Appendix C Enabling or Disabling Symbologies The SD Scan Card 3E is pre-set to automatically detect
and decode (auto-discriminate) the most common bar
code symbologies. To enable or disable symbologies,
simply use SocketScan’s Symbology Selector.
Notes:
• The supported length of some symbologies will change
after Symbology Selector is used. See Table 1.
• With more symbologies enabled, the scanner must
work harder to search through all the possible
combinations. This may make the decoding process slightly longer.
