Cakewalk for DOS Installation
Cakewalk for DOS Version 4.0 (and later) supports the use of
Installable Port Devices (IPD). You will need Portman PC/S IPD
from the Midiman supplied disk. The filename is PMANSCW.DRV.
Note: There may be several PMANS.DRV files for various pro-
grams. Make sure that you have the IPD for DOS Cakewalk by
using the DOS TYPE command on the file. The first 3 characters of
the file should be “IPD.”
In order to install the Portman IPD driver, you need to copy the
PMANSCW.DRV driver into the directory in which your Cakewalk
.EXE file lives, and rename it MIDIPORT.DRV. After doing this,
when you next start Cakewalk for the first time, use the /S switch
to allow set-up of the Portman MIDI interface parameters, specifi-
cally the COM port number.
Self (Parasitic) versus DC Powered
Portman is designed to run “parasitically” from the power available
at the host computer’s serial port thus requiring no external power.
A 9 Volt DC 300 mA center positive power supply can be purchased
from most electronics supply stores. When the adaptor is plugged
in, Portman automatically uses power from the adaptor rather than
from the computer.
Warning: Do not connect the optional power adaptor to the
Portman when it is plugged into your computer and the computer
is turned on. Doing so may result in damage to Portman and/or
your computer. Instead, turn the computer off and then plug the
power adaptor into the Portman.
Although Self (Parasitic) Powered is the preferred mode of opera-
tion, there are a few situations in which you might desire to run
your Portman using the external power adaptor including:
• If you are using a laptop or notebook computer and would like
