Win xp system and infrared new technology intimate contact

Nowadays technology is more and more developed, many people buy peripherals are very advanced, such as mobile phones can use infrared to connect computers, but infrared we rarely touch, then If you want to use infrared to contact the computer, what should you do? Here is the answer for you.

First of all, after we purchase the usb infrared adapter, turn on the computer. The new machine generally does not need to plug in the usb infrared adapter first or boot into the system and then plug in the usb infrared adapter, but some old machines need advanced systems. Plug in the usb infrared adapter, otherwise you will not find the usb infrared adapter.

After we have prepared the usb infrared adapter, turn on the computer. The new machine generally does not need to plug in the usb infrared adapter first or boot into the system and then plug in the usb infrared adapter, but some old machines (p3 level) There are) advanced systems and then plug usb infrared adapter, otherwise we will not find usb infrared adapter, this should be noted.

After plugging in, the system will prompt to find new hardware, and then automatically install the driver. After the installation is complete, the system will say that it can be used.

Here, we can double-click the safely delete hardware icon in the lower right corner of the computer screen, and then we will find a device with "sigmatel usb-irda adapter", click it with the mouse, and then Click below "Properties".

We take the nokia mobile phone as an example. First, you need to click the above "Advanced Menu", in the "Advanced Menu" we can click the "infrared transceiver type" in the first line, and then click The value on the right, you can find three options such as sigmatel 4000, if we start to install the nokia pc kit, the final connection is unstable or even impossible.

One of the reasons is that windows integrates many hardware drivers for plug-and-play, but in fact the hardware update speed is much faster than the operating system, so many of the windows integrated drivers we use are outdated, new Hardware support is also limited.

Another reason is that not every hardware is 100% identical. Most vendors have their own driver developers. Different brands of hardware drivers are different. Usually only manufacturers know. It is best to use your own hardware to drive the program, so we can see that there are more than 100 developers of light drivers in famous factories like Elsa.

Ok, let's get down to business, I said so many people should know that the driver that comes with the usb infrared adapter is a key point? Now let us put the driver of the usb infrared adapter on it. test. First put the driver CD that comes with the usb infrared adapter into the CD-ROM drive.

Or continue with the previous steps, we will open the "Advanced" "Driver" menu on the right, click on "Update Driver" in it, like other hardware drivers The same, you can choose to install the software automatically, but many times the smart windows can not find the driver, very stubborn, then we can specify the installation.

Ok, after installing it, let's look at the value of the right side of the "infrared transceiver type" in the first line of the "Advanced Menu". We will find several options in it. Select "vishay 6101e[defau]".

At this time, we installed the nokia pc kit, then restarted the pc, turned on the infrared connection of the 3650, and pointed to the usb infrared adapter, we found that there is an infrared docking icon in the lower right corner of the screen, and a mrouter Icon, double-click the mrouter icon, select the infrared below. At this time, you can already transfer the file.

But things didn't end here. In the process of file transfer later, we will find that the transmission is unstable and intermittent, especially when transferring slightly larger files, my analysis is 3650. The reason why the memory is too small, the data transmission rate is faster, the large amount of data will cause data jam, and the compatibility of the hardware itself is also a cause.

Let's go back to the "Advanced Menu" we saw earlier. The third line has a "speed enable", the right side has 4000000 (! This is the default for Windows!), 115200 and so on. After many trials, 57600 is the most ideal speed.

Some notes about infrared connection:

1. The speed of the infrared adapter of the mobile phone is only 115200, and now the computer The infrared adapter can be up to 2m. If the speed is not matched, it will easily be disconnected after connecting for 1 or 2 seconds. The infrared speed on the computer can be set in the infrared light in the control panel. On the option page, limit the connection speed to " the front hook and the right side to drop down and select the corresponding speed.

2, in the connection with the synchronization software should pay attention to, in the synchronization software control panel there is a connection settings, which will list com1com2com3 infrared and other options, the notebook comes with infrared as long as you can choose infrared The old notebook infrared is taking up the com2 port, and some are virtual com3com4 ports. You need to try one by one. On my notebook machine (win98), there is also a case where the infrared is invalid and the com3 is valid. Resolve after reinstalling the new version of the software.

3, if it is a desktop external infrared adapter, there are two, one is connected with the computer serial port, if the synchronization software can not connect to the option, you must try to select the corresponding port. Generally choose com1com2, and select the infrared at the same time. If you use the usb interface, unless you are using a virtual port, you do not need to select the com port.
