If you want to remotely control and manage the display with the RS-232 Serial interface, attach
one end of an RS-232 cable to the RS-232 input (5) port (With the display lying on its face, the
input port is below the output port) and connect the other end to the serial interface port of the
media player/computer.
If you will be connecting more displays in a series (daisy chain), connect one end of a second
RS-232 cable to the output (upper) port of the display and the other end of the RS-232 cable to
the input port of the next display in the chain. (See
Connecting multiple displays to one player
for more details).

The USB port is for attaching a color-calibration device such as the HP DreamColor Display
Calibration Solution and is also used in the event of a firmware upgrade. Neither USB device is
plugged in until the time of use. However, if access to the USB port (6) will be limited once the
display is mounted, you can attach a USB extension cable now.
