The Stim100 is a fully programmable current generator with 96 output channels and the capability
of producing up to 16 simultaneous stimuli. When the Stim Switch is set to stimulation mode,
current generated by the Stim100 passes through the Stim Switch and provides stimulation to a
set of selected electrode channels.
Subject Ground (9): The subject ground should be connected to the Subject
Ground connector. Internally the Stim Switch provides a minimum isolation of
500 VACrms between the subject ground and chassis ground.
Power Connector: The power connector (Figure 2-4) on the back of the Stim
Switch is capable of 120-240 V AC input. Please confirm that the Stim Switch is
set to the appropriate voltage before plugging it in for the first time. There are
two fuses in the power supply that may need to be replaced if the Power Supply
is connected to the wrong voltage. Connect the Stim Switch to a wall outlet
with the provided 3 prong power cord. The power cord is to be used for mains
disconnection.
2.2 Interconnection/Headstage Cables
Interconnection Cables: The Interconnection Cables provide a connection between the
Stim100 neurostimulator and the stimulation inputs on the Stim Switch.
Identifying Features: Black, round and approximately 10 feet in length with a DB37
connector on one end and a 40 position socket connector on the other
Connections: The DB37 connector connects to one of the 4 Stimulation Connectors on
the front panel of the Stim Switch (see Section 2.1); the 40 position connector connects to
one of the Stim100 Cable Connectors on the back panel of the Stim100.
Headstage Cables: The Headstage Cables provide a connection from the Stim Switch to an
individual Headstage within the Stim Switch Headstage Housing (see section 2.3 below).
Identifying Features: Black, round, covered in an expandable mesh sleeving and
approximately 3-6 feet in length with a DB50 connector on one end and a 50 position,
double row, socket connector on the other.
Connections: The DB50 connector connects to one of the 4 Headstage Cable Connectors
on the front panel of the Stim Switch (see Section 2.1); the 50 position connector connects
to the 50 pin connector on one of the heastages within the Stim Switch Headstage Housing.
Use caution when making this connection. The connection is keyed, but it is possible to
partially plug the cable(s) in backwards.
2.3 Stim Switch Headstage Housing
The Stim Switch Headstage Housing encases up to 4 Headstage
Modules. Each Headstage Module provides a connection
between the Front End Amplifier, the implanted electrodes, and
the Stim Switch.
Each Headstage Module within the Housing connects to the Stim
Switch with a separate Headstage Module Cable. The power
switch on the Stim Switch should always be
turned off prior to connecting or disconnecting a
headstage module cable.
