Appendix C – Using the IrDA
®
Interface
Overview
In addition to the standard Serial interface, your DP-550 may be equipped with an optional IrDA
®
interface. To
determine if this interface is installed in your printer, you may look at the model description on the serial
number label on the back of the printer. You may also refer to “
Performing A Printer Self Test” on Page 7.
The IrDA interface uses infrared light to provide a cable free, short range interface. Since the communications
medium is light, it is “line-of-sight” and requires that the interfaces on the printer and the host device be aligned
with, or pointed at, each other. The printer’s transmitter and receiver are located behind an “IrDA Window” as
indicated in
Figure 13.
Whenever a host computer has established a connection with the printer, the Wireless Indicator will
illuminate.
Note: The printer’s IrDA implementation makes use of IrCOMM rather than IrLPT. As a result, some host
systems will require that the printer connection be established using a “COM” port rather than
selecting “IrDA”. In most PDA’s this will be “COM3”.

Selecting the IrDA
®
Interface
In order to use the IrDA interface, it must be the currently “selected” interface. To determine if the IrDA
interface or the Serial interface is selected, you may either perform a printer self test as described on page
7, or
you may perform the following procedure to determine if it is selected and then select it if necessary.
1. Make sure the printer is powered on.
2. Press the
Enter Button. If the IrDA interface is currently selected, the following will be displayed
and you may skip the next step.
