Hi Ronald,
I used to have a serial port cash drawer but I think the connector is not working well as sometimes it doesn't want to open at all. So the new cash drawer is not serial port or usb port. Is RJ11 port (which looks like a telephone connector) which connects to my citizen CT-S651 printer. I set the printer and equipment/ open connected to printer but it did not open. Was my setting wrong? or do I need to set at my printer ?? Pls help.
Confused.
