Changing the Baud Rate
The RS-232 protocol factory setting is 9600 baud, 8-bits, no
parity, 1 start bit and 1 stop bit. The position of internal rotary
switch SW3 on the main controller board controls the baud
rate and parity. To change the switch setting, remove the four
screws from the top of the case and lift the cover straight up.
Locate SW3 (see drawing below) and use a small, flat blade
screwdriver to rotate the switch to the desired position. SW3
switch positions are defined in the table below.
