Installation and setup of Motherboard infrared interface

first, the advantages of infrared interface

The biggest advantage of infrared port communication is convenience, use their own special connection protocol, data transmission speed can reach 4Mbps, and in the effective area, you can realize the dynamic addition of multiple machines, dynamic exit connection, so that multiple users dynamically establish or terminate the connection, realize the "breakpoint continued transmission", has a better security function. Now most of the new motherboards are provided with infrared interface, we want to use it must also have a dedicated infrared connector, the connector can buy ready-made products or homemade. Of course, if you're using a laptop with an infrared function, that's more convenient.

　　Installation and setup of infrared interface of motherboard

First to install the infrared connector, connect the Infrared interface connector and the motherboard infrared interface should pay attention to the direction of the 5-pin socket, side to ask the reverse may cause the motherboard interface damage.

1, correctly set the motherboard BIOS

Use the motherboard IR interface with the "onboard IrDa Port" or related option set to enable in the BIOS "Integrated peripherals" submenu, and the "UART2 use infrared" item to IrDa. Typically, the COM2 of the motherboard is set to the infrared transport interface. The motherboard COM2 interface will therefore be out of effect.

In the infrared transmission mode "UART mode Select", If selected "Hpsir", can only pass the standard speed 115.2Kbps transmission data, select "Askir" can enjoy the highest speed of infrared 4Mbps. "Hpsir" is recommended when not connected by 4Mbps.

2, System software and protocol installation settings

After the installation is successful, double click on "My Computer" and you will find an extra "infrared receiver" icon. After you enter the control panel, you can modify its status with the new "infrared" option. Then you will find that you have an "infrared port" and a "Fast Infrared Protocol" installed in the network. All of these indicate that your infrared transceiver is properly installed.

3, the use of infrared port to achieve dual-computer interconnection

The most common function of the motherboard infrared port is to realize the dual-computer interconnection.

　Third, the application of the infrared interface of the motherboard

1, for infrared transmission

(1) In "Control Panel/System", open "infrared Monitor", in the "Options" tab, the "Start infrared communication" check box point, and then click "Apply", the infrared receiver can work.

(2) In the Device list box in the Control Panel/System/Device Management tab, add entries such as virtual infrared parallel (LPT) ports, virtual infrared serial (COM) ports, infrared communication devices, and Infraredpnpserialport (Plug and Play infrared serial ports).

(3) Open the list of Control Panel/Network/Configuration tab, add "Infraredpnp SerialPort" and "Fast Infrared transport Protocol", and bind "Fast Infrared transport Protocol".
