3.2 USB connections for programming the Compute Module
To program the Compute Module, an external “host” PC is connected to the USB2 output and the display
is placed into the special “USB Boot Mode” using the OSD. The Compute Module will then appear as a
USB device to the “host” PC, allowing the Compute Module to be programmed.
When not used for programming the Compute Module, the USB2 output on the display can be used to
control the display via USB from an external PC; depending on the
PC SOURCE
setting in the
Control
USB
function on the display’s OSD menu.
See Related OSD on page 43.
