Uploading Firmware
You will receive a firmware file when your receive CRSC. You can receive firmware updates peri-
odically or upon request.
We recommend that when you receive a firmware file, you upload the firmware to all your
compact routers and remote panel modules before proceeding. See
How to Update Firmware
on page 95.
Panels Locked at Reset
After a reset, a panel is locked. Before you can use a panel, you must unlock the panel by
pressing the red ‘Panel Lock’ button.
System Design
By the time you are ready to use CRSC, most of the compact router system design decisions
have likely already been made. However, it may be helpful to review the following points to
ensure that all issues have been captured in your system design.
Design Issues
What signals does you system manage? How many signals are there?
What are the signal types? Do you need or have machine control routers?
Are you using CQX (“clean and quiet”) routers? If so, CQX routers only operate by themselves
with CQX control panels and must be on a separate subnet from other routers.
The CR6400 routers have an architecture that differs slightly from the architecture of the other
CR Series routers. Be aware of those differences. Please refer to the CR6400 Family User’s Guide.
A compact router has a maximum of 16, 32, or 64 inputs or outputs. (An AES router in mono
mode has a 64×64 matrix although it is still considered a 32×32 router.) How you partition a
router depends in part on the organization of buttons on your control panels and similarly the
organization of buttons depends in part on router partitions.
Router partitions are contiguous sets of connectors in the ordering of connectors on the router.
A partition cannot consist of a disjoint set of connectors.
Router partitions may overlap if it suits your system design.
Router partitions, especially for AES or machine control routers, depend on many factors:
AES partitions — number of AES channels. Number of embedded audio channels.
Machine control partitions — what kind of devices you have that require machine control.
HD routers can switch SD signals. You do not need a separate SD router. If you have a 3Gig
router, it can switch HD and SD signals as well as 3Gig signals.
You can switch analog signals using analog video (AV) and analog audio (AA) routers. You can
also use analog-to-digital (A/D) and digital-to-analog (D/A) converters in conjunction with HD,
SD, and AES routers when you have analog signals. Whether this is an effective solution depends
on factors that include your budget, whether you need or already have A/D and D/A converters,
and how much delay you can tolerate in your video or audio.
Whether your video signals contain embedded audio is another issue. Do you actually need any
audio routers?
