The Baud Rate in the Simulator must be set to match the LD.BAT Baud Rate setting as
shown in Table E-4.
Table E-4. Baud Rate Settings
LD.BAT Setting Baud Rate
30 300
60 600
12 1200
24 2400
96 9600
Note
When using the LD.BAT program to download waveform shapes, only
download one waveform shape or R-Curve file at a time. Do not string
several shapes or R-Curves into one file for download.
Player Mode
Player mode permits files of red and infrared readings, taken off an oximeter, to be
"played back" through the Simulator in real time. These are long-duration files (player
files) of real physiological behavior. These files are only available from select pulse
oximeter manufacturers. Fluke Biomedical does not supply them.
Player file data is uploaded through the Simulator’s serial port and loaded directly into
the red AC and infrared AC digital-to-analog converters (DACs). The output waves of
the DACs are controlled by the amplitude values and update rate of the serial port. Data
sampling rate and playback rate will be equal. Data will nominally be set at 9600 baud
N,8,1. However, this rate may be adjusted to control playback rate in terms of
points/second. The N,8,1 must not change.
Once a player file (named with a .BIN extenstion) is obtained, a small batch file needs to
be created and placed in the same directory (or folder). The batch file should consist of
the following commands:
•
mode com1:96,n,8,1
•
:label
•
copy /b %1 com1:
•
goto label
Note
The /b in the batch file forces DOS to handle the file as a binary file.
To use the Player Mode:
1.
Send [player] to the Simulator via computer control.
2. In DOS, go to the directory that has the two files and issue the following command:
LD filename (example: LD 8sec.bin), and press ENTER.
