2.5 External Gating of the Stim Switch using the Enable In input
1. Connect the Stim Switch as described in section 2.4.1.
2. Connect The Stim100 to the desired banks of stimulation channels on the Stim Switch
Control Module as described in section 2.4.2.
3. Using the StimComm software, select the desired channels for stimulation by checking the
boxes next to the electrode numbers and pressing the ‘Set Electrodes’ button. Electrode
numbers can be selected independently for each bank of stimulation channels by selecting
the tabs at the top of the window.
4. Connect a control device to the Enable In inputs using a BNC cable. The control devices can
be any device that toggles between 0 V and 3.3 V (2.5 V and 5 V devices can also be safely
used). Here are a couple examples of devices that could be used:
• The TTL Sync Connector on the back panel of the Stim100.
• A function generator set to generate a 3.3 V square wave.
• A toggle switch that is connected to ground (0 V) when closed.
5. Stimulation is enabled by pressing the ‘Set Stim’ button in the StimComm program.
6. The Stim Switch will now set the Headstage to recording mode whenever the Enable In
voltage is low (0 V) and will set the Headstage to stimulation mode whenever the Enable In
voltage is high (≥ 2.5 V)
