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 =

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
