(...) You are the second person to report something like this, so there must be something wrong somewhere. I will take a closer look at this when I get a chance. I am busy until Tuesday though. I know I will forget, so keep e-mailing me until I fix (...) (23 years ago, 26-May-01, to lugnet.robotics.rcx.legos)

(...) This isn't true at all. The tower converts an RS-232 serial transmission directly into IR and vice-versa. It is a pretty standard protocol. -Kekoa (23 years ago, 26-May-01, to lugnet.robotics.rcx, lugnet.robotics, lugnet.off-topic.geek)

(...) You can't really do what you are trying to do. The tower is designed to operate in request-reply mode. It sends a request, waits a few seconds, receives a reply during that time, then turns off. The idle state of the tower is off, and (...)

Even more interesting.... I've also just replaced the IRED I replaced a few hours ago in my RCX :-( This time, I'm putting a limiting resistor between the IREDs in the RCX to keep the current within limits. The following is pure conjecture on my (...) (23 years ago, 26-May-01, to lugnet.robotics.rcx)

(...) Actually, there's a regulator on the Tower that takes the voltage for the digital side to +5 and keeps it there. The capacitor is only rated for 10V. The higher voltage will allow higher current through the IREDs as they are connected right to (...) (23 years ago, 26-May-01, to lugnet.robotics.rcx)

(...) I'm pretty sure I know your problem to your number 2... The IR Tower has no protection against higher power. Running an unregulated power source into the IR tower is not a good idea! Use a 9v regulator package (The little 3 prong packages with (...) (23 years ago, 26-May-01, to lugnet.robotics.rcx)

That being said, I think that now is the time to relate some experiences I've had over the past couple of months with my RCX and IR tower - and it boils (...)

(...) Not really -- the tower uses its own proprietary communcations format. It's similar enough to that used by remote controls that learning remotes can pick up the signals, but I haven't heard of anyone going the other way around.

I know this may be a bit off topic, but didn't know where else to post, I own an IR tower and remote control, and was wondering if it is possible to use the IR tower for other things. eg using PC + tower to control stereo/TV, or using IR remote to (...)
