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.

Device No. Configuration for CNA-1
In this case, Device number of CNA-1 must be set to different number from RCPs connected to the network. CNA-1 will be 
recognized as one of RCP and CNA-1’s Device number is handled as RCP number in CNS.
In default setting of RCP assignment, RCP can control CCU (and camera) which has same number from RCP number. 
Ex.  RCP No. (1) can control CCU No. (1)
CNA-1 (1)-(3) has Device number (4)-(6). In this setting, CNA-1 cannot control any CCU (and camera) (4)-(6) because CCU (4)-
(6) is not connected in this network.
For control (1)-(3) camera by CNA-1 (1)-(3), CNA-1 must be assigned to CCU (and camera) (1)-(3) by RCP assignment function 
provided from MSU. MSU will find CNA-1 as RCP (4)-(6).
For detail of RCP assignment function, see MSUs Operation Manual.

Notes on using USB flash drive
 Do not operate CNA-1 with USB flash drive.
USB flash drive is development use only.
Log processing with USB flash drive may interfere with 
CNA-1s SSCP connection if an inserted USB flash drive 
has some malfunction or does not have enough capability 
of data writing speed. 
 Sony USB flash drive USM*GLX series are recommended.
USB drives other than those recommended may not be 
recognized when connected to the USB connector.
USB drives must be formatted with the FAT16 or FAT32 
file system. Recommended Sony USB drives are 
preformatted, and can be used without any prior setup. 
						

							9Sony Simple Camera Protocol
Sony Simple Camera 
Protocol
Introduction
Overview
Sony Simple Camera Protocol (SSCP) is a communication 
protocol between your system and CNA-1. It is an ASCII 
character based protocol via TCP/IP. The port number of TCP 
is configurable.
It has no complex mechanism such as Application-level 
session control, Keep-alive, Device identification or 
Authentication. Therefore, your system can control Sony 
Cameras, or can be controlled from Sony Control Panels, 
using just send/receive command(s) without any complex 
procedure.
Overall operation
Basically, CNA-1 listens to a specified TCP port and awaits a 
connection from your system. When a connection is 
established, CNA-1 is ready to send and receive control 
commands immediately.
The connection behavior varies based on its emulation mode. 
(See connection section.)
Specification
Network
Link layer:
Ethernet, 100BASE-TX
Network layer:
IPv4
Transport Layer:
TCP
Port number is configurable other than 7700 (CNA-1 
reserved) or well known ports (1-1023)
Data structure
Packet:
Variable length depends on MTU configuration.
MTU value of CNA-1 is 1500 bytes. It is preferred that 
MTU of your system is configured less than 1500. 
Data:
ASCII character codes:
 Available ASCII printable characters:
– Lower alpha: “a” .. “z”
– Higher alpha: “A” .. “Z”
– Digit: “0” .. “9”
– Others: “,” (comma)
 Available ASCII control characters:
– New line: “
”, “
”
Note
If a packet includes unavailable characters or bytes, it is 
handled as an invalid packet and discarded.
Command
A command is described by Hexadecimal data assembled by 
ASCII characters above.
Lower and upper case alphabetical/numeric:
2 characters requires 1 byte
Comma:
Delimiter of each byte
New line:
Termination of a command, “
”, “
” and “

” are 
available.
Example: (Set Master Black to 0):
“23,a9,00,00
”
Constructing a command by multi-packet is possible.
Example:
“23,” Packet1
“a9” Packet2
“,00,00” Packet3
“\n” Packet4
CNA-1 will concatenate packets (1-4) and recognize that 
as “23,a9,00,00
”.
Multiple commands in a packet is possible.
Example (Set White Balance R-ch, G-ch, B-ch to 0 at the 
same time):
“23,01,00,00
23,02,00,00\n23,03,00,00
” 
Important limitation
Maximum command length: 160 byte (characters) / packet
If CNA-1 cannot find the terminator (New line) after it 
receives 160 bytes, it will discard the received data.
Minimum inter-packet (including complete command(s)) 
interval: 50 msec
This limitation is important to avoid Camera malfunctions. 
An overly short inter-packet gap can impose a heavy load 
on a Camera’s processor, and interfere with its 
processing. It is possible that unexpected Camera errors 
might occur.
If your system needs to send a number of commands, the 
commands must be concatenated and put in a packet.
In an application including periodic scan for Camera 
status, it is recommended that the inter-packet-interval is 
set to as long as possible, for effective Camera operation.
Terminator:
CNA-1 only sends “
” as terminator even if it receives “
” 
and “

”.
Connection
CNA-1 configured for RCP mode
1 CNA-1 searches for a Sony Camera or Sony CCU by CNS 
configuration.
2 When CNA-1 connects to that, CNA-1 listens to specified 
TCP port and awaits a connection from your system.
3 Your system ready to connect to CNA-1
Note
If CNA-1 loses its CNS connection (to Camera or CCU), it 
terminates the connection with your system, and returns to (1). 
						

							10Sony Simple Camera Protocol
CNA-1 configured for CAM mode
1 After booting CNA-1, it listens to the specified TCP port, 
and awaits connection from your system immediately.
2 Your system connects to CNA-1.
3 When connection is established, CNA-1 searches a CNS 
by its configuration and participate in CNS as one of a 
Sony Camera.
Note
If CNA-1 loses connection with your system, it closes the 
session to CNS, and returns to (1).
