1-54 System 3
RZ5 BioAmp Processor
LED will be lit dim green if the cycle usage on a DSP is 0%. If the demands on
a DSP exceed 99% of its capacity on any given cycle, the corresponding LED will
flash red (~1 time per second).
Front Panel VFD Screen
The front panel VFD screen reports detailed information about the status of the
system. The display includes two lines. The top line reports the system mode, Run!,
Idle, or Reset, and displays heading labels for the second line. The second line
reports the user’s choice of status indicators for each DSP followed by an aggregate
value.
The user can cycle through the various status indicators using the Mode button to
the bottom right of the display. Push and release the button to change the display
or push and hold the button for one second then release to automatically cycle
through each of the display options. The VFD screen may also report system status
such as booting status (Reset).
Note: When burning new microcode or if the firmware on the RZ5 is blank, the VFD
screen will report a cycle usage of 99% and the processor status lights will flash
red.
Status Indicators Description
Cyc: cycle usage ( note: limited to 2 digits; ex: 110 displayed as
10)
Bus%: percentage of internal device's bus capacity used
I/O%: percentage of data transfer capacity used
Opt: Connection (sync) status of amplifiers A and B
Important! 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.
Amplifier and Onboard Analog I/O
The RZ5 is equipped with both amplifier input and onboard analog I/O capabilities.
The fiber optic ports allow a direct connection to Medusa Preamplifiers. Physiological
signals are digitized on the preamplifier and transferred across noiseless fiber optics.
The RZ5_AmpIn_MC and RZ5_AmpIn macros automatically apply the necessary scale
factors and channel offsets for configuring the preamplifier fiber optic ports.
