Using the Command/Response Table
The command/response table begins on the next page. Except for the gain and
attenuation settings, upper or lower case letters are acceptable in the command
field. Command and response examples are shown throughout the table.
The table below shows the hexadecimal equivalent of each ASCII command.

Symbol definitions
Symbols (
X
values), defined below, are used throughout the command/response
table that begins on page 4-4. The symbols represent variables in the command/
response table fields.
= CR/LF (carriage return/line feed) (hex 0D 0A)
= CR (no line feed)
• = Space
Esc
= Escape key
X
= Input number 1 through 8
X
= Switcher resolution:
01 = 640 x 480 (VGA) 11 = 480p
02 = 800 x 600 (SVGA) 12 = 576p
03 = 1024 x 768 (XGA) 13 = 720p
04 = 1280 x 1024 (SXGA) 14 = 1080i
05 = 1024 x 852 15 = 1080p
06 = 1024 x 1024 16 = 1280 x 768
07 = 1366 x 768 17 = 1440 x 900
08 = 1365 x 1024 18 = 1680 x 1050
09 = 1400 x 1050 19 = 1280 x 800
10 = 1600 x 1200 (UXGA) 20 = 852 x 480
X
= Video refresh rate:
1 = 50 Hz 3 = 75 Hz
2 = 60 Hz
X
= On/off status (0 = off, 1 = on)
X
= Picture adjustment range (000 through 128)
X
= Horizontal shift range (000 through current horizontal
output resolution)
X
= Vertical shift range (000 through current vertical
output resolution)
X
= Sharpness level (00 through 128)
X
= Horizontal start position (000 thru 200)
X10
= Vertical start position (000 thru {variable})
X11
= Pixel phase value (0 to 31)
X12
= Gain value (numeric dB value, 0 to +9)
X13
= Attenuation value (numeric dB value, -1 to -53)
X14
= Gain/attenuation (-53 dB to +9 dB, each step = 1 dB)
X15
= Output volume (0 to 100)
X16
= Detected input signal standard (input 1 through 4 or 5):
0 = none 3 = NTSC 4.43
1 = NTSC 3.58 4 = SECAM
2 = PAL
X17
= Input 5 video type:
0 = Interlaced component 2 = HDTV
1 = Progressive component
X18
= PIP size:
00 = 1/4 (default) 03 = 1/25
01 = 1/9 04 = Side-by-side normal
02 = 1/16 05 = Side-by-side full screen
X19
= Output video type:
0 = Y, B-Y, R-Y 2 = RGBS
1 = RGBHV 3 = RGsB
X20
= Output sync polarity:
0 = H–/V– 2 = H+/V–
1 = H–/V+ 3 = H+/V+
X21
= Aspect ratio (0 = 4:3, 1 = 16:9)
X22
= Menu buttons:
00 = Menu 03 = Left
01 = Up 04 = Right
02 = Down 05 = Enter
X23
= Pixel and line values (The range depends on the input
resolution applied and the output resolution selected.)
X24
= Audio follow:
0 = Follow main window 2 = Toggle audio source
1 = Follow PIP window
X25
= Window size (The range depends on the input
resolution applied and the output resolution selected.)
