This fast facts sheet provides basic reference
information for the IZ2/IZ2H Stimulator and related
devices. See the System 3 Manual for more detailed
information.
The IZ2 Stimulator is available with 32(IZ2-32), 64(IZ2-64), or
128(IZ2-128) channels. Power for stimulation is supplied by 200
and 400 Wh battery life (LZ48-200 and LZ48-400) Li-Poly battery
packs, both capable of producing the same output voltage/current
characteristics. The number of channels needed for stimulation
determines power requirements. The IZ2H is a high current range
version of the IZ2 and is available with sixteen stimulus channels.
Output
Stimulus Output Voltage +/- 12 V
IZ2 Stimulus Output Current+/- 300 µA up to 50 kOhm load
IZ2H Stimulus Output Current +/- 3 mA up to 5 kOhm load
Power
IZ2-128 should only be used with the LZ48-400
IZ2-64 can be used with LZ48-200 or LZ48-400
IZ2-32 can be used with LZ48-200 or LZ48-400
IZ2H-16 should only be used with the LZ48-400
Synapse Rig Configuration. The first time the IZ2 is used,
it must be configured in the rig. When the specialized DSPI
card mounted in the RZ device is detected, an IZ2 will be
added to the rig hardware tree. Click the check box to the
left of the IZ2 icon to enable the device. In the options area,
select the model and number of channels.
Synapse IZ2 Options. Click the IZ2 in the Processing Tree
to display hardware option. Select Current or Voltage mode
and any other options as needed.

Important! Make
sure pins align
with connector.
1. Setup and configure the rest of your system.
2. Connect the battery pack cable to the back panel of
the stimulator via the connector labeled Battery, as
shown in the diagram below.
Warning!: Shorting the battery connection pins can
cause damage to the device and injury to the user.
Always use caution when handling or connecting the
devices.
3. Connect the stimulator to the base station using the
provided fiber optic cable.
4. Connect the fiber optic cable from the IZ2/IZ2H
fiber optic port labeled Fiber to the fiber optic port
labeled To IZ2 on the back side of the RZ. Be sure to
note the difference in the two sides of the fiber optic
cable connectors and ensure they are inserted with the
correct side up.
5. Connect the DB26 output connectors on the
stimulator to the stimulating electrodes.
