Mauro,

PCMCIA serial port cards are available (just search the net for them).  Here
is one such card that has two serial ports:
http://www.tronlink.com/serialio.htm

Since those cards aren't too cheap but old 14.4/28.8kbps PCMCIA modems are,
perhaps making your own will suffice:
http://www.netcomuk.co.uk/~wwl/diyserial.html

The particular rs232 driver chip that was used is a Maxim 241.  For those
that don't know, Maxim (http://www.maxim-ic.com) will send you samples of
many of their components for free (the maxim241 chip is one of them).

Hope this helps!
Rob

Unfortunatelly I can't buy that at Brazil. I want to buy a RIS 2.0 when
possible but if I buy it here it would cost over US$300!
I prefer to buy the whole set than individual pieces. It is more cost
effective.

Meanwhile I'm using my desktop computer. But since I usually don't run the
robot in the same place the desktop is, using the notebook would allow me • to
correct programs faster...

By the way, does the USB tower needs a 9V battery?
If it could use the USB port as supply it could be on all the time. That
would be useful for applications where the RCX needs to talk with a PC all
the time.

tks,
Mauro Vianna

I solved that problem before I encountered it altogether.  I just bought • the
usb IR tower from Lego Dacta www.pldstore.com
and the RIS 2.0 upgrade kit from Lego S@H.

cost me about $40 US, but that USB/Serial adapter was twice that when I • went
looking for one...

Hi, all

I have a problem trying to connect a serial IR tower to my notebook. • The
notebook has no serial port, so I'm using an USB-serial adapter. • Although
this adapter worked for another device, it seens it is not working • properly
with the IR tower.
The funny part is that the IR tower green LED is on as if it was • working.
but I can't detect the Brick using Brickcc. :(

Did anybody faced (and solved) this problem?

Thanks,
Mauro Vianna
