4. Checking Software Version of US40a
To check the version information on US40a, select [Start]

[Control Panel]
→
[Version
Information].
NOTES:
„
US40a manages internally the versions of common.txt, certificates
(.cer or others) and background image (.bmp) based on the time at
which each of the files is created. For example, assume that US40a
once read common.txt (created at 13:15 on November 15, 2007)
uploaded to an FTP server. US40a will no longer read the
common.txt having the same created time as long as US40a
accesses to the same FTP server even if auto update on booting has
been specified.
„
When the download server is changed, US40a may read common.txt
of the same created time again. This is because, if the download
server is changed from one to another, the created time of
common.txt obtained from a server may be different from that
obtained from another depending on the protocol and time zone of
each of the pre-change and post-change servers.
„
By the default setting of US40a, auto update on booting is enabled
and DHCP options 161, 162, and 163 are specified. If option
numbers 161, 162 and 163 are already used for other purposes in the
network system that uses DHCP options, you need to change the
update settings of US40a.
