Command/response table for special function SIS commands

The syntax for setting a special function is __ * X? #, where __ is the function number and X? is the value. To view a function’s setting, use __#, where __ 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 right column.

Delay times

 

 

 

 

 

 

 

 

 

 

Set the RGB delay (Triple-Action Switching). 3 * X? #

RGBDly*X? ]

0

= 0.0 seconds (default), 1 = 0.5

 

 

 

 

seconds, 2 = 1.0 seconds,

 

 

 

 

... in ½ second steps up to

 

 

 

 

10 = 5.0 seconds

 

Example:

3*7#

RGBDly*07]

Example: 3.5 second RGB delay.

 

Audio settings

 

 

 

 

 

Set the preamp output mode.

18 * X? #

PreAmpMod* X? ]

Set the line level audio

 

 

 

 

(Lineout’s and Preamp’s)

 

 

 

 

outputs to be either mono or

 

 

 

 

stereo signals.

 

 

 

 

1

= mono

PRELIMINARY

 

 

 

2

= stereo (default)

 

 

 

 

N If mono is selected, the audio signal is the same on both the left and right channels.

 

 

If stereo is selected, the switcher sends out different (stereo) signals on the left and right channels.

 

Set the loudness control.

29 * X? #

Loudness*X? ]

When output volume is low,

 

 

 

 

provide a +6 dB boost at 100Hz

 

 

 

 

and at 10 kHz. When output

 

 

 

 

volume is high, decrease the

 

 

 

 

boost at those frequencies.

 

 

 

 

This improves sound richness

 

 

 

 

by restoring the high and low

 

 

 

 

frequencies to which the ear is

 

 

 

 

insensitive to at low volume

 

 

 

 

levels. The effect diminishes as

 

 

 

 

volume is increased.

 

 

 

 

0

= off (default for firmware ver.

 

 

 

 

2.1 and higher) (remove boost)

 

 

 

 

1

= on (default for firmware ver.

 

 

 

 

2.0 and lower) (turn boost on)

 

Set line level audio outputs’ levels

40 * X? #

LineLevel*X? ]

1

= -10 dBV (-8 dBu, 0.32 Vrms),

 

 

 

 

unbalanced output (default)

 

 

 

 

2

= +4 dBu (+6 dBV, 1.23 Vrms),

 

 

 

 

balanced output

 

N If the connector is wired for balanced output, the level is +6 dB higher than if it is wired for unbalanced output.

 

 

 

 

 

 

 

Mode selection

 

 

 

 

 

Select the Monitor Out output mode 28 * X? #

MonitorOutOpt*X? ]

See pages 3-7 and 3-8 for an

 

 

 

 

explanation of these modes.

 

 

 

 

1

= mode 1 (RGB follow mode)

 

 

 

 

2

= mode 2 (DA mode)

 

 

 

 

3

= mode 3 (standard mode)
