•        Query Commands
For query commands, the entry in the Data field in the syntax above is one of the following characters means:

Item

content

* (HEX: 2A)

What is the scanner’s current value for the setting(s).

& (HEX: 26)

What is the factory default value for the setting(s).

^ (HEX: 5E)

What is the range of possible values for the setting(s).

If {subtag} omitted, means enquiry of all configuration value under the {Tag}. For example, to query all the current settings about Code 11, you should enter 7E 01 30 30 30 30 40 43 31 31 2A 3B 03 (i.e. ~<SOH>0000@C11*;<ETX>).
If {Tag subtag} omitted, means enquiry of all configuration value of the device
Within “available value range”, “-“ means continuous range, “|” means separated value.

 

For example:1|3-5|7|9-20 means all those 17 digits from 1 to 20 except for 2, 6, 8.
For those configuration items having both setup value range and preset value, we use “_” to separate setup value range and preset value, “|” to separate each preset value, and “:” to separate presetting name and preset value.

 

For example: Good read beep frequency range:
GRBFRQ20-20000_Lowest:800|Low:1600|Medium:2730|High:4200;
