M-AUDIO MIDISPORT 8x8/s - Manual (Page 21)

LED will light steadily, indicating that the MIDISPORT is now functioning as a
MAC serial MIDI Interface.
When MAC serial mode is selected, you may select the MIDISPORT patchbay
program via the Remote Control software, or the MIDISPORT front panel RESET
pushbutton. Patchbay operation is described in detail in the "Patchbay
Operation" section of this manual. All SMPTE functions are also available when
the unit is operating as a PC MIDI interface. SMPTE Operation is described in
detail in the "SMPTE Operation" section of this manual.
Cable Test Mode
When the MIDISPORT is in Cable Test Mode, it will not function as a MIDI
Interface or MIDI patchbay, nor will it communicate with the host computer.
Cable Test mode is a stand-alone mode of the MIDISPORT. Consequently, the
remote control software will not be able to communicate with the MIDISPORT
either.
The MIDISPORT may be set to Cable Test mode by successively pressing the
MIDISPORT front panel Mode pushbutton switch until the Cable Test LED
lights. If you left one of the MIDI interface modes (USB, PC or MAC) to get to
Cable Test mode, it may be necessary if returning to that MIDI interface mode
from Cable Test mode, to restart your MIDI application or the remote control.
Once in Cable Test mode, the front panel MIDI In-8 and Out-8 ports can be used
to test a standard MIDI cable. Basically if the Cable Test, In-8 and Out-8 LED’s
are flashing, the MIDI cable is bad or not connected properly between In-8 and
Out-8. If the cable is good, the LED’s will turn on and remain on with no
blinking until either the cable is disconnected or has an error.
Thru Mode
Thru mode is actually a special case of the MIDI patchbay, where the program is
set to "all ins are available at all outs". In other words every MIDI message
received at any MIDI input port on the MIDISPORT will be output on all
MIDISPORT MIDI output ports. This is useful in diagnosing a system
connection problem. When the MIDISPORT is in Thru Mode, it will not function
as a MIDI Interface.
To enter this mode, press the "Mode" pushbutton on the MIDISPORT front panel
until the "Thru Mode" LED is lit. Thru mode can be selected on the MIDISPORT
8x8 at any time, either from an Interface mode or a stand-alone mode. It may be
necessary, if returning to Interface mode from Thru mode, to restart your MIDI
application or the remote control.
Although Thru Mode essentially overrides all other patchbay settings, the
MIDISPORT will still respond to patchbay program changes (On MIDI In-8
channel 16) or to the Reset button program change commands. When the
MIDISPORT has returned to Patchbay mode, this program change can be
utilized.
