Where To Go From Here
Now you are ready to program and tune your Series 1500. If you haven't read the
sample program information in Chapter 2, please do so now. Or if you already
understand how to program the Series 1500, go ahead and enter your program.
You'll find a Programming Chart in the Technical Reference section, Chapter 4, that
is particularly helpful in recording your program.
You must also set the RS-423/RS-422 Jumper for a communications interface. Put
