PZ4 Digital Headstage Manifold

PZ4Overview
The PZ4 is a high channel count manifold for transmitting extracellular recordings
acquired with TDT’s ZCD digital headstages to an RZ base station for processing.
This device supports sampling rates up to ~25 kHz. The PZ4 manifold is available
with 1, 2 or 4 digital headstage connections for a variety of channel counts.
The PZ4-4 has four DB26 connections and can support up to 256 channels. The
PZ4-2 has two DB26 connections and can support up to 128 channels. The PZ4-
1 has a single DB26 connection and can support up to 32 channels.
PZ4SystemHardware
Analog signals from the electrodes are digitized on the ZCD headstage and
transmitted to the PZ4. They are then organized and streamed to the RZ base
station over a fiber optic connection for further processing and data storage.
The PZ4 Manifold has up to four 26-pin headstage connectors (DB26) on the back
of the unit. Because the PZ4 accepts digital inputs, the channel count for each
DB26 connection is not fixed. Each DB26 connection can support any headstage
channel count up to the limit for the entire PZ4 device. For example, the DB26 port
on a PZ4-1 can accept either a 16 channel (ZCD-16) or 32 channel headstage
(ZCD-32). A PZ4-2 might have a 32ch headstage (ZCD-32) connected to Bank
A and a 96 channel headstage (ZCD-96) connected to Bank B for a total of 128
channels.
The PZ4 will automatically detect the number of channels in the headstage on each
DB26. All channels will be concatenated together, starting with connector “-A-”, to
create the output signal to the RZ base station.
