SMX USB matrix boards are designed to route up to eight Host CPUs to one or more USB peripheral devices, such as keyboards and mice. They support data transfer rates up to 480 Mbps and are compatible with USB 2.0/1.1/1.0 specifications. Host and Peripheral Emulation is provided on all ports for reliable, problem-free boot up, even without a tie being made to a connected device. Four integrated, two-port USB hubs simplify integration in common keyboard/mouse applications. Each hub port supplies 5 Volts, 500 mA power for attached keyboards, mice, or other peripheral devices. SMX USB Matrix Boards are ideal for use in the creation of KVM - keyboard, video, mouse matrix applications when combined with available SMX DVI, HDMI, or VGA matrix switching boards. They are available in two I/O sizes: 4x4 and 8x4.
