Chapter 4: Enhanced Operation
M = USB Memory Option
Using the USB Memory Option command, the OSD provides the user with a cryptic
code to be sent to Black Box to enable the license key. Then you can attach USB
memory devices and transfer files.
Once the license is active, this command will enable or disable the file transfer
feature to restrict data transfer.
USB High Speed Memory Option
Enable: send ID to
distributor
ID = 3fe687d5
Figure 4-2. USB high-speed memory option.
NOTE: Once the memory device option is enabled, using the extender on top of a
KVM Switch might cause compatibility issues since the USB mode will be
changed from low speed to high speed protocol.
L = Lock Menu enabled/disabled
Once enabled, you can only enter the OSD during the first 10 minutes after the
remote unit powers up. It will be locked afterwards.
