Installing 575 System Hardware
4.14 Establishing CPU Communication
The 575 CPU has four serial communication ports and initializes all four
ports to 9600, 7 bits, odd parity, and 1 stop bit on battery-bad powerup.
These communication ports remain in this configuration unless you change
them. Port configuration can be changed using TISOFT 4.3 or later.
Figure 4-24 shows the locations of the communication ports, and the
optional PROFIBUS-DP connection.
