USB I/O Configuration
You can configure the USB port by “right-clicking” or “control-clicking” the “Unit Status Display” box.
Select “Set Number of Channels for USB…” as shown below.
Figure 10.90: “Set Number of Channels for USB…” selector
This will open the “USB I/O Configuration” window. The box model and serial number are displayed in the
header at the top. Below the header are pull-down menus from which to independently set the number of
Input and Output channels available at that USB port. This allows you to trade off USB channel count for
higher sample rates. “Maximum USB S/R:” will reflect the highest supported sample rate based on your
channel count selections:
• 4-12 channels works up to 4x rates (44.1k - 192k)
• 4-24 channels works up to 2x rates (44.1k - 96k)
• 4-48 channels works only for 1x sample rates (44.1k - 48k)

USB I/O port channel configurations remain persistent to that unit even after it is powered down. This lets
you pre-configure a 3d box for use on a PC or Linux box. Just remember, as noted above, the sample rates
available to the new computer will be limited by the number of USB I/O port channels you set.
Important!
In all cases
, the MIOConsole3d application maintains control over all 3d units which
appear in the Status Pane, and the 3d unit USB ports are slaved to the Domain sample rate and
clock. Changing USB I/O channel allocations or Domain sample rate will trigger a reset of the
USB port, and may (probably) require re-assigning your audio driver connection on the external
“Satellite Computer Port” device.
Connecting an Apple tablet or smartphone to 3d USB requires a ‘Lightning to USB Cam-
era Adapter’ or it's equivalent. Android users need a
-compatible cable or
adapter. Both of these solutions enable ‘USB Embedded Host Mode’ in the phone or tablet,
which is necessary to communicate with the 3d USB port. These adapters are commonly used
to connect digital cameras, USB flash drives, mice and keyboards to your Android or Apple
portable device.
Please note that due to the immense and ever-expanding landscape of computers, smartphones
and tablets which include some form of (often poorly documented) USB interface, the vast
majority of configurations have not received substantial testing.
