Command/response table for special function SIS commands
The syntax for setting a special function is
X?
*
X n
# where
X?
is the function number
(such as 3 for the “set RGB delay” command in the first example below),
X n
is the
value or variable (such as 35 in the first example below), and # is the execute
command. 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.

Delay times
RGB delay (Triple-Action Switching) 3* X13 # Dly X13 Adjustable in 0.01 second steps
up to 50 = 5.0 seconds. 0 = 0.0
seconds (default), 1 = 0.1
seconds, 2 = 0.2 seconds, and so
on.
Example: 3*35# Dly35 RGB delay set to 3.5 seconds.
Scaler settings
Output signal 6* X5 # Tpo X5 0 = RGB (default).
1 = Component (Y, R-y, B-y).
Example: 6*1# Tpo01 RGB output signal.
Output polarity 7* X6 # Pol X6 0 = H-/V- (default).
1 = H-/V+.
2 = H+/V-.
3 = H+/V+.
Example: 7*1# Pol01 Example: H-/V+ output
polarity.
Blue screen
Blue screen 8* X7 # Blu X7 0 = off (normal output).
(output blue and sync only) 1 = on (blue video & sync output).
Example: 8*1# Blu1 Blue & sync output as a tool for
system setup.
Edge smoothing
Edge enhancement 16* X7 # Fil X7 0 = off
1 = on (default)
Example: 16*1# Fil1 Enable edge smoothing.
