- | USB-VCP is a different method for using a cabled barcode scanner with a windows Computer. The "VCP" stands for Virtual COM Port, which is how a VCP device presents itself to the Windows computer. To do something useful with a barcode scanner presenting itself as a serial port, you must have something listening to the serial port. USB-VCP has one very large advantage over USB-HID, with USB-VCP you have two way communication. This gives you the ability to control the barcode scanner without physically interacting with it. Software intended to be implemented in a manner that leaves the barcode scanner unattended usually places value two way communication. | + | USB-VCP is a different method for using a cabled barcode scanner with a windows Computer. The "VCP" stands for Virtual COM Port, which is how a VCP device presents itself to the Windows computer. To do something useful with a barcode scanner presenting itself as a COM, or serial, port, you must have something listening to the serial port. This enables software to manage the incoming barcode data and ensure that data flow is controlled. A system that uses USB-VCP can also be built to recieve scans from multiple devices at the same time, and still allow the system to remain available for a user. USB-VCP has another advantage over USB-HID: with USB-VCP you have two way communication. This gives you the ability to control the barcode scanner without physically interacting with it. |
