12. Tutorials
The following topics are designed for users who are unfamiliar with routing and other aspects of
CRSC operation. Each topic covers a specific area of information:
• Networks — CRSC and related devices communicate via a network. To learn more about net-
works, IP addresses, subnets and related topics, see Creating a Network on page 8.
• Routing — An overview of how signals are moved from device to device. This section discusses
routers, crosspoints, control panels, signal types, partitions and levels, and router controls. See
Routing Overview on page 63.
• Control Panel Modes — Control panels operate in standard or enhanced mode. To learn about
how this impacts level selection by operators using the panel, see Remote Panel Operating
Modes on page 68.
• Salvos — Salvos enable you to pre-program all steps for performing a specific task so that one
button press on a control panel performs the entire operation. See Salvos on page 69.
• Cabling — Devices, such as routers and control panels, are connected using cables. This section
discusses in detail the different cables and connectors used. See Cabling on page 69.
• Products — See Products on page 77 for a list of Miranda products relevant to CRSC.
Routing Overview
Routing is the movement of signals from one device to another. In general, there are devices that
create signals, such as video recorders. These devices send the signals to a router. The router
switches the signal from the input to a designated output. Usually routers manage hundreds of
incoming and outgoing signals. The output is then sent to another device for distribution, manipula-
tion, and so on. To manage the incoming and outgoing signals, and how they are switched in the
router, operators use pre-programmed control panels. Commands from the control panels are sent
to the routers telling the routers how to switch the signals.
What is a Router?
Suppose you have two VCRs and one TV. You want to be able to view a movie from either VCR.
So you plug the cable from one VCR into the TV. When you want to use the other VCR, you switch
cables. After a while, that gets a little tiresome. Wouldn’t it be easier if you had a switch you could
flip?
Now suppose you have a dozen TVs and a dozen VCRs plus cable service. You want to be able to
direct any program from any VCR or from the cable company to any of the TVs. But how? That is
what routers do: direct the content from a number of inputs to selected outputs.
A router is a box (containing electronics) that has a number of input connectors and a number of
output connectors. Inside the box are switches that “listen” to a control panel. Pressing buttons on
