M-AUDIO MIDISPORT 8x8/s - Manual (Page 18)

To command the MIDISPORT into Interface Mode using the USB connection and
drivers:
1. Power up the MIDISPORT while connected to the PC or Mac host computer’s
USB port, then select USB mode by pressing the Mode switch on the front
panel. The USB LED will blink, indicating that the MIDISPORT is not yet in
Interface Mode, but rather in stand-alone (Patchbay) mode.
2. Power up the host computer. Once the computer’s USB port recognizes the
MIDISPORT and starts communicating with it, the MIDISPORT USB LED
will begin to pulse. The MIDISPORT then exits its patchbay operation.
To command the MIDISPORT into Interface Mode using the serial port
connection and drivers:
1. With the host computer ’s power off, power up the MIDISPORT while
connected to the PC or Mac host computer’s serial (COM) port.
2. Then select PC or Mac mode (according to the computer in use) by pressing
the Mode switch on the front panel. The PC or Mac LED will blink, indicating
that the MIDISPORT is not yet in Interface Mode, but rather in stand-alone
(Patchbay) mode.
3. Power up the host computer. The MIDISPORT will be commanded into
Interface Mode by that host computer only by launching a MIDI application
that utilizes the MIDISPORT driver. Launching the Remote Control software
will also put the MIDISPORT into Interface mode. Once in Interface Mode,
the patchbay functions turn off.
Stand-Alone Modes
When not in use as a MIDI interface, the MIDISPORT 8x8/s operates in "Stand-
Alone" mode. The stand-alone mode is active whenever:
1. the MIDISPORT is powered up but disconnected from the computer, or
2. the MIDISPORT front panel mode is set to "Cable Test" or "Thru Mode", or
3. the MIDISPORT is connected to the computer but the front panel USB, PC, or
MAC mode does not match the driver installation/settings on the host
computer.
When standing alone, the MIDISPORT provides several functions:
• MIDI Patchbay. When the MIDISPORT mode is not set to "Cable Test" it
provides MIDI patchbay functions, routing any combination of MIDI Input
streams to each MIDI Output port.
• THRU Mode. This mode is selected via the front panel Mode pushbutton. It is
actually a special case of the MIDI patchbay, where every MIDI message received
at any MIDI In port on the MIDISPORT will be output on all MIDISPORT MIDI
Out ports. This is useful in diagnosing a system connection problem.
