GE PT878GC Manual De Usuario

April 2004

As discussed in Chapter 2, the PT878GC 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 
PT878GC.  Be sure to position the interface in a way that permits 
transmission between the interface and the infrared sensor on the 
PT878GC, shown in Figure 2-2 on page 2-2.

Table B-1 on the next page 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.
