The event output can be stopped at any time by again pressing
the EVENT button. To restart the output, push the EVENT
button again—if fewer than 30 seconds have elapsed, the
output continues from the point at which it was stopped; if
more than 30 seconds have elapsed, the output starts again at
the beginning. While the event output is stopped, there is a
zero-voltage output signal.
Do not attempt to print event data on a NELLCOR N-9000
recorder/interface.
Sending Trend and Event Data to ASCII Devices: Trend
and event data collected by the N-200 is available to ASCII
devices through the SERIAL COMM connector. See Connecting
to Other Instruments section for more information on trend and
event data and RS-232 formats.
To Stop an Ongoing Output of Trend or Event Memories:
press and hold both TREND and EVENT buttons (End Prt
appears); while continuing to press and hold the buttons, turn
the control knob clockwise until Prt End flashes. Release the
buttons; Prt End lights steadily and the output is canceled.
