1.31 million with two network ports


S2 supports two network port outputs, and a single card can complete the loading of 1.31 million pixels on the display, with a maximum width of 4000 pixels and a maximum of 2000 pixels.



Stereo audio input


Kystar S2 Sending card supports one stereo audio input, and can be used with the multi-function card MF630 to achieve audio transmission.



Stable hardware


Kystar S2 Sending card not only selects high-quality components, all connectors are high-standard gold-plated parts, and supportive designs such as power protection are added to ensure the true gold quality of the hardware.•Moreover, the S2 has undergone strict high and low temperature and pulse group detection before leaving the factory to ensure that the product is in the most stable state.



Data readback repair


S2 supports data readback and repair functions.•Using the readback configuration function, users can quickly read the correct configuration parameters from the receiving card when replacing the sending card, without having to reconfigure the parameters.

•Using the configuration retransmission function, when the user replaces the receiving card, this function can help retransmit the configuration stored in the device to complete the system repair without reconfiguring the parameters.
