Config port — This USB mini-B port serves a similar
A
communications function to the rear panel Remote port, but
is easier to access than the rear port after the matrix switcher
has been installed and cabled. Use a USB type A to mini B
cable to connect this port to a USB connector on the computer
to enable SIS commands to be sent from the computer,
connection to the PCS configuration software, and uploading
firmware.
NOTE: A front panel Config port connection and a rear
panel Remote port connection can both be active at the
same time. If commands are sent simultaneously to both
ports, the command that reaches the DXP first is handled
first.
For more information about this port, see
Port
on page 12.
