Description

Multi-Channel Wireless Input Device

technical field

The invention relates to a multi-channel wireless input device.

Background technique

It is known that the traditional computer and each interface device must pass through an appropriate transmission interface, and they need to be connected to each other with signal cables for signal conversion and data transmission: Recently, wireless signal transmitters and receivers have been further used. Receive control signals transmitted by various wireless interface devices, such as through a universal serial bus (USB) signal transmitter, so as to realize the purpose of making each USB interface device control and operate the computer in a wireless (WIRELESS) manner.

Most of the signal transmitting modules and signal receiving modules of wireless interface devices and computer systems use radio frequency (RF) modules for transmitting and receiving signals, and because more and more interface devices are designed to be wireless structures, if the channel allocation Inappropriate, it is easy to cause interference, and, because the wireless interface device needs to be fixed for a period of time to repeatedly send identification signals between the wireless interface device and the host computer, the host computer cannot send signals to multiple wireless interface devices at the same time. Simultaneous reception and identification may easily cause errors in the actions of the transmitter module, and even affect the normal operation of the remote wake-up function.
