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

the jumper on W423 for RS-423, or on W422 for RS-422.
