0 = off (default), 1 = on

Example: enable auto switch mode.

Example:

(default) (RGB & sync output)

0 = off

and additional descriptions

0 = off,

1 = on,

Example: enable enhanced mode.

0 = RGB

1 = YUV

2 = RGsB (sync on green, SOG) Example: RGB sync output

0 = H-/V- (default)

1 = H-/V+

2 = H+/V-

3 = H+/V+

Example: H-/V+ sync polarity

The syntax for setting a special function is X? * X! # where X? is the function number and X! is the value. To view a function’s setting, use X? # where X? is the function number. In the following table the values of the X? variable are different for each command/function. These values are given in the rightmost column.

RGB delay 3 * X!

Example:3*7#

#	RGB	X!	0	= 0.0 seconds (default),
			1	= 0.5 seconds, 2 = 1.0
			seconds, ... in ½ second steps
			up to 10 = 5.0 seconds
	RGB07		Example: 3.5 second RGB delay
