Figure 2-17: Source Wiring for an 8-Source System
WIRING SOURCE CHANNELS IN A 15-SOURCE SYSTEM
Wiring Source-8 Connection Points to Expansion Unit 1
Figure 2-18 shows how 15-source systems must be wired. The source-expansion
pins of the main unit must be wired to expansion unit 1. Source 8 connects to
unit 1 and the source-8 connections on the main unit are left disconnected. This
wiring also applies to expansion units 2 and 3, as well as expansion units 4 and 5,
if used. Also shown in Figure 2-18 is the data-link connection between the main
unit and unit 1.
WIRING SOURCE CHANNELS IN A 48- OR 72-DESTINATION SYSTEM
Wiring Source-8 Connection Points to Expansion Units
In 48- or 72-destination systems, the wiring shown in the Figure 2-19 must be
added to join the sources of the main unit to the sources of unit 2. In
72-destination systems, this wiring must also be added between unit 2 and unit
4. Also shown in the diagram is the data-link connection between the units. Note
that the termination switches should be turned on in the main unit only, not in
unit 2 or unit 4.
In 15-source systems with 48 or 72 destinations, this wiring should also be added
between units 1, 3, and 5. Similarly, the termination switches in unit 1 should be
turned on, while the termination switches in units 3 and 5 should be turned off.
