Command/Response Tables for Audio SIS Commands

DSP control commands are an extension to SIS commands. They differ only in their data string and the requirement to send each command with an “Au” suffix.

Symbol definitions

]

=

CR/LF (carriage return/line feed) (hex 0D 0A)

}

=

Carriage return (no line feed, hex 0D)

 

 

(use the pipe character, , for Web browser commands))

•= Space character

=

Pipe (vertical bar) character

E= Escape key (hex 1B) (use W instead of Esc for Web browsers)

NOTE: The dB values of the level settings are in 0.1 dB increments using negative numbers but not decimal

places. Multiply the desired level setting by ten for the SIS command value.

Example: To set an input level to 45.2 dB, use 452. To set an input level to -12.5 dB, use -125.

X6)

=

Gain and trim control or mix-point select

X6!

=

Level value in dB;

X6@ = Input Polarity

See “Table 1. Level Control and Mix-point Selection Tables.”

dB value, in 0.1 dB increments using negative numbers but not decimal

places. The valid range depends on the type of gain block specified in the X6) command: The valid range depends on the control or mix-point.

A = –180 to 240 (–18 to +24 dB)

B = –1000 to 60 (–100 to +6.0 dB)

C = –240 to 120 (–24 to +12 dB)

D = –120 to 60 (–12 to +6.0 dB)

E = –1000 to 0 (–100 to 0.0 dB)

0 = Standard

1 = Inverted

X6$

=

Mute status

0 = unmute

 

 

 

 

1 = mute

 

X6%

=

Group master group number

01 – 16

 

X6^

=

Group fader setting

dB value, in 0.1 dB increments using negative numbers but not decimal places.

 

 

 

The valid range depends on the type of gain block that is assigned to the group

 

 

 

number (X6%) specified in the command:

 

 

 

A = -180 to 800

(-18.0 dB to +80.0 dB)

 

 

 

B = -1000 to 120

(-100.0 dB to +12.0 dB)

 

 

 

C = -350 to 250

(-35.0 dB to + 25.0 dB)

 

 

 

D = -120 to 120

(-12.0 dB to +12.0 dB)

 

 

 

E = -1000 to 000

(-100.0 dB to +0.0 dB)

X6&

=

Group fader increment

X6*

=

Group fader soft limit

X6(

=

Group type

X7)

=

Personal Identification Number (PIN)

NOTE:

Leading zeros are ignored.

dB value, in 0.1 dB increments, to raise or lower a group fader

dB value, in 0.1 dB increments. The valid range X6^ must be within the range for the gain block grouped in X6%.

6 = gain

12 = mute

Four numeric digits, default = 0000
