System 3
The following table provides a quick overview of the amplifier and analog I/O
features and how they must be accessed during circuit design. When the
RZ5_AmpIn_MC and RZ5_AmpIn macros are not used, reference the table and be
sure to use the appropriate component, channel offset, scale factor and so forth.

Onboard Analog I/O
The RZ5 is equipped with four channels of 16-bit PCM D/A and four channels of
16-bit PCM A/D. All 8 channels can be accessed via front panel BNCs marked A
and DAC or via a 25-pin analog I/O connector. See "RZ5 Technical Specifications"
on page 1-59 for the DB25 pinout.
Fiber Optic Preamplifier Ports
The RZ5 acquires digitized signals from a Medusa preamplifier over a fiber optic
cable. This provides loss-less signal acquisition between the amplifier(s) and the
base station. Two fiber optic ports are provided to support simultaneous acquisition
from up to two preamplifiers. Each port can input up to 16 channels at a maximum
sampling rate of ~25 kHz.
The fiber optic ports can be used with any of the Medusa preamplifiers including the
RA16PA, RA4PA, or RA8GA. The channel numbers for each port begin at a fixed
offset regardless of the number of channels available on the connected device.
Channels are numbered as follows:
Amp-A
Amp-B
Note: When using the RZ5_AmpIn_MC and RZ5_AmpIn macros, the necessary scale factors
and channel offsets for configuring the fiber optic ports are automatically applied.
