Cash drawers are usually connected to the receipt printer. As soon as the POS software like till sysytem for bakery store sends a specific control signal to the printer, the printer sends an opening pulse to the cash drawer in order to open it. If the cash drawer is used without a printer, this is not an option. In such cases, you will need the opening module 8005.
The Glancetron 8005 cash drawer opener is connected to the serial or USB interface of the cash desk PC. Then the POS software sends the control signal to the 8005 instead of sending it to a receipt printer. The cash drawer will open after it has received an opening pulse from the 8005.

The adaptor is installed in a slot plate space on the back side of the PC (without occupying a slot internally).
