Embodiment Construction
[0021] figure 1 It is a pin layout diagram showing the interface circuit of the infrared transmission module in the prior art.
[0022] Such as figure 1 As shown, the interface circuit used to connect to the infrared transmission module on the computer motherboard includes 5 pins 1-5. The arrangement of these pins of the interface circuit is well known in the art, so it will not be described in detail. It should be noted that pin 1 is connected to the power supply voltage Vcc (ie, high level), which can be referred to as a power supply pin here. Under normal circumstances, when the host with the infrared transmission module is assembled, the independent infrared transmission small board with the infrared transceiver in the infrared transmission module is plugged into the upper 5 PIN pins.
[0023] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
