Using the Front Panel Display. The front panel touch
screen display (icons shown below) can be used for
impedance testing, waveform preview, and on-the-fly
device configuration.
Open System Setup screen to access wifi
and device information.
Hardware Setup. Use the provided paired fiber optic
cable to connect the PZ5M to the RZ processor, as
shown below. The connectors are color coded and
keyed to ensure proper connections. The PZ5M-512 is
shown below. If using the PZ5M-256, connect only to
the primary connection on the RZ2 (located adjacent to
the zBUS connection).
Create a new logical amplifier. If all banks
are configured, the green plus sign is not
displayed.
Toggle LED indicators off/on.
Lock/Unlock configuration settings.
Touch the icon in the logical amp
configuration area (shown below)
to display the desired screen for the
corresponding logical amplifier.

Warning. A red outline indicates that the bank is
configured as part of a logical amplifier but no headstage
is currently detected on that bank.
Software Configuration. Logical amplifiers can be
configured on the Synapse, PZ5 options page. The table
below lists default settings for each analog input amp
type.

To test the impedance of your hardware set-up:
• Touch the icon on the desired logical
amplifier to display the Impedance Checking
screen. Swipe vertically on the interface to scroll.
Settings include:
Target. Impedance values above the target will be red,
values <75% below the target will be green and all other
values will be yellow.
Frequency. Choose the probing frequency.
Probing. Select the pins to measure. Available options
depend on the logical amp referencing mode.
Ref, GND, and AltRef values displayed on top row.
Differential: Inp[+] the positive input channels
Inp[-] the differential channels
Local: Input all input channels
Ref the reference impedance to ground
AltRef the alternative reference
Shared: Input all input channels
Ref the reference channel
Gnd the ground impedance
None: Input the input channels
Sort. Display channels with the largest variation from
the target impedance at the top of the screen.
Auto. Cycle through probing options each second.
Next. Advance to the next probing option set.

Power Status LEDs. The row of small LEDs to the
right of the battery power button report power type
and level.
The leftmost LED indicates whether the device is:
Running on mains power green
Running on battery power red
The four LEDs on the right end of the row indicate the
power level of the battery.
Power Level # of LED’s Lit
Fully charged 4
Not fully charged 3-2
Critically low, charge immediately 1
Note: The Power Switch on the back of the PZ5M must be in the ON position for the battery to charge.
