Interceptors.
The combined signal, and also each individual Interceptor audio signal, can also be
routed as digitised PCM UDP data across the Ethernet network – see section 2.5.12
below.
1.4.3 Kiosk Connector
The Kiosk socket on the rear panel is a simple switch which is annunciated as a Fixed
Diagnostic circuit on the local Rack (if Fixed Diagnostic circuits are enabled). The
circuit is Secure if the switch is closed, and Tamper if the switch is open-circuit. No
configuration of this feature is possible.
1.5 System Management Using SMS Computers
Security Management Systems ("SMSs") are computers which run control software for
security and alarm systems. Comander is compatible with several SMSs, including
Cortech's Datalog, but works best in conjunction with Geoquip's own Geolog Vision
SMS.
1.5.1 Connecting and configuring a SMS computer
SMS computers can be connected to a Comander system using an Ethernet network
connection, or a COM port Serial link.
To connect using Ethernet (which is typical for the Geolog Vision SMS), simply connect
the SMS computer to the Comander Ring, and allocate a suitable IP Address and
Subnet Mask to the computer. Other configuration options must be set up in Geolog
Vision's own configuration – please see the Geolog Vision manual for details.
To connect using a Serial link (typical for Datalog or other custom SMS solutions),
connect the SMS computer to a COM port on the nearest Comander Rack unit, and
then use the Comander Rack's Configurator to configure the COM port for use as
SMS. There are three different levels of SMS access - see section 2.5.3 below for
details.
1.5.2 Using the SMS Collator
On any Comander Ring, only one Comander Rack should be configured as the SMS
Collator for the system. If the SMS computer is connected to the system via a serial
link, it is best to use the Comander which provides that serial link as the Collator.
The Collator also provides a user-friendly way of configuring multiple Geolog Vision
workstations at different locations with different user rights on the system, via the SMS
IP Connections feature.
For more information about the Collator functionality, see section 2.5.7 below.
1.6 Real-Time Clock and Time Synchronisation
Time can be synchronised across a Comander system in many ways, using multiple
timecode sources. The options described here should be implemented using the
Comander Rack's Time settings and configuration options, which are discussed in
detail in section 2.5.4.6 below.
Time synchronisation strategies usually fall into one of three categories:
SMS as Master
If the SMS is to be used as Master timecode source for the network, the SMS should
be configured to propagate its timecode to a specific Comander Rack. This Rack
should then be configured to broadcast regular timecode updates to the other Racks in
the system.
