In SafeCom Go Canon version 20*15 there is a problem if the Location field is empty on the Main Canon webpage. The SafeCom Go Canon version 20*15 will copy the location value from the main Canon webpage to the Location field in the SafeCom Go Canon configuration page. If however the Main Location field is empty, then a null value string is inserted in the SafeCom Go Configuration location field.
This null value string results in a Http: 500 error when attempting to open the SafeCom Go Canon Configuration page in an Internet browser.
The problem is fixed in version 20*16
How the problem looks like:
The workaround is either to ensure that the Location field in the Main Canon webpage is filled out, or manually use scdevutil(SafeCom Device Utility program), to add in a Location value in the SafeCom Go Canon setting.
Either workarounds will bypass the Http: 500 error.
- First Workaround: Ensure that the location field on the Canon main webpage is not empty:
 - Login at the Canon device webpage: 
example - If prompted for login, make sure to login as an administrator
 - When Logged in, then In the right hand side of the screen, click the Settings/Registration
 - In the left hand side, in the Management Settings section, click the “Device Management”
 - Then click the “Device information settings”
 - Make sure to fill in something, like “Building 4 basement” or the like
 - When text has been entered in the Location field, click the OK button in the upper right corner.
 - Done.
 - Second workaround: Ensure that the Location field is filled out in the Configuration part of SafeCom Go Canon using scdevutil
 - From your SafeCom server go to Start, Run, and type in scdevutil <Enter>
 - The SafeCom Device utility program starts up.
 - In the Device utility, type in the IP. Adr. of the Canon device, and click Add
 - The device is then added to the list.
 - Now rightclick the newly added device and choose “Edit Configuration”
 - Scroll to the <Device> <Location</Location> section and fill in a string value e.g. like this:
 - And hit the Update button.
 - If prompted for login, login as admin and most likely nimda as password.
 - Device is getting configured:
 - And when done, you can press the OK button,
 - And then press the Cancel button to return to the device list overview.
 - The SafeCom Device Utility can then be closed.
