Windows XP Infrared Connection Mobile Process Example Demo

        Many friends bought a new product with infrared equipment, such as a mobile phone, but did not know how to connect the hardware into the computer in infrared mode. We will solve some friends who have just started from the software point of view.

First, after we purchase the usb infrared adapter, turn on the computer. The new machine does not matter whether it is plugged 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 system and then plug 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 matter whether the USB adapter is plugged in first or the system is booted first and then the usb infrared adapter is inserted, 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" inside, click it with the mouse, and then click Below "properties".

Let's take the nokia mobile phone as an example. First, you need to click the "Advanced Menu" above. In the "Advanced Menu", we can click on the "infrared transceiver type" in the first line, and then click on the value on the right. It can be found that there are three options such as sigmatel 4000. If we start to install the nokia pc kit, the final connection in ten or nine 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 manufacturers 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, right? Now let's try to install the driver that comes with the usb infrared adapter. First put the driver CD that comes with the usb infrared adapter into the CD-ROM drive.

Or continue the previous steps, we will open the "Driver" menu on the right side of "Advanced", click "Update Driver" in it, like other hardware drivers, you can choose to install automatically. Software, 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 on the right side of the "infrared transceiver type" in the first line of the "Advanced Menu" we saw earlier. We will find several options in it. We choose "vishay". 6101e[defau]" is fine.

At this time, we installed the nokia pc kit, then restarted the pc, turned on the infrared connection of the 3650, and aligned with 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, the hook of the front of the connection speed is limited to the hook, and the right side can be pulled down to 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 com1\\com2\\com3\\infrared and other options, the notebook comes with infrared as long as Infrared can be selected, the old notebook infrared is taking up the com2 port, and some are virtual com3\\com4 port, need to try one by one, on my notebook machine (win98) also appeared to select infrared invalid, choose com3 Effective situation. 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 connection option, try to select the corresponding port. Generally choose com1\\com2 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.

Due to the variety of external infrared adapters, the drivers are different, and specific analysis is needed. Some people say that the machine does not support the serial port. It should be the reason why com2 is not opened in the biOS of the motherboard. Then there is to see if the serial cable and the motherboard are connected.

4, operating system problems, Windows xp users need to download the 1.20 version of the new synchronization software from the Nokia home page, personal use feels more stable under win2000, 98 is easy to use when setting the port.

5, summed up, if the infrared is installed, if it is different, it must be set up, try different settings on the relevant settings panel, do not damage the computer or mobile phone, Have a practical spirit! The most serious consequence is nothing more than reinstalling the infrared device on the computer.

6. Network Neighborhood -> Properties -> Double click on "sigmatel usb-irda adapter" (other brands may display slightly different information, double click to enter anyway) -> Select Advanced, "infrared" Transceiver" attribute changed to sigmatel 4000, the second item is unchanged, the third item "speed enable" is changed to 57600 and then restarted, everything will be fine.

7. Parameter infrared transceiver type changed to vishy 6101e

min.....change to 5.0ms

speed enable to 1152000
