You can find the manual here http://sandevices.com/documents/E682_Operating_Manual.pdf
You may have to change your wiring positions. Here's a snippet from the manual.
"You MUST know the correct color-code used by your pixel strings. This can and will vary
from manufacturer to manufacturer. Wire color is NOT a reliable indication of function.
If in doubt please contact the pixel vendor for clarification. Incorrectly wiring pixel
strings can and will destroy them. Not only must you identify the function of each wire,
but you must properly identify the START end of the pixel string.
If you are using the black 4-wire waterproof cable assemblies from SanDevices or from Ray
Wu, or pixel strings that have those cables pre-attached, the color code for those cables
is as follows:
RED +V pixel power
GREEN Data
BLUE Clock (not used on 3-wire pixels)
BLACK Ground "
