General Problems
Reset the matrix by an LW2 command, or
unplug and reconnect the power cable.
Make sure the connectors fit well.
Select the desired/connected port.
Even though I/O boards are equipped with
DVI-I ports, only the indicated ports accept
analog signals.
Check the crosspoint state in the matrix.
Unmute the port.
Emaulate another EDID (e.g. Lightware's
Universal EDID).
For direct connection, use a cross-link
cable; for connecting the matrix to a hub
or switch, use a straight patch cable.
Check the settings of your computer and
make sure it is connected to the same
network as the matrix.
Set the IP address manually for a direct
connection.
Check the current IP address; set a
dynamic IP address if DHCP server is in
the network.
The matrix accepts LAN connection on
the 10001 TCP port.
Check the firewall settings.
Check the current protocol setting and set
the desired option.
