All,
I have a RIS 1.5 set installed on windows 98 PC . I have got some
trouble with IR Tower and RCX communication . First the IR tower was
not detected : using the bios setup menu from start up I succeeded in
setting correctly the serial COM2 (disabling COM1 & LPT ports).
It was working fine : I downloaded firmware and a short program. But
now it doesnot work : the IR tower is detected and looks fine but does
not communicate to the RCX . Here is the log file I got after testing
the IR tower and RCX brick:

There is something wrong with the RCX. I made myself the serial cable
according to information got from RCX internals pages. I am afraid the
IR tower has been damaged !!
Anybody to help me ?
Thanks a lot
Bruno

I hate to ask you this, but how is the 9 volt battery in the tower? Is the
light turning on when your attempting to transmit?

... the battery is new ! I made another test and I realized the cable
was not safe (wrong contact between pins and wires, I think) that can
explain the wrong communication. I have to check the connector
welding...hoping the IR tower is not damaged

I could make a pin to pin drawing if you need it. Seems that a wire may have
come loose to cause this problem. Let me know if you need any information.

Please log in for more thread options here is the drawing of my cable ( from
http://graphics.stanford.edu/~kekoa/rcx/) :
Pin To Name Description
2 3 RD Receive Data
3 2 TD Transmit Data
5 5 SG Signal Ground
7 8 RTS Ready To Send
8 7 CTS Clear To Send
Pin 4 connects to pin 4 but is unused; pins 1, 6, and 9 have no
connection.
is it right ?
I used HyperTerminal to test the IR tower : if works fine but I don't
see the led lighting (according to the lego mindstorm trouble shooting
guide, it shoud light while typing !).
