What is a USB drive?

The BT-100U cash drawer trigger is a handy device that allows you to connect a cash drawer directly to your computer via a USB port. This makes it easy to integrate a cash drawer into your system, even if you don’t have a traditional POS printer or cash register. Instead of relying on a serial connection, the BT-100U uses a USB interface to control the drawer, making setup simple and efficient.

One of the key features of the BT-100U is its use of a virtual serial port driver. This means that the device can communicate with your existing POS software as if it were connected via an RS232 serial port. This compatibility ensures that your software will work seamlessly with the USB cash drawer, without requiring any major changes or updates.

Each BT-100U module comes with a unique serial number, which helps the driver software identify and assign the correct serial port to each device. This feature is especially useful if you're using multiple triggers on the same computer, as it ensures that each one is properly recognized and functions correctly. Whether you're running a small retail store or managing a larger point-of-sale system, the BT-100U offers a reliable and flexible solution for controlling your cash drawer through USB.
