Check that the Headstage Module is recognized. The Headstage Module LED for each
bank that is in use on the Stim Switch Control Module should be green. If it is red try
disconnecting the Stim Switch cable and ensuring that both ends are plugged into the
Headstage Module and the Control Module correctly. They are keyed and should only be
inserted one way.

Watch the light above the USB port on the Stim Switch when you send a command. It
should flash green briefly when the command is sent. If the light doesn't light up or is
red, try disconnecting and then reconnecting the USB A-B cable making sure that both
ends are fully securely plugged into the ports.
4.
Check which COM ports are available on your computer. Right click on “My Computer” in
the Start menu in Windows and select Manage->Device Manager. Find the Ports (COM
& LPT) category and open the subtree to find which ports are available on your computer.
Try switching the USB A-B cable to a different port and changing the port assignments in
the StimComm settings menu. Reinstall the Stim Switch USB drivers from the CD.
