Operating Notes
• If the power supply to the R-Port modules you have connected becomes faulty (short,
overload) then the R-Port LED on the front panel of the SVxx41HDIE will show red.
Under normal operations, this light should remain green. The R-Port connector on the
rear panel also has an LED that mirrors the status of the light on the front panel.
(Note: The rear LED status was reversed on some early units, where red=normal and
green=fault. This does not affect operation in any way, but a green LED on the front
panel and a red LED on the rear panel indicates that you have one of these units.)
• Hardware handshaking (CTS/RTS) is required for speeds exceeding 9600 bps. It is
enabled by default on the SVxx41HDIE, but may need to be enabled on the other end
of the connection. For Unix systems, the command is:
stty –crtscts < /dev/[serial port]
• A maximum of four users may simultaneously login to the same module. All users may
type commands at any time, and all users will see the same output. Note the following:
• All users have equal access to all channels.
• A maximum of 16 R-Port modules may be connected at any one time.
• You plug-in and unplug any R-Port module at any time. When reconnected, it
will automatically become available after a 15 second initialization period. Any
log entries will be retained by the R-Port module while deactivated, but will not
be available to users until it is re-initialized.
About Security Certificate Warnings
What is a security certificate?
Sites that employ secure TCP/IP (Internet) connections include a certificate that confirms
that users are connecting to a legitimate site and are not being redirected without their
knowledge. Certificates are issued by trusted third parties called Certificate Authorities
(CAs) and contain essential details about a site that must match the information supplied
to your Web browser.
Why do I receive a warning when I access the login screen on the SVxx41HDIE?
As it redirects you to a secure (SSL) session by default, the login screen may generate a
warning from your Web browser or the VNC Java client for two different reasons. First,
the CA that has issued the certificate on StarTech.com’s behalf may not yet be
recognized as a trusted source by the computer you are using to access the
SVxx41HDIE. Second, since the unit could be configured in a number different ways, it
is impossible to supply a generic certificate that will match your exact network settings.
Is my data safe?
Yes. The security certificate does not affect encryption effectiveness in any way, nor
does it make the SVxx41HDIE any more vulnerable to outside attacks.
