Motion Sense Switch
The switch is located at the side of the adaptor and sends motion data
when the switch is in the ON position
LED Switch
The two IR LEDs on the headstage will illuminate when this switch is in
the ON position.
Impedance Switch
To select impedance mode, toggle the switch to the ON position. The
CerePlex µ headstage should not be in Impedance mode while
attempting to record neural signals. In Impedance mode, the CerePlex µ
delivers to each electrode sequentially a 1 kHz, 1 nA peak-to-peak
current for 100 ms. The CerePlex µ impedance measurements are
accurate for electrodes between 10 kOhm and 2 MOhm.
In order to measure electrode impedances with the CerePlex µ the
Central software must be configured to measure impedances using
CerePlex Family headstages. This is only required once, unless the
setting is subsequently changed. In the Central software, click on the
TOOLS drop down box then select OPTIONS. Under Auto Impedance
Interface, select “CerePlex Family”. Click OK. Next, click on the
IMPEDANCE TESTER button. Populate the dialog box that appears on
the screen if desired. Impedance values should be displayed on the
screen. To exit impedance mode, close the Impedance Tester window,
toggle the switch to OFF.
CerePlex µ Headstage Cabling
Cables are available in 1.5 ft and 2.5 ft lengths. Multiple cables can be
daisy chained to create longer cable lengths. Note that, both connectors
on the cable are keyed. Align the connectors before making connections
to avoid damage to the pins.
