Certificate warning shown while connecting via HTTPS.
It is normal for a warning dialog to be shown when connecting via HTTPS. The SSL certificate we use
is created when the unit is first produced. It does not contain the correct hostname (subject name)
because you can change the hostname as required. Also, it is not signed by a recognized certificate
authority (CA) but is signed by our own signing authority. For more details, refers to “Appendix F:
About Security Certificate Warnings”.
Windows XP doesn't awake from standby mode.
This is possibly a Windows XP problem. Try not to move the mouse while XP goes into standby mode.
The terminal connection to Digital KVM via IP for initial configuration cannot be established.
Check that the Null Modem cable connected to DTE Serial Port on the Digital KVM via IP and
terminal software is set to the following line parameters:
Connection speed: 115200 bps
No. of bits: 8
Parity: None
Stop bits: 1
Flow Control: None
Connect computer to the Digital KVM via IP and power this computer on. Power on the Digital KVM
via IP while pressing the ESC key on the keyboard connected to it. This will switch the DTE Serial Port
to Configuration Login setting even if it was set to Pass-through or Modem.
Also, Windows HyperTerminal has a bug: if you change baud rates while connected, the screen is
updated but the hardware is still at old baud rate; hang up and reconnect (using icons at top of screen)
to make new settings take effect.
If my network has a firewall, what setting do I use on the IP Extender to open a port into the
network?
You shouldn't change any settings in the Digital KVM via IP, but you should open port 22 for both
outbound and inbound connections in your firewall.
Port 22 only needs to be opened for inbound connections. You must use SSH tunnel to connect to
machine; tunnel to port 192.168.1.123:5900 for VNC protocol, and 192.168.123.1:80 for HTTP (web)
control.
OR, instead of SSH client, open ports 443 and 15900 (inbound) for HTTPS and encrypted VNC
protocol. Then click always on the "encrypted" link. This is easier because you don't need to setup
SSH tunnels.
