14 Nucleus Router Control Modules
The Nucleus router control modules are real-time router control cards which perform the
following functions:
•
Interface to all the external devices (control system, panels and so on), through
Ethernet and serial port connections.
•
Provides redundant control connections on RS422/485 and Ethernet.
•
Store the local configuration of the router.
•
Contain all circuitry to manage multiple reference inputs.
•
Set video and audio crosspoints in response to external commands and responds
with tally information (audio crosspoints - Nucleus2 controllers only)
•
Monitor the status of the system components and reports this to the door PC and the
external systems as required.
Up to two router controllers can be fitted to the router in a main and backup configuration.
When two controllers are fitted the controller in the left slot is the main controller and will be
active when the router is powered up. This is the default power up setting but this setting can
be changed from Workbench if required. See the Workbench manual for details. The
controller mounted in the left slot is Controller A and the controller in the right slot is
Controller B.
Note:
2464 and 2463 controllers:
•
Earlier Sirius 800 AHP routers were fitted with Nucleus2 2463 router controllers.
Now, the Nucleus2 2464 router controller is fitted to new Sirius 800 AHP routers
and is a direct replacement for the Nucleus2 2463 router controller.
•
When two controllers are fitted in the router
they must both be the same type and be running the same software version.
For example: either 2 x 2464 or 2 x 2463 or 2 x 2450 controllers should be fitted.
•
When two controllers are fitted in the router
they must both have a network connection (Ethernet A and Ethernet B);
for connection details see section 16.2, Table 85.
