​BT-100U cash drawer trigger is designed to provide USB interfacing to the cash drawer. This allows the cash drawer, which is previously connected to the POS printer or cash register, to be directly connected to a USB port of the computer. This means through the USB Trigger the cash drawer can be directly connected to the computer when this no printer used in the POS system. The BT-100U USB trigger module uses a virtual serial port driver, making it appear to software like a standard RS232 serial port. This way existing POS software can communicate with the USB cash drawer trigger as though connected to a serial port. A unique serial number is assigned to each USB trigger module and driver software will assign the next available serial port to each device it recognizes(multiple triggers can be used on one computer).
