Bar code reader connection

Navigation:  Cash register preparation > Connecting peripherals >
clip0726The barcode scanner connects to the touch cash register via a standard USB port. No special settings are required once the reader is connected to the cash register. The Android operating system just displays a dialog to select the keyboard layout after connecting the reader. This is because the reader is detected by the system as a standard keyboard. This dialog can be overridden by setting the keyboard layout once.

The Dotypos supports the connection of standard (manual) barcode readers and also omnidirectional readers, where it is not necessary to point the beam precisely at the barcode. The button on the top of the omnidirectional readers switches between scanning 1D and 2D codes, i.e. barcode or QR code.

In principle, any barcode reader that emulates a keyboard should work with the Dotypos. That is, Android detects it as a new keyboard when connected and displays a dialog for keyboard selection. The English keyboard layout should always be selected, otherwise the reader will not work properly, see the procedure below.

If you are using an 8" cash register with the supplied Y cable and reader, you must still set the correct USB connection mode before connecting the reader. The omnidirectional reader also works with a 10" cash register via micro USB reduction.

The DOTPO0501 touch cash register (Sunmi V2) with an integrated printer allows bar codes to be loaded directly using a built-in camera, more information can be found in this chapter.

For reading bar codes, Dotypos uses the library ZXing and supports the following:

From the layout list select English (United Kingdom). Since the reader acts as a normal keyboard, you have to set the English layout. If the Czech layout is set, Czech characters with diacritics will be inserted after scanning the bar code. Therefore, any search for products will not work. The Android system will remember the chosen layout and the next time you connect the reader the notification about keyboard layout will no longer be displayed.

-Connecting an reader to a 8" touch cash register

The 8" touch cash register allows externally fed peripherals to be connected via a special Y cable. At present you can connect the bar code reader to the cash register via this connection. To ensure this connection functions properly in the Android system settings, go to the section Security and deactivate the option Vypnout OTG ACA. After that you can connect the power supply and the reader via the Y cable.

Connect the Y cable to the cash register’s micro USB port. Connect the power supply adapter to the USB connector (male) on the longer side of the cable. Connect the bar code reader to the other USB connector (female) on the shorter side of the cable. The special Y cable allows the cash register to be powered continuously.
