Port Configuration
The 232PE has four selectable ports labeled "A" through "D".
Refer to Figure 8. Any of the ports can be manufactured to meet
either RS-232 or RS-422/485 electrical characteristics.
RS-232 Configuration
RS-232 ports will be wired as DTE ports. Refer to Table 2 for
pin out, signal name, and signal direction information. Also, refer to
