See the description of the MACROA command for detailed information on creating macros. 
This command is saved to global non-volatile memory and is not part of a preset. Its value is saved each 
time it is changed. It will retain its value after power-down. Since this command writes to non-volatile 
memory, there will be a delay before an acknowledgment is returned. 
8.101. MACROX -- Execute Macro
This command executes the macro corresponding to the specified number. The macro must have been 
previously defined and stored in non-volatile memory via the MACROS, MACROA, and MACROW commands. If 
the specified macro is empty, then an error condition of ERROR#070 will be generated. 
When the MACROX executes, status messages for all of the commands in the macro will be generated (unless 
acknowledgement mode is turned off). The status messages can be suppressed by using the MACROQ 
command, which is exactly the same as MACROX except that status messages are suppressed. 
Example Description Status Message
B01MACROX125
Execute macro number 125.
Status messages for all the commands in the macro will be 
generated first, followed by the message: B01MACROX125
8.102. METER -- Select which Signal is Displayed on the Front 
Panel LED Meter
This command selects which signal is displayed on the front panel LED meter. The options correspond to any 
of the 8 inputs, the telephone input, 8 outputs, the telephone output, the power amplifier output, or the two 
AEC references. The inputs are specified by the labels I1 - I4, IA - ID, and IT (for the telephone input). 
The outputs are specified by the labels O1 - O4, OA - OD, OT (telephone), and OL (power amplifier). The AEC 
references are specified by the labels R1 and R2. 
This command is saved to non-volatile memory only as part of a preset. The state of this command will be 
restored after power-up only if a preset is saved and that preset is set to be the power-on preset. 
Example Description Status Message
B01METERI1
Set front panel LED meter to display the 
signal on input 1 . 
B01METERI1
B01METER?
Query which signal the front panel LED 
meter is currently set to monitor. 
B01METERx , where x is the label 
corresponding to the signal currently being 
monitored. If this command was sent after the 
first example given above, the response would 
be B01METERI1 . 
8.103. MGAIN -- Set Crosspoint Gains in Main Matrix or 
Submatrix
This command sets or queries one or more crosspoint gains in either the main matrix or one of the EF Bus 
submatrices.
