Appendix F. Establishing IR Communications
As discussed in Chapter 2, the PT878 includes an infrared transceiver for
communication with IR products that comply with the IrDA protocol.
However, you must also be sure that the operating system of your personal
computer offers IrDA compatibility and either a built-in IR port (available
on most laptops) or an IR dongle (IR to RS232 adapter for PCs without a
built-in IR port). Be sure to position the interface in a way that permits
transmission between the interface and the infrared sensor on the PT878,
shown in Figure 2 on page 6.

Note:
The dongle connection is RS232. The configuration options are either
RS232 or IRDa. Selecting the RS232 does not link the meter to the
dongle. IrDa must be selected for the link to work.

Table 10 below lists IrDA compatibility for various past and current
Microsoft Windows operating systems. IrCOMM is an infrared standard
supported by Microsoft, while OBEX is a newer infrared standard which
allows more straightforward use and faster file transfers, while tolerating IR
interruptions better.
