The output card is a hardware device that outputs the signal source from the KVM agent processor. The input card is a hardware device that inputs a signal source to the KVM agent processor. In this embodiment, there are two seats. The seat is an operation seat and is responsible for displaying the seat content. The RX device is used for converting optical signals into electric signals and outputting the electric signals to seat displays, and the KVM seat processor is used for transmitting and processing various converted signals.
The electrical signal source outputs an electrical signal which is transmitted to the TX device, and the TX device converts the electrical signal into an optical signal and outputs the optical signal to the KVM seat processor.
