Command Explanation:

Where applicable, this section will provide an example of how to

create the command strings in Visual Basic. Other programming languages
may require a slightly different syntax, but the examples given should
provide enough information to port to other languages. For our examples,
we will use the default settings of the switch:

3 Character Command Sequence

Character 1 set to ASCII ESC character (Decimal 27)

Character 2 set to ASCII STX character (Decimal 2)

If you choose to use a four character command sequence, just add

another character between the second programmable character and the
command character in the command string.
