Cash Drawer

Interface Description

®
The iTherm 280 Printer supports a single cash drawer with status. The driver in the
printer is capable of supplying 24 V DC at up to 1.5 amps for up to 250 milliseconds. The
®
iTherm 280 Printer defines cash drawer closed as switch open. If the drawer is
disconnected, it will be viewed by the printer as closed. Since the printer does not act on
the cash drawer status, the application can interpret cash drawer status any way it
wants.

Figure 2 Cash Drawer Pin Definitions

The cash drawer can be configured for one of three configurations; Ithaca, Epson, or
Star. The Main Controller PCB has three (3) six-pin headers, one each configuration.
The cash drawer harness is identical, and is plugged into the appropriate header at time
of factory build. The header position defines the configuration of the cash drawer. This
design allows for changing the cash drawer in the field by a trained technician. Refer to
the markups on the board when determining where the harness should be installed to
work in the three different configurations.
