Please refer to section 7.1 for more information

regarding synchronising the uCAM-II.

5.3. Auto-Baud Detect

The module can auto-detect the baud rate of the

incoming command. The host should make

connection with one of the following baud rates:

•

9600 bps

•

14400 bps

•

56000 bps

•

57600 bps

•

115200 bps

•

921600 bps

The module will keep using the last baud rate either

autobauded or manually set until the next power

cycle, or “full reset”.

Note: The baud rate can be set higher than the

baud rated determined by the Auto-Baud detect

function. Refer to Section 5.4

5.4. Setting the Baud Rates

You can set Baud rates using the Set Baud

command, refer to the table in section 6.5

Note: Baud rate changes holds until “full reset”

command is sent or Power cycle occurs. So, you can

synchronise at any of the Auto-detect Baud rate.

5.5. Sleep mode

After the camera has been idle for 15 seconds it

enters sleep (low power) mode. To wake up the

camera in this state it is necessary to send the ‘Sync’

command. If the camera is required to stay awake,

it is recommended to periodically end a ‘Sync’

command, such as every 10 seconds, to prevent the

camera going to sleep if no other commands are

being sent. If communications are occurring

between the Host and the camera, the camera will

not go to sleep until it has been idle for 15 seconds.
