3-3DVS 406 • Serial Communication
X12
= Detected input signal standard (0 through 4)
0 = none
1 = NTSC 3.58
2 = PAL
3 = NTSC 4.43
4 = SECAM
– = not applicable (occurs when the input is
set for RGB, YUV, or progressive YUV)
X13
= Detail level (0 through 63)
X16
= Executive mode status (0 through 2)
0 = disabled (executive mode off, normal mode
on)
1 = enabled, image adjustments are locked
X17
= Blanking adjustment range (0 through 127 lines)
X18
= Sharpness level (0 through 63)
X19
= Input configuration preset (1 through 3)
X20
= Scaler refresh rate
1 = 50 Hz
2 = 56 Hz (1280x768 only)
3 = 60 Hz
4 = 75 Hz
5 = AFL* (50 Hz for PAL or 59.94 Hz for
NTSC)
6 = True rate (72 Hz for NTSC or 100 Hz for
PAL)
7 = not applicable
Using the command/response tables
The command/response tables on the next page list valid command ASCII codes,
the scaler’s responses to the host, and a description of the command’s function
or the results of executing the command. Except when setting audio gain/
attenuation, detail, and sharpness, upper and lower case characters may be used
interchangeably in the command field.
The ASCII to HEX conversion table at left is for use with the
command/response tables.

ASCII to HEX Conversion Table
•
The command/response tables use symbols (defined below) to represent variables.
Symbol definitions
= CR/LF (carriage return/line feed) (hex 0D 0A)
• = Space
Esc
= Escape key
X1
= Specific input number (1 through 6)
1 = input 1, 2 = input 2, and so forth
X2
= 0 = off, 1 = on
X4
= Video signal type (1 through 8)
1 = RGB pass-through
2 = YUV pass-through
3 = RGBcS
4 = YUVi, interlaced
5 = YUVp, progressive
6 = composite video
7 = S-video
8 = SDI (serial digital interface)
X6
= Audio gain (0 through 9) in 1 dB steps
X7
= Audio attenuation (1 through 15) in 1 dB steps
X8
= Controller firmware version (listed to
two decimal places e.g.: x.xx)
X9
= Numeric value (-15 through +9) in dB
X10
= Picture adjustment range (0 through 255)
X11
= Scaler resolution
1 = 640x480 9 = 1365x1024
2 = 800x600 10 = 1400x1050
3 = 848x480 11 = 480p
4 = 852x480 12 = 576p
5 = 1024x768 13 = 720p
6 = 1280x768 14 = 1080p
7 = 1280x1024 15 = 1080i
8 = 1360x765 16 = Lock to input 1*
* Lock or AFL is Accu-RATE Frame Lock
