in Windows XP system After we prepare 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 one) Levels have to be advanced system and then plug usb infrared adapter, otherwise it will not find usb infrared adapter, this should pay attention. After plugging in, the system will prompt to find new hardware, and then automatically install the driver, the system will say that it can be used after the installation. At this point, 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, click "Properties" below, then Click on the "Advanced Menu" above. In the "Advanced Menu" we can click on the "infrared transceiver type" in the first line, then click on the value on the right to find three options such as sigmatel 4000. If we start here With 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 the Windows integrated drivers we use are mostly outdated and have limited support for new hardware. . 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 the manufacturer knows what program their hardware uses. The driver is the best, 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 the software automatically, but often smart Windows can't find the driver, it's 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 that there are several options. We choose "vishay 6101e[defau]" Yes. 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 an icon of mrouter. Double-click the mrouter icon and 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 that the 3650 memory is too small. The reason is that when the data transfer rate is fast, a 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 Windows default!), 115200 and other values, after many trials. , 57600 is the most ideal speed.
About the infrared connection:
1, the mobile phone's infrared adapter
rate is only 115200, and now the computer's infrared adapter up to 2m
If the speed does not match, it is easy to disconnect after 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 you choose infrared Yes, the old notebook infrared is taking up the com2 port, and some are virtual com3\\com4 port, you need to try one by one. On my notebook machine (win98), there is also a selection of infrared invalid, choose com3 effective. . 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. Because there are many types of external infrared adapters, the drivers are different, and specific problems need to be analyzed. 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 homepage, 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 the problem of setting, try different settings on the relevant settings panel, do not damage the computer or mobile phone, have a spirit of practice ! 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. The parameter infrared transceiver type is changed to vishay 6101e min..... to 5.0ms. Speed enable changed to 1152000 My Computer - Right Click - Properties - Hardware - Device Manager - Infrared Device - Properties - Change!
