Optionally, a
fi
ber optic rotary joint with single-channel optical
fi
ber assembly may be added
(shown above) to allow optical targeting and excitation on neural circuits for artifact free
stimulation. The optical assembly is user serviceable to allow for easy optical
fi
ber
replacement.
Part numbers:
ACO32 - 32 Channel Commutator
ACO64 - 64 Channel Commutator
FORJ - Fiber Optic Rotary Joint and Fiber Optic Cable
Power and Interface
The ACO32 has a rechargeable 1950 mAh Li-ion Battery. The ACO64 has a 3900 mAh battery.
A 6-9 V, 3A, center negative adapter (one provided) charges the device. Low battery status is
reported only by a decrease in rotational speed.
ACO32 Hardware Setup
The commutator is mounted above the subject. A PZ preampli
fi
er is connected to the DB26
connectors marked A and B on the face of the commutator. A headstage (with splice
connector) and a splice-to-splice adapter are connected to the interface receptacles on the
connector module. See
below for more information on this
connection.
