Many consumers will have a test after the bar code scanning gun, but for those consumers who are not familiar with the bar code scanning gun, the test may be ignored, or the random test may cause some other situations. Here is how to test the bar code scanning gun for you
1. Pull back the data cable of the scanning gun, and if the cable does not slide out, it means that the connection is good. When the other end is plugged into the corresponding port on the computer, the lower right corner of the computer will prompt to install a hardware driver automatically, and wait for it to finish automatically.
2. After the installation, we open a notepad, TXT document, word document or excel form and other software that can be input (as long as the cursor flashes), and close the input method (be sure to close the input method or switch to the English state). Press the button, the bar code scanning gun will send out a light, the light is aimed at the bar code scanning, then the scanning gun will send out a "drop" sound, the bar code data will be transmitted to the computer text. Here we need to pay attention to avoid scanning the bar code in the manual, because it will make the bar code scanning gun enter the setting state, cannot be used normally, or enter the incorrect configuration. If the setup card is not scanned correctly due to carelessness, the factory settings can only be restored.
3. When scanning, please note that the bar code scanning gun should have a certain distance from the scanned object, so as to scan correctly. Light also needs to be parallel to the bar code, too much left and right direction of the cross is unable to scan the bar code correctly.
4. The above is the test process of the bar code scanning gun with USB interface. If you use the data cable of the serial port, please connect the serial port cable to the serial port of the computer, open a serial port assistant and other software on the computer, select the corresponding baud rate (the common baud rate is 9600 and 115200, and the default speed of the scanning gun is 9600), and then use the bar code scanning gun to scan the bar code, Bar code data will be transmitted to the serial software.
