The host port can be configured with RS-232, RS-422, and RS-485 connections.
The following settings define the basic transmission speeds and digital standards that
ensure common formatting.
Baud Rate, Host Port
Parity, Host Port
Stop Bits, Host Port
Data Bits, Host Port
Note:
See

on page 3-23 for protocol information relating to USB.
Usage: Can be used to transfer data faster or to match host port settings.
