Note: The PC diagnostic program may be run from either the “true”
DOS prompt, or from a DOS box in Windows. It will not operate on
a Mac computer.
To run the program, insert the MIDIMAN Drivers disk into your computer’s
disk drive. If your MIDISPORT came with a floppy disk, follow the instructions
that follow. If your MIDISPORT came with a CD, we suggest copying the
MS88DIAG file from the CD onto a floppy, and then following the instructions
that follow.
Verify you are accessing the proper disk drive by typing either “A: <Enter>” or
“B: <Enter>” at the DOS prompt. This should give you either the A:\> prompt,
or B:\>, depending on which drive letter represents your 3.5” floppy drive.
Once you see this prompt, type “MS88DIAG” and press the <Enter> key.
Once in the diagnostic program, you can press your computer’s <Enter> key to
toggle through the COM Port setting until it matches your setup. As you select
your COM port, the program will automatically setup the standard I/O address
and IRQ for that COM port. This will work for nearly all systems. Occasionally
custom-configured computers will require tweaking of the Address and/or IRQ
settings. To change these, use the <up> and <down> cursor keys to select the
Address and/or IRQ Number, then <Enter> to change that parameter’s setting.
Next, connect a single MIDI cable from MIDISPORT MIDI In-A to MIDI Out-A
(the front two MIDI jacks) of the MIDISPORT 8x8/s. This cable will be used to
“loop back” MIDI data - the MIDISPORT will transmit MIDI data from Out-A
and receive/verify it at In-A.
IMPORTANT: When performing this test be sure that MIDISPORT
MIDI In-1 and MIDI Out-1 are connected properly with a standard
MIDI cable. Otherwise the diagnostics program will indicate that
your unit is failing the test.
Now connect the SMPTE In jack to the SMPTE Out jack using a single standard
male-to-male 1/4” phone cable. This cable will be used to “loop back” and verify
SMPTE data.
Move the cursor down to the “Run Tests” line and press <Enter>. The program
should run through five separate tests. If any of these tests fail, go back and
make sure that you have followed the setup instructions exactly. Once the first
run of tests has passed, toggle the settings on the “Loopback” line of the
diagnostics screen to verify other MIDI input and output ports. Move the
connecting MIDI loopback cable to match the setting on the diagnostic program
screen and re-run the tests to make sure that all of your MIDISPORT inputs and
outputs are working properly.
