Code 39
Max Number of Auto Retry
The value assigned for this parameter governs the number of times the imager will attempt
to capture a bar code if the first attempt fails to a maximum of 99 times.
Decoder Timeout
This parameter determines the maximum time that the decoder will spend searching for
barcode on captured image. The value assigned here is dependent on the type of bar code
and quality of the image being capture. For example, the value may need to be increased to
compensate for larger bar codes with more data encoded or for poor quality images. On the
other hand, the value can be decreased for smaller, good quality images. The allowable
value ranges from 200 to 500 msec.
Single Target Mode Enabled
When this parameter is enabled, the decoder assumes that a single bar code exists in the

code identifier. When this parameter is enabled, the AIM ID is inserted at the beginning of
the decoded bar code.

When Start/Stop Strip is enabled, start/stop characters are not output.
Check Char
When this parameter is enabled, before data is output, the "Code 39" symbol integrity is ver-
ified based on a parity character that must be present in the code. If the parity character is not
