How to connect barcode scanner to your pc


In order for them to be useful, barcode scanners often have to be connected to computers. We will recall that in virtually all cases, the data which gives meaning to the barcodes they read is stored in databases, which are in turn hosted on computers. What the barcode scanners are meant to do, then, is to transmit the data they scan to the computer, with the computer checking that data against the database in order to assign meaning to it. In most cases, then, scanners without computers will tend to be quite useless. For a scanner to be useful, it has to be connected to the computer. And what we are interested in, for this discussion, is gaining an understanding of the ways through which barcode scanners connect to computers (at the simple, physical, external level).
As it turns out, there are four main ways through which barcode scanners connect to the computers which host the databases upon which they depend:

1. Serial port connection: this is where the scanner comes with a pin which you simply hook onto the serial port of your computer (like where you would hook an extra mouse), and thence connect the barcode scanner to computer. It was, arguably, the first method for connecting barcode scanners to computers to be developed. Its disadvantage is that it is not a plug and play approach. You have to go through quite a lengthy installation process for the barcode scanner, when you go this way. Furthermore, should the scanner 'hang' somewhere in the middle of a computing session, you don't have the option of just unplugging it and then plugging it in again to see whether it will work. Instead, you have to restart the whole machine again, and this can be very disruptive, for instance in the midst of a shopping checkout for a hurried customer. In this system, a scanner would also need specialized software to connect to various computers, meaning that there was no universality in scanner usage.

2. Keyboard wedge connection: this is a connection method where the barcode scanners are put in somewhere between the keyboard and the computer as a 'wedge.' It is something of an improvement on the serial port connection.

3. USB connection: this is what is to be found on most scanners, today. It is where you connect the scanner to the computer using any USB port. A scanner made in this way can, therefore, be used with pretty much any computer. Should it stall midcourse, you have the opportunity to just unplug it, and plug it again, to see if that solves the problem (which it often does). It is also convenient, because in this approach, connecting the scanner to the computer becomes as easy as connecting a USB flash disk to the machine.

4. Wireless connection: this is the emerging technology in ultra-modern scanners, where using systems such as Bluetooth, they are able to connect to the associated databases wirelessly.

Could not active it the scanner on the MC9090


The link works for me DataWedge provides a convenient mechanism for non-scanning aware applications to receive data from embedded or connected data capture devices. It allows the user to capture data into any application that accepts keyboard input. It supports four types of Data Feeds: Barcode Scanners, RFID Tag Readers, MSR Readers and Serial Data Input. It provides user with text/hex data formatting and prefix/suffix facilities. Description
  1. New Test and Log Display.
  2. Improved DataWedge Startup Time for MSR and RFID
  3. Gen2 RFID Support
  4. Device enable/disable persistence over cold boot
  5. Virtual Key Support in Prefix/Suffix
  6. Performance improvements for MSR
  7. Enable Serial Interface on startup
  8. Support added for Event based Serial reading.
  9. Delays regarding RFID are fixed.
  10. Several Barcode character mapping issues fixed.
make sure some security software is not blocking your access

I have an LS4071 with an RL474 base. The cable has the PS2 Keyboard end. Scanner gets a good scan but no data goes into the computer. Testing with notepad open to receive the scan.


When I connected this scanner (purchased at a great discount through eBay) to my computer using the keyboard wedge (with a ps2 connection - the round connector) I received the error message that my computer could not recognize this external hardware. I went to barcodediscount.com and ordered the usb connector for this scanner as usb connections are usually recognized. The part # for this connector is STI85-0200R. It cost 72.55 with shipping, but I received the scanner at such a wonderful price that I thought I'd chance it and try it with a usb rather than a keyboard wedge connector.
The computer immediately recognized the usb connection, and the usb connector comes with a manual with codes to enable proper scanning, but still no luck getting the data into the computer. So I called Symbol's technical support department. The technician told me to remove the rubber "boot" at the bottom of the hand held scanner (not the scanner base) by pulling on the front of it (where the 2 little round circles are). It's tough to remove, but keep at it. Then gently remove the battery and unplug it, then plug it back in and reattach the base. He said this would reset the battery. Voila!!!! Sucess!!!!

If your scanner's keyboard wedge connection is recognized (a little popup window will say that it is a Symbol barcode scanner and that it is installed and ready to use), try taking the battery out and putting it back in to reset it. Hopefully this will also work for you. Symbol's technical support # is (800) 722-6234.

Fail to configure metrologic usb barcode scanner to use virtual RS232 port interface


First check the com port speed of computer port which you connected scanner .Com port speed should be 9600.
To change com port speed in computer go to computer/properties/device manager.
Select the ports eg com1 .Right click communication port go to properties and select port settings Bits per second should be 9600.
Serial scanner can not be test in word or note pad.you can download the RS232 software from below link and test the scanner

Barcode scanner scans and beeps, but will not put the numbers in the computer


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?
