Note: When burning new microcode or if the firmware on the RZ5D is blank, the VFD
screen will report a cycle usage of 99% and the processor status lights will flash
red.

Important! The status lights flash when a DSP goes over the cycle usage limit, even if only for
a particular cycle. This helps identify periodic overages caused by components in time
slices.
PZ Preamplifier Port
The RZ5D acquires digitized signals from a PZ preamplifier or digital headstage
manifold over a fiber optic cable through the port labeled 'PZ' on the front panel.
This port can input up to 32 channels at a maximum sampling rate of ~50 kHz.
The PZ port can be used with any of the PZ preamplifiers including the PZ2, PZ3,
and PZ5 or the PZ4 digital headstage manifold. The PZ5_Control and
RZ5D_PZn_Input macros are used to access neurophysiological data in the processing
chain.
Important! The macro must be placed on DSP-3 in the RPvdsEx circuit. Further, when using
the RZ5D, set the
