Overview
Abstract
CNA-1 is a network point that works as a “Protocol converter”.
It acts as an entrance to the Sony Camera Network System
(CNS).
Your system can control a Sony Camera, and can be
controlled from Sony Control Panels via CNA-1 with its
communication protocol.
How does the CNA-1 work?
CNA-1 participates in CNS as another “Sony protocol capable”
device.
It can talk to your system with a simple command protocol
(Sony Simple Camera Protocol: SSCP), providing a simple
communication mechanism for your system.
It mutually translates the protocol for a Sony Camera to SSCP.
Terminology
CNS: Sony Camera Network System
A network system consisting of Sony Cameras (Sony CCUs)
and Sony Control Panels, connected to each other via TCP/IP.
SPP: Sony Proprietary Protocol
A communication protocol used by CNS devices.
SSCP: Sony Simple Camera Protocol
A communication protocol between CNA-1 and your system.
RCP-mode, CAM-mode:
An emulation mode of CNA-1.
CNA-1 acts as a Sony Control Panel in RCP-mode.
CNA-1 acts as a Sony Camera in CAM-mode.
This configuration can be selected using the Web configurator
of CNA-1.
Application example
Sony camera control application
In this application, your system behaves as a controller for a
Sony Camera.
Your system can control a Sony Camera via CNA-1 (RCP-
mode configured) with SSCP.
Your system participates in CNS as “Sony
Camera”
In this application, your system may behave as a Camera or
other device similar to a camera.
Your system can be controlled from Sony Control Panels via
CNA-1 (CAM-mode configured) with SSCP.
