Front Panel Configuration Port
A
Configuration port
— This USB mini-B port serves a similar
communications function as the rear panel Remote port, but it
is easier to access than the rear port after the matrix switcher
has been installed and cabled.
NOTE:
A front panel Configuration port connection and
a rear panel Remote port connection can both be active
at the same time. If commands are sent simultaneously
to both, the command that reaches the processor first is
handled first.
