IZ2M/IZ2MH Stimulator
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). See “IZ2M/IZ2MH Stimulator Technical
Specifications” on page 7-31, for pinouts.
Power on.
Power on the RZ base station, then power on the stimulator by pressing and holding
the small square button to the left of the status lights. After one second, release the
button.
The stimulator is powered on using battery for operation.
Important: The IZ2M/IZ2MH uses mains power for charging. Connect the power connector on
the back panel to a mains power outlet, using the provided AC power cable. The
battery is always charging when the mains power switch is in the ON position,
regardless of whether the IZ2M/IZ2MH is turned on.
When battery power is turned on, the blue LED on the mains power switch, to the
right of the status button, will be lit even when the mains power is off (used to
indicate temperature). Verify whether mains power is on or off by looking at the
position of the switch and by looking at the left-most power status LED. It will be
red when the device is using battery power or green when the device is using Mains
power.
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.
Arming Sequence
Before the stimulator can be armed the RZ2 must be connected to the stimulator
and powered on. 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—turn power on.
When the device is powered on (see above) the blue LED blinks until the device
comes up to optimal temperature. This can take up to 10 minutes. If no faults are
found at start-up, the stimulator may be armed before optimal temperature is reached
(not recommended).
If a safety fault condition is found at start-up; the blue LED will blink at 1 Hz and
the yellow LED will be off.
If a communication error, such as no signal detected from the RZ device, is found;
or the RZ is trying to actively stimulate, the yellow Ready LED will blink.
