MMF Cash Drawer Utility



This added hardware device is simply a "cash box" with a drawer made by MMF attached to  the client computer usually by USB connection. The drawer in the box will open when an SMS user processes a payment and denotes as having received it on a ticket on the payment screen and then saving and printing the ticket.  The type of payment does not matter just that it was received on that ticket.


The cash drawer utility is not a  purchased option available on "view options/update keycode" however

we do sell the actual MMF Cash Drawer hardware and most customers do buy it from us.


The models of the MMF cash drawer are roughly identified as "USB only", "USB without a power supply","USB with serial"  and "manual models". All of them can be used except the manual models. We always sell the USB only with the power supply.

***Do not plug in the cash drawer's USB cable or power cables to the device yet!!!!!*************************

The exact order of how the cables are attached is very important

Plug the power cord into the device first then into the wall. Look to see if LED 5 is red indicating power.

No other LED lights should be on.



Next plug in the USB cable first into the device and then into the computer.


Note: If LED4 comes on at any time the device is not functioning properly
