CHAPTER THREE - PL3000 BASICS
42
On Windows Vista-based computers this data synchronizing operation is not
referred to as ‘ActiveSync’, but the data synchronizing technology is embedded in
the part of a ‘Windows Mobile Device Center’ (WMDC) software package in the
Windows Vista system.
If you select the Mass Storage option, your PL3000
is seen as USB mass storage device by Windows-
based computer when it is connected to the computer’s
USB socket. What the Windows on your computer sees
is the Flash directory off the root of the Windows CE file system on your PL3000.In
other words, in this mode you can use your device – your device’s Flash directory,
to be precise – as a USB memory dongle.
RNDIS (Remote Network Driver Interface
Specification) is the protocol that the ActiveSync
communication has been based on since the release of
the version 4.0. The RNDIS mode on your device in combination with the
ActiveSync on your local Windows machine provides IP connectivity across the
USB serial bus.
Note! Microsoft has informed that a remote synchronization feature is
removed from the 4.x versions of ActiveSync (at least from 4.0, 4.1, and
4.2 versions) because the remote synchronization does not allow for a
strong authentication.
Volume & Sounds
Windows Embedded CE uses sound effects to indicate diverse occurrences in
the device to a user. The occurrences are classified into five categories: application
sounds, system events and warnings, alarms and remainders, keystrokes, and
touch-screen taps. With the help of a Volume & Sounds applet you can allow or
prevent the sound effects on a source-by-source basis. The applet refers to the
system events and warnings as ‘events’, and to the alarms and remainders as
‘notifications’. To the keystrokes it refers as ‘key clicks’. As far as the sound effects
of keystrokes and touch-screen taps go, they have three level volume control of
their own, and when you disable their sound effects, you actually mute their sound.
The Volume & Sounds applet also provides a volume control of a speaker
which affects all the sounds the system produces. In addition, there is a ‘Sound’
page by which you can have greater choice in enabling and disabling the event
sources, and the sound effects which you assign to them. The page also helps you
in selecting the sound effect for a particular event by giving you possibility to listen
the sounds available before you assign one of them to a particular event source.
After having made your choice for the enabled event sources and their particular
sounds, you can save your choice as a scheme file.
