API reference for UniPay 1.5
Connecting to UniPay 1.5

The UniPay 1.5 connects through USB.

Connect with USB:

The UniPay 1.5 uses USB-HID (Human Interface Device) and does not need any vendor-specific drivers. Simply by plugging into an available USB port makes it available for SDK connectivity. The SDK will automatically scan/detect the UniPay 1.5 when any singleton instance command is executed. For example:

String fw = null;
IDT_UniPayI_V.SharedController.device_getFirmwareVersion(ref fw);

When the SharedController is accessed for the first time, the SDK scans the USB bus for the specific VID/PID of the UniPay 1.5. If found, it will execute the command.
