inputs. The PZ5 can support a total of up to 128 analog channels or up to 256 digital channels
or up to 256 mixed channel types. The total number of channels is generally reduced to 128 at
higher sampling rates, up to 50kHz. See
Sampling Rate and Digital Input Channels for more
information.
System Hardware
The PZ5 accepts inputs from a variety of electrode/headstage combinations via the back-
panel. Each analog board has a mini-DB26 connector that accepts 16 recording channels (or 8
differential channels) along with ground and reference. Digital boards have a 12-pin Omnetics
connector for Intan headstages and can accept up to 128 digital channels each. The PZ5 can
return at most 256 recording channels to the RZ base station.
Analog signals are digitized and transmitted to the RZ base station for further processing via a
single
fi ber optic connection. Con fi guration information is also sent from the RZ to the PZ5
across the fi ber optic connection. The PZ5 can connect to the 'PZ Ampli fi er' input on an RZ2
base station, or directly to any RZDSP-P card or optical QZDSPO quad card on any RZ base
station.
A standard recording con fi guration includes electrodes appropriate to the input signals, a
breakout box or one or more Z-Series headstages (such as ZC32), a PZ5 and an RZ base
station.
The diagram below illustrates this fl ow of data and control information through the analog
system.
To record at ~50 kHz on 128 or more channels, see PZ5 Software Control for more information.
