Where is the IR interface on the computer? Introduction to the infrared interface of the computer

Desktops are generally not equipped with infrared devices, to buy an infrared adapter, notebook you just need to check yourself, to see if there is a dark red plastic port about one centimeter long and half a centimeter wide around the notebook, if there is a built-in infrared device, then enable it.

There will be two situations, one is that it has been enabled in BOIS, as long as it is set in the control panel, the control panel - wireless connection - infrared device - enable the device. The second way is to go to the System Settings (BIOS) and press + to switch to the page with the Infrared Data Port option, press the < > button to select the Infrared Data Port, select the COM port you want to use, enable the Infrared Data Port, after enabled, the Infrared Mode sub-option will appear, and then proceed to the first step.

Next, turn on the infrared acceptance of the mobile phone, generally in the settings options, and then align the mobile phone with the two infrared ports of the computer, and the computer will automatically pop up to find another computer that is remote, and you can upload or **.

1. Take a mobile phone with infrared function close to your computer, and if the computer tells you to find new hardware, you can know that there is an infrared interface, 2. Look for the manual to see if the motherboard has this function.

Is it only a notebook?

Infrared communication is a cheap, short-range, non-wired, low-power and confidentially strong messy communication scheme, which is mainly used in wireless data transmission in PCs, but has gradually begun to be used in wireless network access and short-range remote control of household appliances. Due to the many benefits of infrared communication, almost all motherboards today provide an infrared interface, so that users can use it to communicate with devices with infrared interfaces, such as laptops, printers, modems, PDAs, mobile **, etc. However, the motherboard of the computer only provides an infrared interface, but does not provide a complete transmitting and receiving device, so users still need to purchase an infrared connector when they want to use infrared communication.

1. Check the manual of the computer motherboard, find out the description of the infrared interface, and determine the approximate position of the five-pin infrared port on the motherboard.

2. Turn off the computer, open the computer case, and look for the infrared interface. The standard IR interface is a single-row five-pin and has the IR logo printed on the board, as shown in the image on the right, so it is not difficult to find.

3. Distinguish the polarity and insert the five-wire insert on the five-pin infrared port. The definition of the infrared interface pin of the motherboard is shown in the figure below, note that the second pin is useless, and the second hole of the five-wire insert does not have a lead, you just need to put the two empty pins together, and you will not plug in the wrong direction.

For the motherboard IR port with special pin definition, the insert pins may need to be adjusted, and the following is the function definition of each line of the five-wire insert:

Red wire: VCC power supply.

Empty and green line: IRRX IR reception.

White line: GND grounded.

Yellow line: IRTX IR emissions.
