i have problem with when i goint to scan after 5 or 10 minutes after it disable, and then we go to connect and disconnect to work

There is no such bar code. barcode scanner scans any barcode and give the result.
scanner can scan in any software. eg. excel,word. dos etc.

Disconnect the scanner from the mouse port or disconnect the mouse from the scanner. The scanner must be connected to the keyboard port and have a keyboard attached to the scanner.

you need to download the pdf manual for this reader whichh you can find in the support page of www.symbol.com.
search within the manual a barcode called set all defaults. this will remove the carriage return after scan.

The first beep is a Good decode beep, the four beeps later are telling that the connection to your PC is not working properly.

Hello, it looks like the scanner lost the settings. As power is there, so connection is ok. The several (four) beeps after reading the barcode means communication error.
Please try to find the original sheet with configuration barcodes or download it from support.symbol.com website, you would need to scan the barcode for IBM PC/AT & IBM Compatibles from Keyboard Wedge Chapter.

There is more than one way for that imager to send data to the computer. Are you using USB, serial, or is there a little box that goes between your existing keyboard and the PC that accepts the scanner connector?
