Connecting to the Host
iSTAR eX Installation and Configuration Guide 4–7
Connecting to the Host
You can connect the iSTAR eX to the host using:
 Network connections – connect to the Onboard 1 (10/100Base-T) port or the 
Onboard 2 (10/100Base-T) port. 
Primary and Secondary Connections
One iSTAR eX controller is always designated as master, and provides the 
primary communication path to the host. A secondary path can be configured 
on the same master or on an alternate master. 
This section provides instructions for connecting the iSTAR eX to the host. For 
the list of primary and secondary configurations recommended by Software 
House, see Table 2.1 on page 2-8. 
Connecting to the Host via the Network 
To connect to a 10/100Base-T network
1. Route the Ethernet wiring into the controller through the closest 
knockout/conduit to the port.
2. Plug the RJ-45 connector into the port on the iSTAR eX GCM, as shown in 
Figure 4.3.
