If you are using the serial interface on the LQ, then you need to
check switches 2-3, 2-4, 2-5, and 2-6 to make sure the settings match
those on your computer.
Remember
Each time you change a DIP switch setting, you should turn
the power OFF reset the switch or switches, then turn the
power ON again. The LQ only recognizes a new setting at the
time the power is turned ON.
The following tables describe the switches and their functions. The
shaded gray boxes indicate the factory settings.
