Supported Network Topologies

The NJ/NX-series CPU Unit can be connected using daisy chain connections with no branching, or with
branching connections using Junction Slaves. This supports redundancy, and all topologies other than
rings. Examples of topology without branching and with branching (Junction Slaves) are shown below.
