The CN9850 KVM over IP Switch allows for remote access to video, audio, and virtual media of a PC or workstation, and features HDMI high-definition video with resolutions of up to 4K DCI (4096 x 2160) @ 30 Hz at both the local and remote consoles. Built with an advanced FPGA graphics processor, the CN9850 offers better image and video quality to enhance the user experience, while also meeting the RS-232 standards for serial control.

For user-friendly operation, a mini USB port on the front panel is designed as a Laptop USB Console (LUC) port for connection to a laptop, which allows the user to access the PC / server for easy routine maintenance without requiring an additional monitor, keyboard, and mouse.

To seamless stable connectivity, the CN9850 is equipped with dual LAN and dual power functionality to keep operations in the server room smooth and efficient. Its power status detection function automatically sends out event notifications when the devices are offline (e.g. power failure) for device status monitoring. Moreover, the CN9850 features a 5-pin Relay / DI (digital input) terminal block allowing for remote reboot of the local server, and receiving digital input from a connected input/alarm device for notification of critical events.

For ease of remote management, the CN9850 WebClient Viewer supports remote desktop access without additional software applications. The HDMI 4K KVM over IP Switch provides a webbased GUI for remote access and management. In addition, a unified multi-language interface can minimize user training time and increase productivity.

The CN9850 is ideal for data centers, server rooms, and control rooms for remote access management in industries with requirements for high-quality images and multitasking, such as global organizations and companies with several office locations where it can function as a bridge between local and remote workplaces.
