Kystar KS604 LED Sending Box Overview
The Kystar KS604 is a sending-card management box for LED screen walls. It brings card mounting, power management and DVI signal distribution into one chassis, helping installers organize a system that uses multiple LED sending cards.
Its two independent DVI splitters each duplicate one input to two outputs. The KS604 provides the enclosure and signal distribution; the installed sending cards determine the LED output connections, receiving-card compatibility and screen loading capacity.
Key Features
- Four-card installation: space and independent power supply for four small sending cards.
- Dual DVI distribution: two separate 1-to-2 splitters provide four DVI-D outputs from two DVI inputs.
- 1.5U chassis: suitable for organizing the sending-card section of a rack-based LED wall control system.
- Documented signal modes: the specification lists 1920 × 1080, 1920 × 1200 and 2560 × 1024 at 60 Hz, among other DVI timings.

Supported DVI Signal Timings
The linked KS604 specification lists the following input and output timings at 60 Hz: 2560 × 1024, 1536 × 1536, 2048 × 1152, 1920 × 1200, 1920 × 1080, 1680 × 1050, 1600 × 1200, 1440 × 900, 1400 × 1050, 1366 × 768, 1360 × 768, 1280 × 1024, 1280 × 800 and 1024 × 768. It also lists custom timings within the 2560 × 1024 at 60 Hz range.
Resolution clarification: the document’s approximately 2.6-million-pixel copying specification describes DVI signal duplication. It is not a guaranteed total LED wall loading capacity. Verify the source timing, installed sending cards and receiving system together.
Environmental specification note: the available document has inconsistent temperature and humidity units. Confirm the allowable operating temperature and relative humidity for the supplied unit before installation.
Choosing a Sending Box for Your LED Wall
Use the KS604 when your system calls for several sending cards in one enclosure and duplicated DVI feeds. Before ordering, prepare the LED wall’s pixel width and height, the source device’s output timing, and the exact sending- and receiving-card models.
- Check the supplied configuration. Confirm whether the quotation includes sending cards, their exact models and the required internal wiring.
- Match the source signal. Check the chosen DVI timing against both the KS604 specification and the sending-card requirements.
- Check the complete LED control chain. Confirm card capacity, receiving-card compatibility and cabinet mapping before calculating the required number of cards.
- Plan the rack space. Allow room for the chassis, cable connections and the ventilation required by the installed equipment.

Frequently Asked Questions
How many sending cards can the KS604 accommodate?
The specification provides for installation and independent power of four small sending cards. Mechanical fit and electrical compatibility must be checked for the selected card model.
Are sending cards included with the KS604?
The four-card installation capacity does not establish the package contents. Confirm the card quantity and exact models included in your quotation before purchase.
Are its four DVI-D outputs four Ethernet LED outputs?
No. The four outputs listed for the built-in splitters are DVI-D signal connections. LED data output ports and their loading limits depend on the sending cards fitted to the box.
Does the KS604 replace an LED video processor?
The documented functions are card management and DVI duplication. Do not assume video scaling, source switching or multi-window processing; specify those functions separately if your installation needs them.
