Once in the program, you can press your computer’s <Enter> key
to toggle through the COM Port setting until it matches your setup.
If your COM port is not at the default setting (Normally, COM1 is
IRQ 4, Port Address 3F8 and COM2 is IRQ 3, Port Address 2F8),
you can use the down arrow key to move down one line and set the
program IRQ to match your port’s setting by again using the
<Enter> key to cycle through the available choices. Then move
down one more line and use the same procedure to set the I/O
address.
Next, connect a single MIDI cable between the MIDI In and MIDI
Out on the Portman PC/S. This cable will be used to “loop back”
data and verify MIDI transmission/reception.
IMPORTANT: When performing this test the MIDI In MUST be
connected to the MIDI Out on the Portman.
Move the cursor down to the “Run Tests” line and press <Enter>.
The program should run through 4 tests. If it fails any of these
tests, go back and make sure that you have followed the above
instructions exactly.
PCSDIAG.EXE
will test the following four areas:
1. Hardware.
This will indicate whether the Portman, your computer, and the
RS/232C cable are all connected properly and working correctly.
If your Portman fails this test, it could mean a bad Portman or other
hardware failure, but most often it means one of the following
things is amiss:
a.) You have the incorrect port settings in the PCSDIAG command
line.
b.) You need external power.
c.) Your cable doesn’t support hardware handshaking.
2. MIDI Input/Output
If your Portman fails this test, it indicates a bad MIDI connection. It
could also be an indication of a specific communication problem.
