CHAPTER 1 RCI Overview
1.3 RCI Connection Scheme
This section outlines RCI connection patterns.
• Basic configuration
Figure 1.1 shows a connection pattern with an RCI host and RCI I/O units.
Figure 1.1 Connections to RCI I/O units
RCI cables are connected in sequence to respective units using T-branch connectors.
RCI terminating resistors must be connected to the T-branch connectors at both ends
of a set of RCI connections.
Up to 32 RCIs including the RCI main unit can be connected.
Note that the maximum RCI cable length is 150 meters.
Use the repeater function of the external power controller to extend the cable length
used and to increase the number of connected RCI units.
Note: The external power controller is included in the number of RCI units.
