							11Sony Simple Camera Protocol
Types of the command
There are several types of commands and formats, depending 
on CMD-GP or combination of CMD-GP and PARAM0.
[CMD-GP]: 
Categorizes a command into “Byte type”, “Word type”, 
“Other type”, and appends a control method “Relative” or 
“Absolute”
[CMD-GP] + [PARAM0]:
Categorizes “Byte type command” into “Byte command”, 
“Bit command”, “Inc/Dec command”
Almost all commands have two different control types: 
“Relative” and “Absolute” assigned to a different CMD-GP 
(see the List of available commands)
Example: Master Black control
 Relative control: “22,a9,00,01
”  This command “adds” 
0x0001 to the current parameter
 Absolute control: “23,a9,00,01\n” This command “sets” 
0x0001 to the parameter (overwrite)
Byte command
Controls or Queries a byte-size parameter of a Camera.
Format:
 “[CMD-GP],[PARAM0],[PARAM1]
”
 PARAM0: Parameter address
 PARAM1: Value
Relative control:
It means a status query. 
PARAM1 is ignored and does not affect the status of 
the Camera.
Absolute control:
Set the parameter of Camera specified by the 
PARAM0 address to PARAM1, or a response of the 
value of the parameter from the Camera.
Bit command
Controls or Queries the ON or OFF state of a function of a 
Camera using bit (0 or 1).
Format:
 “[CMD-GP],[PARAM0],[PARAM1]
”
 PARAM0: Parameter address
 PARAM1: Value affects each bit
Relative control:
Inverts the function state specified by the PARAM0 
address ON to OFF, or OFF to ON when bit is set to 1.
If PARAM1 bits are all set to 0, it means a status 
query.
Absolute control:
Set the state at the PARAM0 address to PARAM1 or 
a response of the value of the parameter from the 
Camera.
Inc/Dec command
Increments or decrements a Camera parameter and also 
adjusts a value directory.
Format:
 “[CMD-GP],[PARAM0],[PARAM1]
”
 PARAM0: Parameter address
 PARAM1: Value
PARAM1
bit7-6: Inc/Dec control
[00] Set a value directory or status query
[01] Increment the parameter specified by the 
PARAM0 address
[10] Decrement the parameter specified by the 
PARAM0 address
[11] N/A
bit5-0: Value of the parameter
Relative control:
bit5-0 is ignored.
bit7-6 [00] or [10] or [01]: Parameter (bit5-0) query.
bit7-6 [11]: Maximum value query for the parameter 
(bit5-0).
Absolute control:
bit7-6:
[00]: Set the parameter specified by the PARAM0 
address to bit5-0.
[01]: Increment the parameter. bit5-0 is ignored.
[10]: Decrement the parameter. bit5-0 is ignored. 
[11]: Maximum value reply from a Camera. Do not 
use this bit pattern to control.
bit5-0: Value of the parameter.
Word command
Adjust a word-size parameter of a Camera, or status response 
of it.
Format:
“[CMD-GP],[PARAM0],[PARAM1],[PARAM2]
”
PARAM0: Parameter address
PARAM1-2: Value 16bit
PARAM1: Higher byte
PARAM2: Lower byte
Relative control:
PARAM1-2 [0x0000]:Parameter query.
[Others]: Add PARAM1-2 to the current 
parameter.
Absolute control:
Set the parameter to PARAM1-2.
Other command
Depends on CMD-GP, details are described in the list of 
commands.

Rules
Request and Response
Requests and response correspond loosely.
There is no one to one mapping between requests and 
responses: “No reply” means “I can’t process such a 
command”.
Do not send anything if an error has occurred. Errors must be 
handled the same as “No command”.
Responses from a Camera can be sent to your system 
anytime without a request from your system. The status of 
Camera can be changed by itself (Auto iris function, etc.), 
changed by a camera operator’s hand manually or changed by 
another control panel connected to the Camera. The Camera 
sends status changes to all connected controllers.
Your system can ignore any responses not needed by your 
system.
When to send
In the case of your system working as a controller for a 
Camera, your system should send a parameter query that it 
want to get.
Almost Sony Camera only send status when its status is 
changed by receiving commands or its function (ex. automatic 
iris control or etc.).
The status of your system can be updated by receiving status 
responses from a connected Sony Camera by sending status 
queries to that Camera (via CNA-1).
In another case, your system works as a Camera among CNS, 
your system should send commands when its status is 
changed (must behave like a Sony Camera). The commands 
must be absolute commands in this case.
If Sony control panels receive no absolute command 
responses from your system, they cannot update their status 
and also cannot update the displays.
Therefore, the absolute command responses from your 
system are necessarily for the control system.
Permission control (Panel Active control)
CNS supports operating multiple cameras by multiple control 
panels. In case of using the Panel Assign Function, control 
panels are assigned to Cameras by a CNS Master device, 
such as MSU.
The assignment function allows duplicate assignment, 
meaning one camera can be controlled by two or more control 
panels. Control conflicts can occur in this case. Therefore, 
permission control for the Camera is determined by the CNS 
Master device, using Panel Active command.
If a network system with your system requires permission 
control, your system should use Panel Active command and 
your system’s Panel Active state should be controlled by the 
CNS Master device because CNA-1 behaves in the same way 
as the Sony Control Panel in RCP-mode.
In a single connection (CNA-1 configured Bridge mode of CNS 
setting), the permission control is managed by CNA-1 itself.
Permission allows your system to send all available 
commands. Without permission, your system can send only 
Status Query commands (Control commands are rejected). 
Permission control does not regulate receiving commands.When your system receives permission using Panel Active 
command, another control panel assigned to the same 
Camera loses permission.
If your system does not want to affect the permission of 
another control panel, your system can use Para command 
instead of Panel Active command. Usage of Para command is 
the same as Panel Active command. However, permission by 
Para command does not allow controlling of Iris, Master Black 
and sending Absolute Word command.
A configuration of CNA-1 “Panel Active Function Enable/
Disable” enables this permission control function. If Panel 
Active Function is enabled, CNA-1 manages Panel Active 
state and your system can use Panel Active/ Iris Active/ Para 
commands. If the function is disabled, CNA-1 rejects these 
commands.
Permission control is not necessarily in the network system. 
Your system can ignore that and can send command if CNA-
1 configured “Panel Active Disable (default)”. However, if a 
duplicate assignment is set to CNA-1 and another control 
panel, conflict can occur between other control panels in the 
no permission control state. Especially, Absolute type 
commands will certainly conflict, and erratic Camera behavior 
can occur. For this reason, pay close attention to Absolute 
type commands
Panel active command examples:
Get current permission state
Send: “0b,90,01,00\n” => Receive: “0b,XX,01,81\n” 
XX is ID of Master device. Value “81” means sender 
(your system) has No permission
Send: “0b,90,01,00\n” => Receive: “0b,XX,01,82\n” 
XX is ID of Master device. Value “82” means sender 
(your system) has permission to control
Require the permission
Send: “0b,90,01,02\n” => Receive: “0b,XX,01,81\n” or 
“0b,XX,01,82
”
Release the permission
Send: “0b,90,01,01\n” => Receive: “0b,XX,01,81” or 
“0b,XX,01,82
”
