5.1Communications Ports and Modules Overview

The built-in communications and the optional communication modules provide communications between the ROC827 and a host system or external devices.

The ROC827 allows up to six communication ports. Three communication ports are built-in on the CPU. You can add up to three additional ports with communication modules. Table 5-1 displays the types of communications available for the ROC827.

Table 5-1. Built-in Communications and Optional Communication Modules

Communications	Built-in on CPU		Optional Module
EIA-232 (RS-232D) Local Operator Interface (LOI)	Local Port
Ethernet (use with DS800 Configuration Software)	Comm1
EIA-232 (RS-232C) Serial Communications	Comm2		Comm3 to Comm5
EIA-422/485 (RS-422/485) Serial Communications			Comm3 to Comm5
Modem Communications			Comm3 to Comm5
MVS Sensor Interface			Comm3 to Comm5

The communication modules consist of a communications module (card), a communications port, wiring terminal block, LEDs, and connectors to the backplane. The ROC827 unit can hold up to three communication modules in the first three module slots. Refer to Figure 5-1.
