System 3 6-53
PZ5M Medically Isolated NeuroDigitizer
PZ5M Technical Specifications
*Note: If recording at ~50 kHz on 128 channels, see “PZ5M Software Control” on
page 6-36, for more information.
Input Connectors
PZ5M NeuroDigitizers has up to eight headstage connectors on the back of the unit.
Each connector carries input signals and some combination of ground(s) and
reference(s).
Pinout Diagrams
The PZ5M connectors are labeled alphabetically from right to left. The corresponding
channel numbers depend on 1) the reference mode configuration and 2) the position
of the bank in a logical amplifier.
For simplicity sake, the diagrams below assume channels for that connector begin
with channel 1. For example, in the first pinout below A1 – A32 represent the first
