The
Regrab Screen button in the Actions section causes the screen to
be re-captured. When making small changes to the video parameters,
sometimes these changes are not reflected in the displayed screen imme-
diately, particularly if the noise filter is enabled. Press this button to see
the immediate effect of the changes.

Use the
Show Diffs button to learn which parts of the screen are being
sent over the Internet. When you click this button, the screen is cleared to
a medium grey color. All blocks that are sent from that point on will show
up on the screen as they are sent. Click the button again to reset the
screen to grey. To return to normal operation, click the

Using the Modem feature
Background
The modem feature allows the SV441DUSBI to act as an Internet con-
nection server for increased security and flexibility in connecting with
the host computer. Unlike the TCP/IP connection used with the standard
Web configuration and VNC clients, the modem creates a one-to-one
connection between the SV441DUSBI and the computer you are using to
manage the host computer that is essentially private, as it bypasses the
public Internet completely.

Note: this feature requires both an external
modem (most standard connection protocols are supported) and a
dedicated phone line that can be connected to the modem for external
access. While it is possible to use the modem feature through some PBX
systems, this increases the complexity and reduces the performance of
the connection. For clarity, the instructions presented here assume that
the modem is connected to a typical POTS (plain old telephone system)
line that is not routed through a phone management system or shared
