The message “Pulse sensor not found. Please make sure sensor
is connected to the serial port on your computer.” appears when
you want to select one of the Training Modes.
Make sure that the sensor is plugged in to the serial port on the back
of your computer. Then select Exit from the File menu and restart
the Freeze-Framer software by double clicking on the Freeze-Framer
program icon on your desktop.
If you have two serial ports, one with a serial port mouse and the
other with the nger sensor - shut down and power off the computer.
Switch the nger sensor and mouse connectors on the back of the
computer. Restart the computer. Run the Freeze-Framer to see if
the nger sensor is found. Another approach would be to install a
PS/2 mouse in place of the serial mouse, if your computer has a PS/2
mouse port on the back of the computer.
If you have software loaded that connects to external devices that
connect via the serial port—like the Palm Pilot, a Windows CE device
(see below), another computer (e. g., IntelliSync or LapLink) or de-
vices like a digital camera, you will need to disable the software that
accesses these devices before starting the Freeze-Framer software.
Re-enable the software and reconnect the other device when you
want to use the other device.
Another way to check to see what programs could be utilizing the
serial port is to look at the list of programs that automatically start
when you boot your computer. Click on the “Start” button in the
lower left corner of your desktop. Move the mouse to “All Programs”
tab if necessary. Click on the “Advanced” button. Click on the “+” to
the left of “Programs.” Click on the “StartUp” item in the list. Exam-
ine the list to the right. See if any of the programs listed would utilize
the serial port. If you no longer use any of these items, drag the icon
to the desktop to remove it from the list. This way you can put the
icon back if you need to. Later, you can put it in the Trash after you
are certain you no longer need it.
