KYStar KS604 sending-card box
The KYStar KS604 houses up to four small LED sending cards and includes two independent one-to-two DVI splitters. The 1.5U enclosure combines card installation, power distribution and video-signal routing for an LED control system.
Signal distribution and card installation
The two splitter groups provide two DVI inputs and four DVI-D outputs. Each group copies one source to two outputs. The manual describes video-processor output feeding the box, followed by DVI connections to the installed sending cards.
Actual Ethernet connections and LED pixel load depend on the fitted sending cards. Confirm physical fit, supply connections and the supplied card quantity; the enclosure capacity does not establish that four cards are included.

Source notes: The manual’s machine table lists 100–240 V AC, but its safety section says 100–220 V AC. Verify the supplied unit’s nameplate before connection. The “Working humidity” row is printed as 0–40°C, so no valid humidity range can be confirmed from that row.
Frequently asked questions
What is the difference between KS604 and KS606?
The KS604 documentation specifies space for four sending cards plus two independent 1-to-2 DVI splitters. The KS606 page describes installation space for six small sending cards. Check the required card and signal-routing configuration.
Does KS604 create four independent video images?
Its two built-in DVI splitters duplicate their respective inputs to two outputs each. Independent content and final LED layout depend on the sources and sending-card configuration.
Are the four sending cards included?
The manual confirms installation capacity for four small cards, not a universal included-card quantity. Confirm the supplied card models and quantity for the order.
What should I check before connecting power?
Check the actual unit nameplate and supplied revision. The manual contains 100–240 V and 100–220 V AC statements in different sections, so those ranges should not be treated as interchangeable.
