Selecting the USB Port
Unlike serial ports, USB ports are dynamic. That is to say that they are manifested when the PSC-USB is
connected, and extinguish themselves upon disconnecting.
If you are so inclined to witness this
phenomenon, simply open up the properties of the My Computer icon, then click on the Hardware tab,
then click on the Device Manager button. Once in the Device Manager, click on the small + sign next to
the Ports icon. Now, connect and disconnect the PSC-USB while watching the Ports list. For proper
operation, connect your PSC-USB to the PC USB port before launching the PSCI software.
To select a COM port, simply click on the File tab and hover the mouse over the Select Comm Port entry
to invoke the list of found comm ports. To choose a comm port, simply click on that comm port. If all
goes well, a message will report the successful opening of the comm port.
If you wish to confirm the presence of the PSC-USB, you may then click on File->Get PSC version. If the
PSC-USB is found, the version number will appear in the message window on the left side of the PSCI
screen. See below.
Controls Description
To control the servos in real-time mode, connect your servos to the PSC-USB and simply slide the power
switch on the PSC-USB to the ON position. Now, moving the corresponding servo position slide bar in the
PSCI software positions the servo.
