Dsp Power 80h = Display device power is Off
81h = Display device power is On
Dsp Mute
80h = Mute Off (picture on)
81h = Mute On (picture off)
Sys Pwr
80h = System 4
xi
power is Off
81h = System 4
xi
power is On
Max Chnl
80h - 96h (maximum number of inputs on system)
Dly Time
80h - 8Ah (RGB time delay in half seconds)
EOT
04h = End of transmission
Response example:
1Bh, 35h, 80h, 82h, 81h, 83h, 85h, 81h, 80h, 81h, 84h, 85h, 04h
Translates to:
ESC, CMD5, ERC, Video Channel #2, Audio Channel #1, S-Video mode,
Hughes projector, Dsp Power is On, Dsp Mute is Off, System Power is On, Max
channel # is 4, and the RGB time delay is 2.5 seconds.
Change System Settings - CMD6 (36h)
Change settings, and/or make adjustments to the system. This command allows
incremental adjustments to be made to System 4
xi
settings, for the currently-
selected input channel.
Format: ESC, CMD6, Subcom6.1, Subcom6.2, EOT
Where: ESC, CMD6 =
1Bh, 36h
Subcom6.1 =
Function to adjust
80h = Horizontal Shift
81h = Contrast
82h = Color
83h = Tint (Hue)
84h = Audio level
85h = RGB time delay (0.5 second steps)
Subcom6.2 =
How much to adjust
80h = Adjust up 1 step
81h = Adjust down 1 step
Example: Adjust Audio level down = 1Bh, 36h, 84h, 81h, 04h
Response: ESC, CMD6, ERC, EOT
_______ This command is optimized to be used as an audio fader control for systems
which require this feature.
Set Slave Configuration - CMD8 (38h)
Set up the System 4
xi
for slave configuration. The System 4
xi
can have another
type of switcher connected to input channel 4 as a slave. In order to
communicate with the slave, the System 4
xi
must know what type of switcher is
being used.
Format: ESC, CMD8, Slave, EOT
Where: ESC, CMD8 =
1Bh, 38h
Slave
80h = No slave connected
84h = SW4MX switcher connected
86h = SW6MX switcher connected
88h = System 8 Plus switcher connected
8Ah = System 10 Plus switcher connected
8Fh = Multiple System 8/10 Plus switchers
Response: ESC, CMD8, ERC, EOT
