MMF Multi-Serial Interface
INTRODUCTION
The MMF Multi-Serial Interface enables the cash drawer to be controlled by a serial RS-232 output port in the
following configurations:
• Standard serial dedicated; one cash drawer connected to the PC serial port.
• Serial non-dedicated or daisy chain mode; two cash drawers can be connect ed to the s am e serial port or a
serial peripheral can be connected to the cash drawer using the same serial port.
With both the serial non-dedicated and serial ded icated configurati ons it is possible to select via DIP switches the
following options:
Select a specific or random character to open the cash drawer.
Configure RS-232 settings.
Select the open/close drawer status signal for each cash drawer
Compatible with 12VDC powered serial ports.

DIP Switch settings
To modify the cash drawer settings locate the serial interface module plate on the back of the cash drawer as
shown on Figure 1, remove the two side screws to access the serial PC board and locate the three banks of DIP
switches SW1, SW2 and SW3 as shown in Figure 2.
