ˇ FCC NOTE: This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:(1)this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate ra dio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio comm unications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: -- Reorient or relocate the receiving antenna -- Increase the separation between the equipment and receiver. -- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -- Consult the dealer or an experien ced radio/TV technician for help. The manufacturer is not responsible for any radio or TV interference caused by unauthorized modifications to this equipment. Such modifications could void the user's authority to operate the equipment.

Circuit description Desktop KVM SWITCH KVM switch can be a good solution to the 2 to 4 single server or PC for day to day management and maintenance. It is the server, PC mouse, keyboard, VGA signal input through the input port, control port connection control personnel, mouse, keyboard, monitor. VGA signal and the mouse and keyboard signals through the selector, according to the requirements of controllers, controllers sent commands to the microcontroller and microcontroller after receipt of order to give the choice of chip for each port to send commands to make the selection switch to a single user's needs PC or server to operate! 1, input VGA signal through the resistor after the matched-impedance input to the selector chip, and then select the device directly from the MCU control, the operator sends commands to the microcontroller and microcomputer control VGA signal selector select a group of users need to VGA signal, the user selector need to VGA signal to the integrated op-amp chip signal amplification transmission to the control side of the display, in order to achieve choice! 2, the input signal directly to the mouse and keyboard signals into the microcontroller, microcontroller according to the user's requirements need to control the choice of server or PC, microcontroller also sends instructions to ensure the mouse, keyboard, and VGA signal synchronization work! control the oscillation frequency of the external MCU 20MHz.
