8.66. 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
Q01MACROX125
Execute macro number 125.
Status messages for all the commands in the macro 
will be generated first, followed by the message: 
Q01MACROX125
8.67. 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 3 inputs, 3 outputs, or the AEC reference. The inputs are specified by the labels I1, IA, 
and IB. The outputs are specified by the labels O1, OA, and OB. The AEC reference is specified by the 
label R1. 
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
Q01METERI1
Set front panel LED meter to display the 
signal on input 1 . 
Q01METERI1
Q01METER?
Query which signal the front panel LED 
meter is currently set to monitor. 
Q01METERx , 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 Q01METERI1 . 
8.68. 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
