How can I read the serial number of a DS-457 via SSI?

Hi,

 

we use the DS-457 scanner in our electronic safety lockers. For our half-automated inspection process, it would be great if we could read the serial number of the scanner via SSI.

 

The docs (DS457 FIXED MOUNT IMAGER INTEGRATION GUIDE, 72E-144361-04 Revision A March 2015, https://www.zebra.com/content/dam/zebra_new_ia/en-us/manuals/barcode-scanners/ds457-integration-guide-en-us.pdf )

say on page 140:

 

     REQUEST_ID, Opcode 0xA3: Request the imager's serial number

 

but in the next line, the same Opcode 0xA3 is described as:

 

     REQUEST_REVISION, Opcode 0xA3: Request the imager's configuration.

 

If Opcode 0xA3 is requested via SSI (04 A3 04 00 FF 55), the device returns the imager's configuration, but I need the serial number.

Seems to be an error in the docs here, so how can I get the serial number of a DS-457?

 

Greetings
