Storage
A single character that specifies the storage table to which the 
command is applied.  An exclamation point (!) performs the com-
mand’s operation on the device’s volatile menu configuration table.  
A period (.) performs the command’s operation on the device’s 
non-volatile menu configuration table.  Use the non-volatile table 
only for semi-permanent changes you want saved through a power 
cycle.
Query Commands
Several special characters can be used to query the device about its settings.
^
What is the default value for the setting(s).
?
What is the device’s current value for the setting(s).
*
What is the range of possible values for the setting(s).  (The de-
vice’s response uses a dash (-) to indicate a continuous range of 
values.  A pipe (|) separates items in a list of non-continuous val-
ues.)
Tag Field Usage
When a query is used in place of a Tag field, the query applies to the 
entire set 
of commands available for the particular storage table indicated by the Storage 
field of the command.  In this case, the SubTag and Data fields should not be 
used because they are ignored by the device.  
SubTag Field Usage 
When a query is used in place of a SubTag field, the query applies only to the 
subset of commands available that match the Tag field.  In this case, the Data 
field should not be used because it is ignored by the device.
Data Field Usage
When a query is used in place of the Data field, the query applies only to the 
specific command identified by the Tag and SubTag fields.
Concatenation of Multiple Commands
Multiple commands can be issued within one Prefix/Storage sequence.   Only the 
Tag, SubTag, and Data fields must be repeated for each command in the 
sequence.  If additional commands are to be applied to the same Tag, then the 
new command sequence is separated with a comma (,) and only the SubTag and 
Data fields of the additional command are issued.  If the additional command 
requires a different Tag field, the command is separated from previous 
commands by a semicolon (;).
Responses
The device responds to serial commands with one of three responses:
