12 - 46 DS8178 Digital Scanner Product Reference Guide
Convert I 2 of 5 to EAN-13
Parameter # 82 (SSI # 52h)
Enable this parameter to convert 14-character I 2 of 5 codes to EAN-13, and transmit to the host as EAN-13. To
accomplish this, the I 2 of 5 code must be enabled, and the code must have a leading zero and a valid EAN-13
check digit.
I 2 of 5 Security Level
Parameter # 1121 (SSI # F8h 04h 61h)
Interleaved 2 of 5 bar codes are vulnerable to misdecodes, particularly when I 2 of 5 Lengths is set to Any Length.
The digital scanner offers four levels of decode security for Interleaved 2 of 5 bar codes. There is an inverse
relationship between security and digital scanner aggressiveness. Increasing the level of security can reduce
scanning aggressiveness, so select only the level of security necessary.
•
I 2 of 5 Security Level 0: This setting allows the digital scanner to operate in its most aggressive state, while
providing sufficient security in decoding most in-spec bar codes.
•
I 2 of 5 Security Level 1: A bar code must be successfully read twice, and satisfy certain safety
requirements before being decoded. This default setting eliminates most misdecodes.
•
I 2 of 5 Security Level 2: Select this option with greater bar code security requirements if Security Level 1
fails to eliminate misdecodes.
•
I 2 of 5 Security Level 3: If you selected Security Level 2, and misdecodes still occur, select this security
level. The highest safety requirements are applied. A bar code must be successfully read three times before
being decoded.

NOTE Selecting this option is an extreme measure against mis-decoding severely out-of-spec bar codes.
Selecting this level of security significantly impairs the decoding ability of the digital scanner. If this
level of security is required, try to improve the quality of the bar codes.
