Concatenation Of Multiple Commands; Responses; Examples Of Query Commands - Honeywell 4800dr - Document Camera Imaging Manual

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 avail-
able 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 dif-
ferent 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 #1:What is the range of possible values for Imaging Style?
Enter: snpsty*.
Response: SNPSTY0-2[ACK]
This response indicates that Imaging Style (SNPSTY) has a range of values from 0 to 2.
Example #2: What is the default value for Imaging Style?
Enter: snpsty^.
Response: SNPSTY1[ACK]
This response indicates that the default setting for Imaging Style (SNPSTY) is 1, or Photo.
2 - 2
