●It has 2 RS-232 communication interfaces
●Support seamless screen switching, seamless products support partition splicing
● With built-in GUI interface, multi-user management, custom device name

●Plug-in card structure: input signal Video, VGA, YPbPr, DVI, HDMI, HD-SDI, optical fiber, network, output signal support: HDMI, card structure DVI (color difference VGA), Video, optical fiber, network, card mechanism, extremely easy to expand or replace.

●Long-line drive capability: the input has automatic equalization to effectively reduce the deterministic jitter (ISI) caused by line transmission, the output has a pre-emphasis function so that the receiver can still receive the signal after long-line transmission, and the input supports reception delay to effectively compensate for the time when the differential pair line is unequal in length.

● HDCP Compatible: Make sure that the media with content protection can be displayed normally, such as Blu-ray DVD, GAME BOX, etc.

●Audio access function: VIDEO, VGA, and chromatic aberration input board have audio input interface, and with the audio separation output function of the output board, audio and video synchronization can be switched without the need for additional audio switching equipment.

●EDID support calculation function: It can automatically calculate the intersection and collection of EDID information of any output display in real time. When an input signal is sent to multiple display devices with different resolutions, it can automatically obtain the best resolution of the current switching state and trigger the signal source to change the resolution (automatic mode).

●EDID supports switching function: the EDID information of any output display device can be read back and switched to any other output display device (manual mode).

● Control interface: with 2 channels RS232 support control and cascading third-party devices. Network interface TCP/WEB cloud control or infrared remote control can be selected.

●Power-down memory function and on-site memory function: with power-off on-site protection function, and can save and recall 10 switching states.

●Input and output: up to 16 signal inputs, 16 signal outputs. Supports cross-switching of embedded multi-channel digital audio signals.

●Input and output cards: Each board has 2 channels, and can be configured with input cards of different formats (Video, VGA, YPbPr, DVI, HDMI, HD-SDI, optical fiber, network) according to requirements.

● Support Full HD: Compatible with all HDTV resolutions including 1080p/60 and up to 1920*1200 PC resolution;

● With built-in GUI interface, multi-user management, custom device name

●Supports 3D, HDMI 1.4, HDCP, and DVI 1.0 protocols. Supports high color depth and up to 3.25Gbps rate;

●All output channels can support seamless screen switching (optional), the interface signal is fully compatible, and the adaptive output parameters (resolution, up, down, left and right size) are independently adjustable, and after the function is expanded, a resolution can be selected as the resolution of the output, so as to solve the small differences such as 1360*768 and 1366*768, and the phenomenon of inaccurate border alignment in other cases.
