Digital Sync Validation Processing
List individual sync
frequency X!LS X1%,X1%] Listed as H freq., V freq.
Example: 2LS 031.50,060.00]Input 2 frequency is 31.5
kHz horizontal and 60 Hz
vertical.
N The matrix switcher returns 000.00,000.00 if there is no connection or sync frequencies are not applicable.
View all input connections 0LS X1^1 X1^2 X1^3•...•X1^n]Each X1^ response is the
connection status of an
input, starting from input 1,
n is the maximum number of
inputs for this model.
Video mute commands
RGB mute X#*1B VmtX#*1]Mute output X# RGB
(video off).
RGB unmute X#*0B VmtX#*0]Unmute output X# RGB
(video on).
Read RGB mute X#BX(] 1 = mute on, 0 = mute off.
Global RGB mute 1*B Vmt1]Mute all RGB outputs.
Global RGB unmute 0*B Vmt0]Unmute all RGB outputs.
RGB delay
Set RGB delay EX#*X1#D}OutX#•DlyX1#]
Example: E13*7D}Out13•Dly07]Set the RGB interval for
switches to output 13 to 3.5
seconds (7 x 0.5 seconds).
Read RGB delay EX#D} X1#]
Example: E14D}05]Output 14 interval is 2.5
seconds (5 x 0.5 seconds).
Audio input gain and attenuation
N The set gain (G) and set attenuation (g) commands are case sensitive.
Set input audio gain to +dB
value
X!*X%G InX!•AudX$]
Example: 1*2G In01•Aud+02]Set input 1 audio gain to
+2 dB.
Set input audio attenuation
to -dB value
X!*X%g InX!•AudX$]
Increment gain X!+G InX!•AudX$] Increase gain by 1 dB.
Example: 5+G In05•Aud+03]Increase audio input 5 level
from +2 dB to +3 dB.
Decrement gain X!-G InX!•AudX$] Decrease gain by 1 dB.
Example: 7-G In07•Aud-09]Decrease audio input 7 level
from -8 dB to -9 dB.
Read input gain X!GX$]
Audio output volume
N The table on page 4-10 defines the value of each audio volume step.
Set the audio volume to a
specific value
X#*X&V OutX#•VolX&]
Example: 1*50v Out01•Vol50]Set output 1 volume to 79%.
Increment volume X#+V OutX#•VolX&] Increment volume by 1 step.
Example: 1+V Out01•Vol51]
Decrement volume X#-V OutX#•VolX&] Decrease volume by 1 step.
Read output volume X#VX&]
