Rev. C
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:
ACK Indicates a good command which has been processed.
ENQ Indicates an invalid Tag or SubTag command.
NAK Indicates the command was good, but the Data field entry was out of the
allowable range for this Tag and SubTag combination, e.g., an entry for a
minimum message length of 100 when the field will only accept 2 characters.
When responding, the device echoes back the command sequence with the
status character inserted directly before each of the punctuation marks (the
period, exclamation point, comma, or semicolon) in the command.
Examples of Query Commands
In the following examples, a bracketed notation [ ] depicts a non-displayable response.
Example: Example #1:What is the range of possible values for Codabar Coding
Enable?

Enter : cbrena*.

Response : CBRENA0-1[ACK]
This response indicates that Codabar Coding Enable (CBRENA) has a range of values from 0 to 1
(off and on).
Example: Example #2: What is the default value for Codabar Coding Enable?

Enter : cbrena^.

Response : CBRENA1[ACK]
This response indicates that the default setting for Codabar Coding Enable (CBRENA) is 1, or on.
