Establishing IR Communications with the PM880 C-1

August 2003

Appendix C

Establishing IR Communications

with the PM880

As discussed in Chapter 1, the PM880 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). If your PC does not have an IR dongle, GE

Panametrics recommends the ActiSys ACT-IR220L+ infrared to

RS-232 adapter, which has been tested for compatibility with the

PM880. Be sure to position the interface in a way that permits

transmission between the interface and the infrared sensor on the

PM880, shown in Figure 1-2 on page 1-3.

Table C-1 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.
