iSTAR eX Features
iSTAR eX Installation and Configuration Guide 1–3
When configuring an event, you must specify whether the event is controlled 
by the host or by an iSTAR. Software House recommends downloading the 
event to the iSTAR eX controller.
System Activity 
iSTAR eX components manage system activity in a cluster. For example, an 
input on an iSTAR eX controller can activate any output on any iSTAR eX in 
the cluster without host intervention. 
Antipassback Control 
C•CURE 800/8000 supports Global Antipassback across all iSTAR clusters. 
The C•CURE 9000 does not support Global Antipassback across all iSTAR 
clusters.
The host provides the sharing of cardholder antipassback information 
between all iSTAR clusters in the system. Antipassback decisions within a 
cluster are made by the master controller.
Diagnostic Information
iSTAR eX includes an alphanumeric LCD display that provides diagnostic 
and status messages. 
You can also view diagnostic information by:
 Using the iSTAR Web Page Diagnostic Utility.
 Using the diagnostic utilities in the iSTAR Configuration Utility (ICU).
Upgrading Firmware
iSTAR eX includes onboard flash ROM (a non-volatile memory) for storing 
iSTAR eX firmware and communications protocol parameters, such as the IP 
address and gateway router IP addresses. 
You can download firmware using either the Monitoring application or the 
ICU utility.
