FAQ of Barcode Scanner Module

Problem: Barcodes cannot be read.

Solution:

1. Find out the barcode type and verify that the barcode type is enabled. If the barcode parameters include check digit verification, select the Disable option.

2. If you do not know the barcode type, enable all symbologies.

3. If they are inverse barcodes (bright images on a dark background), enable the Video Reverse feature.

?

Problem: Incorrect output.

Solution:

1. If this problem happens to all barcodes and additional characters appear before/after barcode data, disable all prefix/suffix.

2. If this problem only happens to some barcodes and matches one of the following situations:

a) incomplete barcode data: Enable the check digit verification.

b) both the first and last characters are asterisks (*): Disable the transmission of start/stop characters of Code 39.

c) “a” transmitted as “+A”: Enable Code 39 Full ASCII.

?

Problem: Barcodes can be read, but cannot be displayed.

Solution: Verify that the serial port parameter (such as baud rate, data bit and stop bit) settings match the host

Requirements.

?

Problem: Illumination and aiming beams are OFF.

Solution:

1. Verify that the engine is properly powered up.

2. Send “?” to the engine. If the engine returns a reply of “!”, then send programming commands to turn on

illumination and aimer.
