to 16 channels at a maximum sampling rate of 25 kHz. The Legacy fiber optic ports
can be used with any of the Medusa preamplifiers including, the RA16PA, the
RA4PA, or the RA8GA. The channel numbers for each port begin at a fixed offset
regardless of the number of channels available on the connected device.
Digital I/O
The digital I/O ports include 24 bits of programmable I/O. The digital I/O is divided
into three ports (A, B, and C) as described in the chart below. All digital I/O lines
are accessed via the 25-pin connector on the front of the RZ2 and ports A and C
are available through BNC connectors on the front panel.
Digital I/O
See "RZ2 Technical Specifications" on page 1-14, for the DB25 pinout and BNC
channel mapping.
See the "Digital I/O Circuit Design" section of the
information on programming the digital I/O.

The data direction for the Digital I/O is configured using the RZ2_Control macro in
RPvdsEx.
Double-click the macro to access the settings on the Digital I/O tab. The
RZ2_Control macro also offers a Direction Control Mode parameter that enables the
macro inputs and allows the user to control data direction dynamically. For more
information on using the RZ2_Control macro see the help provided in the macro's
properties dialog box.
