How can people with small ngers use the nger sensor?
Insert a cotton ball or a small piece of foam between the black nger
sensor strap and the nger. You can turn the nger sensor around so
that the cord is pointed toward you, so that the tip of the nger more
easily reaches the sensor window.
The connector on the Freeze-Framer nger sensor doesn’t match
the serial port connector on my computer.
Some older PC serial ports (COM ports) have a DB25 connector. In
this case, you will need a DB25 female -DB9 male adapter, which
is available from most computer stores for a few dollars. If this is a
second serial port, you may have to enable it at the BIOS level of
your computer, otherwise you’ll get a “Pulse sensor not found” mes-
sage when you run the Freeze-Framer program. Follow the instruc-
tions included with your hardware for changing BIOS settings. Your
computer may not have a serial port. There is an external monitor
connector on laptops that is the same size as the nger sensor con-
nector, but which has 15 instead of 9 pins.
How can I determine what serial ports are active on my com-
To see the status of the serial ports, right-click on My Computer,
and choose Properties from the menu. Click on the Hardware tab
of the System Properties window, then the Device Manager button.
Click on the Ports (COM & LPT) to see what COM ports exist. If a
small yellow or red graphic is present on a COM port, a problem or
con ict may exist that will have to be xed before the Freeze-Framer
program can read data from the nger sensor.
My PC has a mouse connected to the serial port. What can I do?
You have a number of options. 1.) See if your PC has a small round
port that you can connect a PS/2 mouse to. Substituting a PS/2
mouse for the serial mouse would free up the serial port for the nger
sensor. 2.) Consider installing a serial/parallel port card, which would
give you an additional serial port for the nger sensor. 3.) If your PC
