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.
