22 | APPENDIX D: ENABLING/DISABLING SYMBOLOGIES
Appendix D Enabling or Disabling
Symbologies
The Cordless Hand Scanner 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 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.
• The advanced symbology parameters listed in Table 2 can only be modified
by using the SocketScan SDK. Check Socket’s website for updates.
