Networked Audio Production System
Remote Control and Production Automation
REMOTE CONTROL–CALREC SERIAL CONTROL PROTOCOL
The Calrec Serial Control Protocol
(CSCP) allows for remote control over
mixing console operational functions
by 3rd party systems such as video
switchers and production automation
systems.
Several broadcast equipment
manufacturers provide serial control
protocols that are compatible with CSCP.
The following systems are currently in
use around the world, actively controlling
Calrec audio mixing consoles for live, on-
air applications:
• Ross Overdrive (Automated Production
Control system) & Ross video
switchers.
• Sony ELC.
• Snell Kahuna.
• Mosart.
• Grass Valley Ignite.
Please refer to the manufacturer’s
guidance for specific information relating
to their products.
CSCPversions
Additional controls have been made
accessible via CSCP since it was first
introduced, requiring new commands to be
added to the protocol, and new versions
released. If 3rd party equipment receives
CSCP data it does not understand, it
should simply ignore it, however Calrec
cannot guarantee the operation of third
parties, and as such makes all CSCP
versions available for use on Summa.
FaderscontrolledbyCSCP
Third party systems with a CSCP
connection to a Summa console have
access to control and read back the status
of 192 path faders. Starting with the lowest
numbered fader (usually number 1) on layer
1, up to the highest consecutively numbered
fader, followed by the same fader numbers
on layer 2 etc. up to a total of 192 faders.
ControlsavailableviaCSCP
CSCP V1.0 allows third party controllers:
• Control over and read-back of the
position of 192 path faders.
• Read-back of the 192 faders’ path/port
labels.
• Control over and read-back of the Cut/
On status for the same 192 faders.
• Control over and read-back of the PFL
status for the same 192 faders.
• Control over and read-back of Main
output bus levels and PFL status.
• Read-back of the console’s name/ID.
CSCP V2.0 provides the same
functionality as V1.0 with the following
additional features:
• Control over and status read-back of
the same 192 faders’ routing to the
first 20 Auxiliary output buses (all 16
for Summa).
• Control over and read-back of the first 20
Aux bus output levels (all 16 for Summa).
• Read-back of the path types allocated
to the 192 faders.
CSCP V2.1 provides all the functionality
of V1.0 & V2.0 along with the following
additional features:
• Control and status read-back over the
192 faders’ routing to Main output buses.
• Control and status read-back over
‘Left to Both’ and ‘Right to Both’ input
controls for stereo paths on the same
192 faders.
Connection
Although the protocol is based on and
passes serial data, the Calrec connection
is made via TCP/IP. If you wish to
interface to third party systems that only
support point to point RS232/422 serial
connections, TCP/IP conversion will be
required. For this purpose, Calrec support
the use of, and can supply Perle IOLAN
units.
The CSCP connection should be made to
one of the RJ45 ports labelled Ethernet
1, 2 or 3*, on the front of the primary
control processor of the console to be
controlled (unlike H2O/SW-P-08/EMBER
connections, which are always made to
the Hydra2 network’s Master Router core).
If multiple consoles are to be controlled,
each will require its own CSCP connection.
*Alternatively, if your control processor
RJ45s are labelled MAC 3, 4 and 5 you
should use one of the USB ports on the
front of the primary control processor of
the console which is to be controlled—
using the D-Link USB to Ethernet adapter
which is provided with every Summa
system
Secondaryconnections
Third party CSCP controllers that support
redundant secondary connections should
be connected to RJ45/USB ports on
both the primary and secondary Calrec
controller cards to provide complete
redundancy, protecting against cable/port
failure and card removal. If required, this
connection can be via an Ethernet switch,
e.g. to allow a single RJ45 port on a 3rd
party controller to connect to both primary
and secondary Calrec ports.
Multipleconsoles
If your control processor RJ45 ports
are labelled MAC 3, 4 and 5 and CSCP
connections from multiple Calrec consoles
are to be networked together, the
consoles need to connect via a layer3 (IP)
Ethernet switch in order to prevent MAC
address conflicts.
ConnectingviaCorporateLAN
If CSCP control is to be supplied over a
corporate LAN, it is important that the IP
address of the USB to ethernet is set to
be in range of the corporate network.
