See Appendix D for details on connecting each terminal. See
Chapters 5 through 14 for details on using a terminal to configure the
decoder and to monitor operations.
The HOST port allows the exchange of data between a host
computer and the decoder. A host computer can configure the
decoder, remotely control the decoder, receive messages and data
from the decoder, and exchange messages with the AUX terminal.
The HOST port on the NEMA Type 1 decoder is configured as
shown below, and communicates over an RS-232, RS-422, or
RS-485 communication line. It has a 25-pin (female) D shell
connector. Figure 4.9 shows host devices you can connect to the
HOST port of the NEMA Type 1 decoder.
