System 3
Note: The motor in the ACO64 commutator does not disengage like the ACO32. The
ACO64 has an additional hardware mount on the bottom, below the headstage
receptacles, facing the subject.
ACx Setup Notes
Dimensions and form factor for ACx commutators not pictured. Before using the
AC32 and AC64 commutators, adjust the wire harness to ensure it is balanced. The
AC32 harness should be in two loops 180 degrees apart and the AC64 harness
should be in four loops 90 degrees apart. Typically, preamps are connected to the
connectors on the face of the commutator and headstages (with special splice
connectors) are connected to the interface receptacles.
Features
LEDs
The four indicator LEDs on the front panel indicate power, the status of the Inhibit
BNC input, clockwise rotation and counterclockwise rotation.
Manual Rotational Buttons
The commutator features both clockwise and counterclockwise manual rotational
buttons. When pressed, these buttons will rotate the commutator at approximately 18
RPM. Pressing either of these buttons also overrides the current rotational state of
the commutator.
Inhibit BNC
During critical recording periods it may be necessary to prevent rotation to ensure
signal integrity. A logical low (0) on the Inhibit BNC will prohibit any rotation
initiated by either the sensors on the commutator or the manual rotational button.
External Ground
A banana jack located on the face (GND) provides connections to common ground
on the commutator.
