving-side fiber equipment for the planned link.
Frequently asked questions
How many Ethernet ports does the Colorlight S6F have?
The S6F specification lists six Gigabit Ethernet output ports. Its three optical fiber outputs provide a separate transmission option.
Does 1920 × 1200 describe the LED wall capacity?
No. 1920 × 1200 at 60 Hz is the maximum video input resolution. The LED output load is up to 2.3 million pixels, with independent width and height limits of 4096 and 2560 pixels.
Are the fiber modules included?
The manufacturer identifies the single-mode SFP modules as optional. Confirm the supplied configuration before ordering or installing a fiber link.
