VID 
EN

Monitor KVM CAT5 
video interface

Orange - Lights when an internally-
generated signal is used. This occurs 
when the user is not connected to the 
port and in the OSD, or when the user is 
connected to a port, but a video signal is 
not present from the server.

Green - Lights when the server's video 
signal is used; this happens when the 
server is presenting a valid signal.

SYN

Monitor KVM CAT5 
video interface

Green - Lights when the user is 
connected to port and a video signal is 
detected and "synchronized". This 
means that the KVM is presenting the 
signal to the station. 

Orange - Lights when the video signal 
level is detected but not synchronized. 
Typically, this takes a very short amount 
of time (less than 1/3 second) for the 
KVM to synchronize to the server's 
video signal upon first connection.
