Latest switching test with the script was ok. The only change is the position of the boards on the table.--Oleg 10:01, 22 September 2008 (CDT)

Sequence(no need in sensros_init):

1) camera_demo.php
2) (telnet) switch on test pattern
3) "get frame" 
4) "switch to channel 2"
5) (telnet) switch on test pattern
5) adjust phase
5) "get frame"
6) "switch to channel 1"
7) "switch to channel 2"
...

Current "camera_demo" script:

Are the frames become broken after:

1) camera_demo.php
2) sensors_init.php
3) "get frame" 
4) "switch to channel 2"
5) "get frame"
6) "switch to channel 1"

If yes, does turning off the compressor help? I mean:

change channel -> compressor start -> get frame -> compressor stop -> change channel

If you don't use sensors_init.php after camera_demo.php you can try to move function dcm_reset() from sensors_init.php to camera_demo.php before getting a frame.
