•  Checksum Transmission: This parameter specifies whether the checksum 

character is included in the data being transmitted. 

•  Code Length Qualification: Because of the weak structure of the 2 of 5 

codes, a partial scan has a high probability of decoding as a valid but shorter 
2 of 5 codes (known as short scan). To prevent this kind of undesired 
reading, the Code Length settings can help to insure that the correct code is 
read by qualifying the allowable code length. Code length parameters can be 
configured in two ways: Fixed Code Length or Max / Min code length. If 
the fixed code length is selected, up to 2 fixed lengths can be specified. And 
if max / min code length is selected, the max length and the min length must 
be specified, and the scanner will only accept those codes with lengths fall 
between max / min length specified. 

 

 

•  Start/Stop Transmission: This parameter specifies whether the start/stop 

characters of Codabar are included in the data being transmitted. 

•  Start / Stop Selection: Four different start / stop pairs can be selected as 

start / stop characters as listed below. 

abcd / abcd 
abcd / tn*e 
ABCD / ABCD 
ABCD / TN*E 
 

 

•  System Number Selection: The UPCE comes with 2 formats: System 

Number 0 and System Number 1. These two differ in the method of 
encoding data. The system number 1 is the new UPCE extension to the 
ordinary UPCE (system number 0). Users have the choice of enabling two 
system numbers or just system number 0. 

•  Convert to UPCA: If this parameter is enabled, the UPCE read will be 

expanded into UPCA, and the following processing will follow the 
parameters configured for UPCA.

•  System Number Transmission: If this parameter is enabled, the system 

number will be included in the data being transmitted. 

•  Checksum Transmission: If this parameter is enabled, the checksum 

character will be included in the data being transmitted. 

 

 

•  Convert to EAN13: If this parameter is enabled, the EAN8 read will be 

expanded into EAN13, and the following processing will follow the 
parameters configured for EAN13. 

•  Checksum Transmission: If this parameter is enabled, the checksum 

character will be included in the data being transmitted. 

 

 

•  Convert to EAN13: If this parameter is enabled, the UPCA read will be 

expanded into EAN13, and the following processing will follow the 
parameters configured for EAN13. 

•  System Number Transmission: If this parameter is enabled, the system 

number will be included in the data being transmitted. 

•  Checksum Transmission: If this parameter is enabled, the checksum 

character will be included in the data being transmitted. 

 

 

•  ISBN / ISSN Conversion: If these parameters are enabled, the scanner will 

convert the code read into ISBN or ISSN code if the formats are correct 
(EAN13 codes start with 978 or 979 for ISBN, and 977 for ISSN). 

•  Checksum Transmission: If this parameter is enabled, the checksum 

character will be included in the data being transmitted.
