128 HF680 Series User Guide
SubTag A 3 character case-insensitive field that identifies the desired menu
command within the tag group. For example, the SubTag for the
RS232 baud rate is BAD.
Data The new value for a menu setting, identified by the Tag and SubTag.
Storage A single character that specifies the storage table to which the com-
mand is applied. An exclamation point (!) performs the command’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 device’s
response uses a dash (-) to indicate a continuous range of values. A
pipe (|) separates items in a list of non-continuous values.)
:Name: Field Usage (Optional)
This command returns the query information from the scanner.
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.
