APPENDIX E • SERIAL COMMANDS
122
RETURN VALUES
The command will return the updated condition of the MTRX information in the same format as the command.
If Command Returns
The cross point of Input 9 is selected to be present on Output 4 DEVICE MTRX 9 I 4 O 1
The gated audio of Input 1 is selected to be present on Expansion Bus W DEVICE MTRX 1 I W E G
Matrix Attenuation Adjust
DESCRIPTION:
This command selects/reports the matrix level at the cross point.
** Note: Values indicate entry range only. Actual internal range of the gain stage is from –60 to 0 and absolute values
will be limited to the internal gain range. Absolute levels below –60 will mute the gain stage.
RETURN VALUES:
Unit always returns the last executed MTRXLVL selection in the same form as above.
TEXT FORM DETAILS
COMMAND FORM:
<DEVICE> MTRXLVL < SrcChannel > < SrcGroup > < Dest Channel > <Dest Group> [Value A/R]
Where:
DEVICE: See General Text command form Description
MTRXLVL Text Command
Src Channel See Groups and Channels (Table 1, page 95)
Src Group ‘I’, ‘M’, ‘P’, ‘L’, ‘E’ See Groups and Channels (Table 1, page 95)
Dest Channel See Groups and Channels (Table 1, page 95)
Dest Group ‘O’, ‘P’, ‘E’ See Groups and Channels (Table 1, page 95)
Value Selects the amount of attenuation at cross point in dB. If null command returns current
attenuation
A/R
X=R parameter to indicate relative
X=A parameter to set the gain to an absolute value
X=Null parameter will default to R (relative)
RETURN VALUES
The command will return the updated level of the matrix for the selected source and destination in the same format
as the command was issued. All return gain values are absolute and reflect the actual internal gain in the matrix.
If Command Returns
Input 9 and Output 9 cross point level is desired (level was previously set to –10dB) DEVICE MTRXLVL 9 I 9 O –10
Input 3 and Expansion Bus W cross point level is desired to be –6dB DEVICE MTRXLVL 3 I W E –6
