Control concept
The communication between the BRC 8 Remote Controller, and the C8k frame, is based on the CAN bus.
Up to 8 panels may be connected in a daisy chain to control one frame. It is not possible to control multiple
frames with one panel.
GPI/Os of a c8k system are transmitted over the CAN bus independent from the type of module or from a
GPI/O device. I.e. the C8817 physical GPI/O module behaves the same way as the
BRC 8 Remote Controller. A physical GPI may be given a virtual number from 1 to 127. Virtual GPOs also
may have a number from 1 – 127. Such virtual numbers must be mapped to physical interfaces. GPIs and
GPOs do not "see" each other on the CAN bus. I.e. you can not control a module by the GPO of another
module! In this case you must use the GPI/O conversion function of the C8817 GPI/O module.
The BRC 8 Remote Controller has 8 operating buttons. Each button may issue a virtual GPI number
and a virtual GPO my be mapped to the tally lights of that button.
As an extra feature of the BRC 8 Remote Controller allows to control the GAIN(s) of audio channels of
selected modules. Depending on the audio channel setup this could be done for linked channels
(e.g. for the surround channels of a 5.1 program) or for grouped channels (independent channels will be
grouped for gang style gain setting).
Getting started – CAN bus setup
The BRC 8 Remote Controller must be connected via a twisted pair cable. This can easily be done by using
one pair of the Ethernet (e.g. CAT5) infrastructure of a facility including patch panels.
Maximum cable length is 300m.
Important Note! The CAN interface must not be connected to active Ethernet components like hubs, routers
or switches. This may damage one or both sides of the components of network equipment or the
BRC 8 Remote Controller itself.
The pin out of the RJ45 connectors at rear allows a 1:1 connection with the RJ45 CAN socket at the front
panel of the frame controller C8702.
It is mandatory that the CAN bus is terminated at both ends. A c8k frame has a built in CAN termination on
the back plane and either the frame controller or the sync module has the second one activated by a DIP
switch. If a BRC 8 Remote Controller will be connected to the frame one must turn CAN Term switch off at
the frame controller (if no sync module is installed) or at the sync module. See respective manuals for details.
Now the TERM switch at rear of the BRC 8 Remote Controller must be switched ON.
If multiple BRC 8 Remote Controllers are installed in a daisy chain only the TERM switch of the fare most
panel must be ON.
Getting started – Power up
If you turn power on the following sequence will appear in the display:
