Debug commands for Cisco cameras
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 
pqrstuvw = size, pq=LSB Returns y050 if
ok.
Fatal errors: Returns y06006 if upload
already in progress. Returns y06007 if
unable to access the ash.
SW end 8x 01 50 a1  Sent after last SW packet, instructs camera
to verify new application. Command may take
up to 30 seconds to complete.
Returns y050 if ok. Issue a camera reboot
to activate new software.
Returns y06008 if verication of sw failed.
SW abort 8x 01 50 a3  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  if packet ok.
-> send next one.
Returns y0 60 09  if crc error -> retransmit
packet.
Returns y0 60 0a  if id error
-> retransmit packet
Fatal errors:
y0 60 0b  not in upload mode
y0 60 0c  error writing data to ash
NOTE: Entire message after 8x a0... is raw
data, so it may contain 0x. Header is kept as
short as possible. Never route this message
through Sony cameras.

CAM_Ping * 8x af 0p 0q 0r 0s

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

Send command to the command
interpreter.

8x 01 39 0q  q=0: Debug mode o.
q=1: Debug mode on. Camera will send
stdout as visca messages in the following

CAM_Boot 8x 01 42  Reboot the camera. This will also reset serial
speed to 9600.
CAM_Speed 8x 01 34 0p  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.

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.
* Do not apply to PrecisionHD 4x/4xS2 cameras
