However, when any network wants to switch to another network, for example, when it wants to connect to the media server 420, the network information set for connecting to the host computer 410 has been stored in the MIRA software , so the user does not need to back up the network information set for connecting to the host computer 410 in the registry. If you need a backup, you can use the BackupMiraConfig() function.

If the mobile monitor 430 is to be connected to the host computer 410 again later, the user can select the service identification code of the media server 420 set in the main location in the basic setting network dialog box 521 displayed by the mobile monitor 430 . This process is carried out according to the RestoreMiraConfig() function.

In this way, the identification code of the host computer 410 is in the main position of the basic setting network dialog box 521, and the mobile monitor 430 has just realized the connection with the above-mentioned host computer 410 according to MIRA.

If want to change from being connected to the host computer 410 to being connected to the media server 420 again, the user only needs to select the identification code of the above-mentioned media server 420 in the available network dialog box 522, and log in to the basic network dialog box 521 , the mobile monitor 430 can be wirelessly connected to the above-mentioned media server 420 . At this time, the wireless network setting information of the media server 420 is read from the meter. This process is carried out using the RestoreMEDIAConfig() function.

That is, in the embodiment of the present invention, even if the user does not delete the setting information of the host computer 410 set as the basic network, by only adding the network setting information for connecting to the media server 420, it is also possible to realize mobile monitoring. The device 430 is wirelessly connected to the media server 420. Afterwards, when connecting to the host computer 410 again and then connecting to the media server 420, the user does not need to reset the network information of the media server 420, but only needs to use the above-mentioned media server 420 stored in the registration form. network information.
