Please note:. Each page number in the index is a hyperlink. Double quotation marks enclose informal or colloquial expressions. If a distinction is required, it will be made. They are not configurable and do not have the capabilities of remote panels, but are useful for some purposes.

Most buttons assume a low tally state until selected. The CP a 1RU panel is special case not listed in the tables above: it controls 32 sources and 1 destination. See page An input can be routed to any or all of the outputs. The machine control routers also called port routers are point-to-point routers.

An input can be connected to at most one output. The connections are RS and bidirectional, typically with commands in one direction and responses in the other direction. For the clean and quiet outputs, the router performs smooth transitions. The transitions are governed by transition type and transition rate, selectable on the CPCQX control panel. The CQX routers also provide 2 bypass inputs. The 2 clean and quiet outputs switch to the bypass inputs if the router loses power.

There are no 2RU clean and quiet routers at present. The inputs each select one of the video inputs for CQ output 1 and the outputs signal alarms and status. The family includes two routers and a control panel. The CR routers have removable control cards, removable crosspoint cards, and a removable fan tray.

Because they are removable, they are field-serviceable. If a router is populated with one or more 3Gig cards, it is considered a CRGig. The CR family products work together may be mixed on the same subnet with other CR Series routers and panels. A CR Series control panel mounts on the front of a router or on the front of a remote panel module and provides direct visual and tactile control of the router or routers connected to the remote panel module.

You can install or uninstall one easily in a few seconds. However, any of. The CP is special case: it is a 1 RU panel that controls 32 sources and 1 destination. A remote panel module receives take and lock commands from an attached control panel and must have a control panel attached to be useful.

A remote panel module can be configured to operate with its mounted control panel as either. See CRSC on page 45 for information. Here, the panels and routers are configured using CRSC. A remote panel is one mounted on a remote panel module. Routers and remote panel modules come from the factory ready for stand-alone operation.

Once configured, they must be reset if they are to work in stand-alone mode. These configuration modes are not compatible. Figure compares a stand-alone router with a captive panel to a stand-alone router network with remote panel modules:. An NV network supports a larger number of routers.

Commands issue from the remote panels to the NV which then dispatches the instructions to the routers. The routers return status to the NV which in turn relays the status to the remote panels.

CR Series routers can be used with an NV router control system. The NV system extends the capabilities of the compact routers. An NV network is constructed and operated according to the requirements of the NV router control system. At present, the CQX connections are limited. 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.

Figure compares a stand-alone CR router with a captive panel to a stand-alone router network with remote panel modules:. The routers are slim 35—57mm or 1. The fronts of all the 1RU routers are the same except for their legends and the fronts of all the 2RU routers are the same except for their legends. The analog audio routers have DB25 connectors and fans. The machine control routers have RJ connectors.

Some routers e. All compact routers save their state in non-volatile memory. Thus, if a power loss occurs, a router can recover almost instantly. All compact routers require a few seconds to initialize. All compact routers, including CR routers, but not machine control routers, accept these video reference rates:. The video routers perform input equalization and, except for the -NR models, perform reclocking of outputs.

The -NR models do not perform reclocking. Router outputs are switched in sync with an external video reference if it is present. The 3Gig routers bypass re-clocking for other rates.

Video references must be nominally mV p-p and bi-level or tri-level in nature. These models are less expensive than the models that have reclocking circuitry and work well with relatively noise-free signals. The reclocking models give better performance in noisy environments. The digital video routers other than CQX routers perform video processing for these rates:. The HD routers can also receive video at SD rates.

The CQX routers have two crosspoint matrices. The first crosspoint routes 16 normal inputs either to an internal mixer or to the second crosspoint matrix.

The mixer has 2 channels. One of the inputs is the signal previously routed to that channel and the other input is the signal that will be routed to that channel. The mixer produces the transition between the previous input and the next input according to the transition type and transition rate currently selected at a control panel for the router.

The mixer transitions both the video and the audio without artifacts. The mixer transitions signals of level A, at p, video and audio without artifacts. It handles level B—two i signals in one stream —somewhat differently. Although audio for Link B is not processed and undergoes a cut transition, video for Link B is mixed according to the transition type and rate selected on the CQX control panel.

The second crosspoint matrix receives internal signals and produces the CQX outputs 1 and 2 and the 6 auxiliary outputs which are normal outputs. A multiplexer selects either the clean output or the emergency bypass input. The emergency bypass input is selected only when power fails. The multiplexer is controlled by a relay that switches to its relaxed position when power fails.

The video routers perform input equalization and perform reclocking of outputs. The video reference also provides sync for embedded audio. The CQX video routers also provide a bypass path for non-synchronous input signals. Thus, the clean and quiet output behaves like an aux output in which there is no video or audio processing—with no transition processing. However, if there is no video reference present, the CQX does the cut to the new source as soon as it receives the command from the control panel and does not wait for the switchpoint.

Where one or both of the sources is off-rate or at a frame rate different from that of the video reference, the output will bypass the video processor. If a clean and quiet output is in a non-sync state but conditions change so that a clean switch is possible, the processor waits for one frame of video before switching to processed video to ensure that the processed video has enough time to pass through the video processing path.

The CQX video routers have a removable fan unit. The fan unit is not visible when a CQX panel is mounted on the router. Both are position rotary switches that turn with a small screwdriver.

See CQX Routers on page 81 for details. As stated above, you can assign each node a respective role as master , data node, ingest node, coordinating node.. In this setup, we will configure all the three nodes to act as both master and data node. There are two important discovery and cluster formation settings that should be configured before going to production so that nodes in the cluster can discover each other and elect a master node;.

Each value has the format host:port or host , where port defaults to the setting transport. This setting was previously known as discovery. Configure this setting on all Nodes as follows;. Pass an initial list of hosts to perform discovery when this node is started:. Bootstrap the cluster using an initial set of master-eligible nodes:. Elasticsearch sets the heap size to 1GB by default. Open below file and add vm.

You can check the Elasticsearch status running the command below;.
