System Hardware
The PZ5M neurodigitizer accepts inputs from a variety of electrode/headstage
combinations via the back-panel connectors. It includes up to eight DB80 connectors,
each inputting 64 recording channels (or 32 differential channels) along with ground
and reference.
Recorded signals are amplified, digitized, and then transmitted via fiber optic
connection to the RZ base station for further processing. Configuration information is
also sent from the RZ to the PZ5M neurodigitizer across the same fiber optic
connection. The PZ5M-512 uses two of these connections, each transferring data for
up to 256 channels.
The PZ5M can connect to:
•
•
A standard system configuration includes electrodes appropriate to the input signals, a
connection manifold, PZ5M neurodigitizer and an RZ base station.
The diagram below illustrates this flow of data and control information through the
system.
Hardware Setup
Up to two 5-meter paired fiber optic cables (up to 256 channels per duplex cable)
are included to connect the neurodigitizer to the base station. The connectors are
color coded and keyed to ensure proper connections.
The diagrams below illustrate the connections necessary for PZ5M neurodigitizer
operation.
The Medically Isolated NeuroDigitizer is available with up to 512 channels. Two fiber
optic ports are available on the back panel for transferring digitized channels to the
RZ device. The first 256 channels are handled by the primary fiber optic port and
the second 256 channels (257-512) are handled by the secondary fiber optic port.
The connection to the processor can be made in a number of ways, including using
the standard PZ Amp Port for the device (RZ2 shown below) and a RZDSP-P port
mounted in the back panel of an RZ device. Note: The front panel optic port on the
RZ5D is an RZDSP-P port.
