This fast facts sheet provides basic reference
information for the IZ2M/IZ2MH Stimulator and
related devices. See the System 3 Manual for more
detailed information.
The stimulator is available with 32 or 64 channels
and standard (M) or high current (MH) versions.
Output Voltage +/- 12 V
IZ2M Output Current +/- 300 µA up to 40 kOhm load
IZ2MH Output Current +/- 3 mA up to 4 kOhm load
Arming Sequence. Before the stimulator can be armed the RZ
processor must be connected to the stimulator and the battery
should be fully charged. If the stimulation circuit is loaded and
running, it MUST NOT be actively sending stimulus signals on any
channels.
The instructions below provide step-by-step sequence and more
detail about each stage of device operation.
Step one. Boot—Press the battery power button to power on. The
blue LED on the mains power switch blinks until the device comes up to
optimal temperature.
See the LED Indicator table to the right for safety fault or communication
failure LED light patterns. When all safety checks have passed, both the
blue (Power) and yellow (Ready) LEDs will be lit (no flashing), indicating the
device is ready to arm.
Step two. ARM—Hold down the Start/Stop button for 3 seconds.
When the red LED flashes the Start/Stop button may be released and the
red (Armed) LED will remain lit. See the LED Indicator table to the right for
fault LED light patterns.
Step three. Stimulate—Send stimulation (up to 10 channels) from
the RZ processor. Once the device is armed, by default all channels are
open and open/close state can be controlled from run-time applications.
The stimulator will deliver stimulation to the subject whenever stimulation
signals are received from the RZ processor.
The stimulator faults and returns to safe mode (all channels open/no
curent output possible) if either of the below occurs:
• Stimulation is attempted on more than 10 channels.
• More than 100 mA total output is detected by the compliance board.
Note: It’s not possible to reach 100 mA under normal conditions.
Step four. STOP—Press Start/Stop button. Press the Start/Stop
button at any time to stop stimulation immediately and revert to safe
mode.

System Set-up. Before connecting the system
hardware, ensure that the TDT drivers, PC interface, and
RZ and zBus devices are installed, setup, and configured
according to the installation guide provided with your
system.
Connect to power. Connect the power connector on
the IZ2M/IZ2MH back panel to a mains power outlet
using the provided AC power cable. Using the mains
power switch on the front panel, set to ON to charge the
battery or set to OFF for battery operation.
Connect the stimulator to the RZ base station using the
provided duplex fiber optic cable.
Connect the fiber optic cable from the stimulator’s fiber
optic port labeled Fiber to the fiber optic port labeled
To IZ2 on the back side of the RZ. Use the RED labels to
match up the color coded fiber connectors and be sure
to line up the notch and keys on each.
Connect electrodes. Connect the DB26 output
connectors on the stimulator to the stimulating
electrodes using your preferred method such as direct
wiring or a custom pass through connector (available
from TDT).
Power on. Power on the base station, then use the
battery power button on the front panel to power on the
stimulator. The hardware is ready for use.
If using the system with other devices, or preamplifiers,
see the documentation for those devices for hardware
connection information.
Note: Contact TDT technical support (386-462-9622
or [email protected]) before attempting to make any
custom connections to pins 6, 18, or 19.

Synapse Rig Configuration. The first time the
IZ2M 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.
