NOTE:

Never route these messages through Sony cameras. They are provided for debugging on

the PrecisionHD cameras only, and do not conform to the Visca length requirements.

Command set

Command packet

Comments

SW start

8x 01 50 a2 0p 0q

0r 0s 0t 0u 0v 0w ff

pqrstuvw = size, pq=LSB Returns y050ff if

ok.
Fatal errors: Returns y06006ff if upload

already in progress. Returns y06007ff if

unable to access the flash.

SW end

8x 01 50 a1 ff

Sent after last SW packet, instructs camera

to verify new application. Command may take

up to 30 seconds to complete.
Returns y050ff if ok. Issue a camera reboot

to activate new software.
Returns y06008ff if verification of sw failed.

SW abort

8x 01 50 a3 ff

Abort sw upload in progress

SW packet

8x a0 pp qq rr ss

[256 bytes data]

ppqq = 16 bit packet id, pp=LSB

rrss = 16 bit CRC, rr=LSB
Returns y0 50 ff if packet ok.

-> send next one.
Returns y0 60 09 ff if crc error -> retransmit

packet.
Returns y0 60 0a ff if id error

-> retransmit packet
Fatal errors:

y0 60 0b ff not in upload mode

y0 60 0c ff error writing data to flash
NOTE: Entire message after 8x a0... is raw

data, so it may contain 0xff. Header is kept as

short as possible. Never route this message

through Sony cameras.

CAM_PingPong_

Reset

8x ae ff

Reset ping ctr to 0.

CAM_Ping

8x af 0p 0q 0r 0s

[256 bytes data] ff

pqrs = Pingval. Camera will respond with

OK if correct pingval received. Increase ctr

with 1 for next packet. Data section will be

dumped to stdout if it fails.

CAM_Stdin

8x a4 [0-256 bytes

stdin] 00 ff

Send command to the command

interpreter.

CAM_Debug_

Mode

8x 01 39 0q ff

q=0: Debug mode off.
q=1: Debug mode on. Camera will send

stdout as visca messages in the following

format:

CAM_Boot

8x 01 42 ff

Reboot the camera. This will also reset serial

speed to 9600.

CAM_Speed

8x 01 34 0p ff

p=0: Serial speed 9600. p=1: Serial speed

115200. Reply will be sent before the speed

switch takes place. Please wait 20ms after ok

before sending new commands.

The VISCA™/RS–232 control protocol, cont...

Software upload commands

The CRC algorithm used, is the same as in the XModem protocol. CRC for the last data packet is

only calculated for the actual data bytes in the packet. Pad last packet with 0x00 so that the data

section is 256 bytes long. The PacketID counter starts at 0.

Other commands

NOTE:

Some VISCA™ commands do not apply to the PrecisionHD 1080p4x/4xS2 cameras.
