Before you install an iTherm
®
280 Printer into your system, you should verify that the printer is
configured as required by your system. There are four parts to this verification process.
1. Verify that the communications interface card is the correct one.
2. Verify that the cash drawer interface is configured correctly.
3. Verify that the power connection is correct.
4. Verify that the firmware in the printer is configured correctly.

There are several basic types of interface cards, and each has variations. Make sure your
printer has the correct interface card.
Parallel Interface
•
Centronics 36-pin interface
•
25-pin D shell
Serial Interface
•
9-pin D shell interface
•
25-pin D shell interface
USB Interface
•
Standard 4-pin
Ethernet 10-Base-T Adapter
•
Standard Ethernet port connector
802.11b Wireless Interface
•
Wireless interface pre-installed within printer unit
It is easy to distinguish most of the interface cards other than the 25-pin serial and 25-pin
parallel interface cards. To determine what interface is installed, refer to the configuration
receipt shipped with the printer, or enter configuration mode and look at the verification printout.
If a serial interface card is installed, the printout will refer to the RS-232 serial interface. If the
parallel interface card is installed, the printout will refer to the parallel interface.
The interface card on the iTherm
®
280 Printer can be changed in the field.
In most cases, interface cards are interchangeable without altering the printer firmware.
However, you may have to load new firmware and/or a new boot loader before you change the
interface cards. Check with Technical Support for firmware compatibility between interface
cards before ordering.
