The symbology identifiers use groups of numbers to identify each

symbology

. The range of possible values could potentially span 100 for each

symbology category. The Symbology Identifier Table lists each identifier group
with the corresponding symbology.

A no read condition is indicated by all four bytes yy, M and N set to 0 in a

transmission. All other data is therefore not valid.

See the ~OS# command (

page 6-18

) for other transmission data formats.

Symbology Identifier Table

Three digit number shows total scans-on-

000-999; Good Quiet Zones (scans)

Two digit number shows Lead QZ. Units:
.1X (00-9A)

Two digit number shows Trail QZ. Units:
.1X (00-9A)

One digit number: ‘0’ (off), ‘1’ (on). Sync
