2.3 Computer Setup

The Stim Switch connects to a USB port on

the computer through a standard USB A-B

cable. The StimSwitch uses an internal

USB to serial converter and will appear as

a COM port on your computer. Be sure

that the COM assigned by your computer

to the Stim Switch matches the COM port

settings in the StimComm Software (See

Menu Options in section 3 for instructions on changing COM port settings).

2.4 Hardware Setup

1. Unpack all components of the Cerebus Stim Switch.

2. Connect the USB port on the Stim Switch to a USB port on the computer with the USB A-B

cable that is included in the packaging.

3. Verify that the voltage switch on the back of the Stim Switch Control Module matches the line

voltage for your region.

4. Plug in the Stim Switch Control Module using the included power cable. Do not turn the

system on yet.

5. Plug in the Emergency Off Switch if required for your application.

6. Plug one end of the Headstage Cable into one of the four banks

of Headstage connectors on the Stim Switch Control Module.

Plug the other end into the Headstage Module. Be careful, the

connections are keyed, but it is possible to partially plug the

cable in backwards.

7. If you have a Fast Settle modified Front End Amplifier, connect

the Fast Settle BNC Cable from the modified Front End Amplifier

to the FS Out BNC connector on the Stim Switch Control

Module. If you do not have a Fast Settle modified Front End

Amplifier, you can continue without making this connection, but

you will be unable to record for approximately 3-5 s after

switching between stimulation and recording modes. Front End Amplifiers can also be

connected to any of the Status Out BNC connectors that correspond to Banks A-D for

independent fast settling.

8. Power up the system to verify functionality.

2.5 External Gating of the Stim Switch using the Enable In input

1. Connect the Stim Switch as described in the previous section.

2. Connect stimulation sources to the desired banks of stimulation channels on the Stim Switch

Control Module.
