Software Configurations
Transmit Start/Stop Character
A “yes” allows the start and stop characters to be transmitted to the host device. With a “no” response, the start and stop characters are not
transmitted.
Full ASCII
A “yes” selects Full ASCII, which directs the decoder to evaluate the existing code as an extended Code 39. With a “no” response, the existing
code is evaluated and output as a standard Code 39.
Output Hex ASCII
A “yes” directs the decoder to output the code content in hex ASCII format. With a “no” response, ASCII output format is used.
INTERLEAVED 2/5 (Interleaved 2 of 5)
A numerical code with the following character set: 10 digits (0 to 9); one start character; one stop character.

Code Length (free/interval/fixed)
The scanner can be programmed to read bar codes of any length or only those of a particular length (entered by the user):
“free”
- Bar codes of any length between 1 and 49 characters will be read.
“interval” - User may enter a range of lengths within which the scanner will read the codes. Valid value 1 to 49.
“fixed”
- User may program up to five different fixed lengths to be read by the scanner. Valid value 1 to 49.
Code length for Interleaved 2/5 includes the number of useful characters plus the check digit and is determined from the total number of wide
elements (bars or gaps) as follows:
(wide elements – 1)
Code Length = ––––––––––––––––––––

Multiple Reads (1-99)
Enter the number of identical reads the scanner must decode (in one reading gate) before transmitting the result to the host device. This process
increases output reliability. The selected scanning frequency and the speed at which the bar code is moving past the CLV should be considered
when making this selection. If the number of multiple reads specified by the user is not fulfilled, the CLV will send the bar code string or error
string (software selectable) to the host, along with the error status ST=5 if the ST value has been placed in the separator.
