Introduction
Hardware Summary
A CRSC network has the same topology as a stand-alone network (shown in Figure 1-1), except
(1) the routers and remote panel modules have been configured under CRSC which provides a
more elegant solution to system design than does a stand-alone network.
NV9000 Networks
Figure 1-2 shows a sample NV9000 network, one of several possible topologies:
Fig. 1-2: NV9000 Network of Routers
An NV9000 network supports a larger number of routers. Commands issue from the remote
panels to the NV9000 which then dispatches the instructions to the routers. The routers return
status to the NV9000 which in turn relays the status to the remote panels.
CR Series routers can be used with a NV9000 family router control system. These router control
systems extend the capabilities of the compact routers.
An NV9000 network is constructed and operated according to the requirements of the NV9000
router control system. Configuration and control of the routers is entirely within the scope of
NV9000-SE Utilities, although you can use CRSC to designate IP addresses.
CQX Networks
Figure 1-3 shows the ways a “clean and quiet” router can be connected:
Fig. 1-3: CQX Network
At present, the CQX connections are limited. One CQX router with a local (or captive) CQX panel
or a remote CQX panel (or both) can exist on any subnet. (You can have more than one subnet,
however.)
At present there is little to configure other than the IP address of the router (and possibly the
remote panel module).
