4.9.3 Ribbon Cable Connections
FIG. 4-9-3 Ribbon Cable Connection from ISA Main Unit to Axis Unit
Ribbon cables function as a communication bus between the Axis Units and the ISA Main
Unit. One cable is connected from the front of the ISA Main Controller Unit to the bottom of
the nearest mounted Axis Controller Unit. All Axis Units are then connected (daisy-chained)
with ribbon cables as shown in Figure 4-9-3. The connectors are keyed with an arrow to aid in
identifying orientation.
