YMBOLOGIES

The CHS is pre-set to automatically detect and decode (auto-
discriminate) the most common bar code symbologies. To enable
or disable symbologies, use the SocketScan Symbology Selector.

Notes:
• The length of some symbologies will change after Symbology

Selector is used. See Table 1.

• Enabling more symbologies will make the scanner work harder

to search through more possible combinations, making the
decoding process slightly longer.

• The advanced symbology parameters listed in Table 2 can only be

modified with the SocketScan Advanced Programming Guide or
SocketScan SDK. Check the Socket website for updates.
