The diagram above shows the ACO32 connection for the A subset of channels:
from headstage (with SPL16 analog or SPL16-D digital connectors)
to splice-to-splice connector
to commutator receptacle
to ampli
fi
er connection cable.
Channel numbers correspond to the ampli
fi
er bank of channels to which the cable is
connected. For example, if the 'A' connector is connected to Bank 'A' on the PZ5 preampli
fi
er,
channels are numbered 1 - 16.
Ampli
fi
er Connections
The ACO commutator interfaces with a PZ ampli
fi
er via two or four DB26 connectors, 16
analog channels each) on the face. Adapter cables may also be used for connections to
Medusa Preamps.
See
for connector pinout.
Fiber Optic Rotary Joint
The
fi
ber optic rotary joint (FORJ) assembly is an available add-on component. It includes an
FC/FC optical
fi
ber connector accessible on the commutator face and a single channel optical
fi
ber threaded through the module. The default
fi
ber optic cable included with the system is
200 um core diameter, 0.22 NA, with a 1.25 mm OD metal ferrule. FORJ is also compatible with
branched optical
fi
bers of up to four bundles in the ACO64.
Replacing the Optical Fiber (ACO32)
The FORJ assembly can be removed and re-installed by the user to replace the optical
fi
ber.
To remove a currently installed FORJ:
Use a 3/32" Allen hex driver to remove the two screws securing the
fi
ber optic rotary joint to
the commutator face.
