The S5 UniLink Adapter is available in four models, offering a choice of two
physical interfaces for network communications: Local Line or RS-232-C
interfaces, in different voltage versions. Table 3-1 lists the model numbers,
the type of interface, and the supply voltage for each model.
Table 3-1 S5 UniLink Adapter Models

The Local Line interface to TIWAY I is a female 9-pin D connector. Two
ports are provided (see Figure 3-1) for the following purposes.
• Port 1 is the primary network port.
• Port 2 provides support for redundant media transmission when Ports
1 and 2 are connected to a redundant twisted-pair cable network.
