This section describes user configurable parameters that are pertaining to barcode 
symbologies. 

 

• Standard / Full ASCII Code 39: User can choose to read either Standard 

Code 39 or Full ASCII Code 39 by configuring this parameter. 

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

characters of Code 39 are included in the data being transmitted. 

• Checksum Verification: This parameter specifies whether the scanner will 

perform checksum verification when decoding barcodes. If the checksum is 
incorrect, the barcode will not be read. 

• Checksum Transmission: This parameter specifies whether the checksum 

character are included in the data being transmitted. 

 

 

For Italy /French Pharmacode, there is always a checksum character included in the 
barcode. So the checksum verification is always performed when decoding these 
symbologies. User though can choose whether the checksum character is to be 
transmitted or not. The start / stop transmission of this code shares the same setting 
of Code 39. 

• Checksum Transmission: This parameter specifies whether the checksum 

character is included in the data being transmitted. 

 

 

• Start / Stop Selection: This parameter provides the readability of all 2 of 5 

symbology variants. For example, flight tickets actually use an Industrial 25 
barcode but with Interleave 25 start / stop. In order to read this barcode, the 
start / stop selection parameter of Industrial 25 should set to ‘Interleave 
25.

• Checksum Verification: This parameter specifies whether the scanner will 

perform checksum verification when decoding barcodes. If the checksum is 
incorrect, the barcode will not be read. 

• 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.
