Colorlight S2 LED display sending card
The Colorlight S2 sending card accepts a DVI video source and provides two Gigabit Ethernet outputs for an LED display of up to 1.31 million pixels. The maximum input resolution is 1920×1200 pixels. This is the card-format S2, with USB configuration and a PCI-E 1X interface for power.
Power connections and hardware revision
The linked V3.2 specification separates the power inputs: the VH2.54 mm 4-pin connector accepts DC 3.8–5.5 V, while PCI-E 1X uses DC 12 V. The earlier page combined these into a DC 3.8–12 V range; that combined range must not be applied to the 4-pin connector. The V3.2 board dimensions are 135.16×101.93 mm, differing from the earlier listing’s 140×105 mm.

Replacement and transmission planning
For an IT7 replacement or other existing Colorlight system, check the power connector, mounting, receiving cards and configuration files before choosing the S2. The linked specification does not establish unconditional drop-in replacement compatibility.
V3.2 lists CAT5e up to 140 m and CAT6 up to 170 m; verify the proposed installation and cable before relying on those figures. Fiber transmission uses external transceivers, and a suitable module and link budget must be selected rather than treating the distance as unlimited.
Frequently asked questions
What voltage should power the S2 sending card?
V3.2 specifies DC 3.8–5.5 V at the VH2.54 mm 4-pin connector and DC 12 V through PCI-E 1X. These are different power connections; do not apply 12 V to the 4-pin input.
Does the PCI-E interface carry the S2 video input?
The hardware table identifies PCI-E 1X as a power connection. DVI is the video input, and USB Type-B is used for PC configuration.
Can the S2 card directly replace a Colorlight IT7?
Verify power, mounting, receiving-card compatibility and configuration before replacement. The linked S2 specification does not confirm that every IT7 installation is a drop-in match.
Is audio input standard on the S2 sending card?
The V3.2 specification identifies audio input and transmission as optional and references use with a multifunction card. Confirm the supplied configuration if audio is required.
How many pixels and outputs does the S2 card support?
It supports up to 1.31 million pixels through two Gigabit Ethernet outputs. Each port is listed for 1280×512 pixels or an equivalent area, within the total loading limit.
