Glossary
Operator The term operator refers to control panel users as opposed to system configurers or system
administrators. An operator is responsible for making the routes.
Port In general, a port is a physical connection on a router. For compact machine control routers, a
port is a bidirectional serial connector. A machine control router is also called a
port router .
Remote Panel
Module A CR series product that sends take and lock messages to routers in a CR series network. The
remote panel module receives commands from an attached CR series control panel. The remote
panel module receives status messages from the routers in the network, and in turn, illuminates
its control panel buttons according to the status messages.
The remote panel module is also a place to mount a control panel.
CR6464 routers and CP6464s do not (yet) operate in conjunction with remote panel modules.
Primary level A destination’s primary level is the first level in the list of levels assigned to the destination.
Salvo A salvo is a stored group of takes that can be recalled and executed at a control panel.
Source/
Destination The term “source device” is used interchangeably with “source” and the term “destination
device” is used interchangeably with “destination.” A source is a device that is connected to one
or more input ports. A destination is a device that is connected to one or more output ports. An
example of such a device would be a monitor.
A device can be both a source and destination. An example of such a device is a VTR.
Subnet mask A 32-bit number that distinguishes the common part of an IP address from the unique part. For
two IP addresses 192.168.2.10 and 192.168.2.30, the common parts are 192.168.2 and the
unique parts are 10 and 30 respectively. The common part has 24 bits. The subnet mask in this
example is 255.255.255.0.
SWB (Super Wide Band). A term originated by Grass Valley’s NVISION business group that refers to the
ability of a router to pass a wide range of digital bit rates and formats. Grass Valley’s SWB
supports data rates from 10 Mbps to about 1.5 Gbps. The HD-SDI routers reclock at 143, 177, 270,
360, and 540MB/s and 1.483 and 1.485Gb/s. The SDI routers bypass re-clocking for non-video
rates.
Synchronous As it applies to the AES routers, “synchronous” means switched in relation to the sync obtained
from a video reference signal. The AES routers perform certain functions when in “synchronous”
mode, namely (1) outputting an AES stream at 48kHz, and (2) switching mono channels.
Take A take is a route. The panel operator “takes” a source (to a destination).
3Gig The term “3Gig” describes devices capable of operating at 2.97 Gb/s or 2.966 Gb/s
1
and lower
rates. (They reclock at 2.97 Gb/s, 2.966 Gb/s, 270 MB/s, 1.483 Gb/s,
1
and 1.485 Gb/s).
