TTL 5V Output (6): The TTL 5V output signal is intended to be used as a method for synchronizing
external data acquisition systems. The TTL goes high 60 µs before stimulating, and goes low once the
stimulation sequence is complete.
If you have a Stim Switch System, the TTL 5V output can be connected to an Enable In port on the
front panel of the Stim Switch Control Module and used to enable/disable single or multiple banks of
the stimulation connections simultaneously.
TTL Trigger (7): This feature has not been implemented in the current version of the CereStim R96.
The TTL Trigger is intended to provide the user with a method for using external devices to trigger
when the CereStim R96 sends a stimulation pulse. This feature will be implemented in future
firmware updates of the device.
Emergency Off (8): The emergency stop jack is used to attach an emergency stop switch (not
included) if emergency stop capabilities are required for your application. When activated, the
emergency stop controller will shut off all power to the CereStim R96 unit. The CereStim R96 is
designed for use with Normally Closed (NC) Emergency Stop Switches.
2.2 CereStim R96 Back Panel
The CereStim R96 Back Panel interfaces the CereStim R96 either directly to electrodes or to a
Blackrock Stim Switch system. The user is responsible for supplying any cables necessary for direct
connection to the electrodes.

CereStim R96 Cable Connectors (9): Connectors A-C provide a connection between the CereStim
R96 and the Stim Switch/Electrodes. Connector A corresponds with electrode output channels 1-32,
connector B with channels 33-64 and connector C with channels 65-96. Instructions for connecting
the CereStim R96 to a Switching System are provided in Section 4 below. The layout of the CereStim
R96 Cable Connector is shown in Figure 2-4 below.
