(13) INPUT
To connect to the MED probe, through the MED-CO3 connector, to the amplifier.
(14) OUTPUT(1-32CH)
To connect the output of channels 1-32 to the to the first A/D board in the computer.
(15) OUTPUT(33-64CH)
To connect the output of channels 33-64 to the to the second A/D board in the computer.
(16) SIGNAL OUTPUT
BNC connectors used to send analog outputs from selected recording channels to an external amplifier, signal
processor, or other device (e.g. - oscilloscope).
(17) STIMULUS EXT 1
To connect to an external stimulus isolation unit. Outputs the EXT 1 trigger pulse from the computer to the exter-
nal stimulator.
(18) STIMULUS EXT 2
To connect to an external stimulus isolation unit. Outputs the EXT 2 trigger pulse from the computer to the exter-
nal stimulator.
(19) OPERATION IN
A port of input trigger signals from the external components.
(20) OPERATION OUT
A port of output trigger signals to the external components.
(21) SIGNAL GND
A ground terminal for signals.
(22) ~ AC IN
Insert the AC power supply cord here.
Reference Electrodes
To optimize the signals from all 64 electrodes as recording/stimulating electrodes, reference electrodes
have been added. This allows differential recording to be made between each channel and reference
electrodes. It also optimizes the delivery of mono-polar stimuli, as they are delivered between the chosen
(recording) electrode and the reference electrodes.
