Identifying Your Controller
The following figure illustrates the position of the
controller's basic parts, such as:
• The communications jumpers, which are set to RS-232
mode by default. If you plan on using RS-422 mode,
you must move the shorting jumpers.
• The S1 switch, which sets the I/O address. The S2
switch, which sets the interrupt for the controller.
• The Out and In headers for daisy-chaining multiple
controllers.
S1 (ADDRESS)
S2 (INTERRUPT)
