DPM CPL Interface
DPM CPL Interface
This section covers configuration of Control Point Language (CPL) control
of external DPM devices. CPL control is only available from two serial
ports (CPL 1/J8 and CPL 2/J9) on the rear of the Zodiak Video Processor
frame.
Devices such as Grass Valley Group GVEous and Krystal DPMs offer the
highest performance when configured to a Zodiak system via CPL. Inter-
facing to both GVeous and Krystal devices is detailed in this section.
Control of these devices is also possible through Peripheral Bus II and GPI
interfaces as explained in their respective sections of this appendix.
GVeous Digital Effects CPL Interface
This section covers CPL control of a GVeous system. Also refer to the
GVeous documentation set for additional information not given here.
CPL Interface Functionality
The following interface functions are supported:
•
GVeous effect recall via E-MEM,
•
CPL effect run control,
•
GVeous control of Zodiak Aux buses for source selection (keyframable),
and
•
Effects Send.
GVeous Requirements
The GVeous system must be equipped with the CPL Protocol Converter
module.
Control Interface Cabling
Connect serial port
CPL 1/J8
or
CPL 2/J9
on the rear of the Zodiak Video Pro-
cessor frame to the
HDLC
port on the GVeous frame using a standard 9-pin
RS-422 machine control cable. Also connect the GVeous CPL module to the
GVeous
Aux
or
Editor
port, using a custom serial cable provided with
GVeous. This cable is similar to an RS-422 cable except that pins two and
seven are cross-wired and one connector is 25-pin. HDLC may need to be
reset.
