changing DIP switch settings.
There are 8 DIP switches. The top
switch is number 1 and the bottom
switch is number 8. A switch is
considered to be "ON" when the right
side is pushed down and "OFF" when
the left side is down.
As shipped from the factory, the DIP
switches are set as follows:
Switch Number

DIP Switches 1, 2 and 3: Baud Rate
Switches 1, 2 and 3 control the Baud rate used by the RS-232C Data Port. The factory
setting is for 1200 Baud. If you change the Baud rate of the P
ORTA
C
OUNT
Plus, you must
also change the Baud rate of devices that communicate with the instrument such as a
printer or computer. You should leave the Baud rate set at 1200 unless you have a good
reason to change it. The switch settings for various Baud rates are:
