DIP switches are for assigning an address to the RAX-LCD.
Binary addresses 33 to 63 are available with the least
significant bit being switch SW-1 and the most significant bit
being SW-6. The OFF setting is active binary. DIP switches
SW1-7 and SW1-8 are not used. For example, address 33 is
set by setting SW1-6 and SW1-1 OFF and all the other DIP
switches are ON.
SW1-6 = Address A5(OFF)
SW1-7 = not used
SW1-8 =
