BARCODE SCANNER OPOS DRIVER
January 19, 2020 | by admin
You do not need any pre-amble characters. NET developers to interract with peripherals typically found in the retail environment attached to Point of Sale, Self-Checkout, Kiosk, and ATM devices such as barcode scanners, magnetic stripe readers, cash drawers, etc. Sunday, April 1, 5: I believe your best bet would be to setup logical names for each device in the configuration tool for your scanner driver. Removing the active scanner, would enable the second scanner to work.

I am suspecting a possible resource handling issue in C. Shouldn’t they have something like a unique-per-scanner ID just like network cards have MAC addresses? Thursday, April 5, 7: I believe your best bet would be to setup logical names for each device in the configuration tool for your scanner scxnner.
Sunday, April 1, 6: They would all have the same PnP ID so it is not easy to know bzrcode one is which.

Can you guys perhaps suggest a better approach? Monday, April 2, But this only works with two scanners.
You may call serialPort. Can you please link me to an example of a configuration?
I think there was a tool for it, but I remember it never worked. Saturday, March 31, 3: It is still not clear to me whether the items appearing in the getDevices list are device classes or devices which exists physically. Sign in to vote. I doubt that would work. Select the OPOS Tab, and the Scanner tab, click on Use this device and select the identity that was setup in the configuration of the manufactures setup.
Either the port does not exist, or zcanner other device is already using it. The preferred method is to open the Windward Point of Sale Device Manager in the Windows Tooltray usually in the bottom right of your screen.
This method will enable the scanner operate even when System Five does not have keyboard focus, or if there is a dialog window open. Maybe the handle for the resource does not expire when I use Closewhereas when Putty closes, the whole process is destroyed which probably triggers resource dealocation as well.
You will have to use the manufactures software to configure the scanner. As Woodchux pointed out, you have to setup unique logical IDs for each device. I know that with Service Objects one can create a configuration file and associate a SO with a hardware ID this would imply that I would have to deploy the config file on every machine that I’m running the application on, so it’s not very suitable; also what happens if we decide to switch to a different scanner in the future.
You can remove the DLL out of the path so it is not confusing with the other devices.
Well, the thing is that I’ve managed to communicate with the scanner. I also tried creating two scanner instances using the same device type. Monday, April 9, 7: There will be around 6 of them.
Connected two identical scanners.

Thanks for your reply Woodchuk. Since you said you worked with a Datalogic device in the past, do you remember whether you were able to identify such varcode tool? Thanks for following this thread, Sean. From crashes leading to open ports to being forced to assign a name for each of my scanner manually. Removing the active scanner, would enable the second scanner to work.
