receiver for an onboard IRDA connector

[<And...@we...>]

Hi,
I just bought an Elitegroup K7SEM with an onbaord IRDA conncetor.
I would like to use the onboard connector instead of the serial port so 
I can fit the receiver inside the housing.
The IRDA connector has the following pinouts:
+5V, IRTX, IRRX, GND and KEY.

It took a look at the ASCII drawing for the receiver at 
http://www.lirc.org/receivers.html and was wandering if I could connect 
the TSOP 1738 directly to the IRDA port. I would then connect pinouts:
3 ---> IRRX
2 ---> 5V
GND ---> GND.

Any suggestions if that could work out and if I still need the R1 
resistor are appreciated,

  André.
