Serial communication output
The oximeter is capable of two-way communication with computers:
•
Auto-output mode (default)—current data.
•
Trend-output mode—trend data stored in the oximeter's memory.
To use these modes,
•
The oximeter must be connected to the computer.
•
The computer must be running a communications program.

, pulse-rate, and PI
r
pulsatile value readings, along with a time stamp,
custom patient label, and alarm conditions, are transmitted and updated every
two seconds in auto-output mode, or every six seconds in trend-output mode. One
line of ASCII data is output to the computer every two seconds in auto-output
mode, or every six seconds in trend-output mode.
If a custom patient label was created for the data record, it appears at the start of
the data (see
LABELS in chapter 2).
The information sent to the computer screen is formatted similarly to the
following example:
