SIMPLE SENSOR CONNECTORS
Regardless of the type of device connected, every sensor or I/O device connects to the MP35/30 using
a “Simple Sensor” connector. Simple Sensor connectors are designed to plugs only one way into the
MP35/30, so you don’t have to worry about plugging things in upside down or into the wrong socket.
•
Electrodes, transducers, and the pushbutton switch all connect to the channel input ports on
the front panel of the MP35/30.
•
Headphones and the stimulator connect to the “Analog out” port on the back panel of the
MP35/30.
•
MP35 only: A digital device may connect to the “I/O Port” on the back panel
•
MP35 only: A trigger device may be connected to the “Trigger” port on the back panel.
FRONT PANEL
Front Panel, MP35
The front panel of the MP35/30 has an electrode check port, four analog input ports, and two status
indicators.
Electrode Check
•
The Electrode Check port is a diagnostic tool used with the BSL
PRO
software to
determine if the electrodes are properly attached to the subject. See page
Input ports: CH 1, CH 2, CH 3, and CH 4
•
The inputs on the MP35/30 acquisition unit are referred to as Channels. There are four 9-
pin female analog input ports on the front of the MP35/30. The Biopac Student Lab Lessons
software will always check to see that you have the proper sensors connected to the
appropriate channel.
Status indicators
•
The Busy status indicator is activated when the MP35/30 is acquiring data and also during the
first few seconds after the MP35/30 is powered on to indicate that a self-test is in progress.
(When the MP35/30 passes the power-on test, the Busy light will turn off.)
•
The Power status indicator is illuminated when the MP35/30 is turned on.
