5.1 Communication Ports and Modules Overview
The built-in communication ports and the optional communication
modules provide communications between the ROC800 and a host
system or external devices.
The ROC800 supports up to six communication ports. The CPU
provides three built-in communication ports. You can add up to three
additional ports with communication modules.
Table 5-1
displays the
types of communication options available for the ROC800.
