Customize As Required
Your system is now ready to customize for best performance in your
particular application. The software screens used to do that have
been structured to “walk you through” the configuration process. We
recommend stepping through the screens in the order they appear,
using this manual as a reference.
If your application requires a host device or I/O modules, the next
two sections, “Connecting Host Device” and “Installing I/O
Modules” will help guide you through the hardware configuration
required to use them.
The AUX port supports a terminal for either configuring the decoder
or for manual data entry.
The AUX port on the NEMA Type 1 decoder is configured as shown
below, and communicates over an RS-232 serial communication line.
It has a 25-pin D shell (female) connector. Figure 4.7 shows
terminals you can connect to the AUX port of the NEMA Type 1
decoder.
