  RE: Win2K and IR Tower
 
Have been experiencing this too. I tried changing batteries but it didn't work. Is there a fix somewhere so that W2K won't leave the IR tower's light on? Ralph, kindly inform us if you were successful in replacing the LED. Thanks, Sherwin (...) (24 years ago, 7-May-01, to lugnet.robotics)
 
  RE: Win2K and IR Tower - WinME too?
 
(...) Hmmm, this might get pretty nasty if Win2K is breaking our IR towers. Here's what TLG says about Win2K - it's not supported... (URL) However WinME _is_ supported.. (URL) Are there any WinME users out there and what is the situation with your (...) (24 years ago, 7-May-01, to lugnet.robotics)
 
  Re: Win2K and IR Tower - WinME too?
 
WinME and Win2k are completely different code-trees. WinME is [the last?] fix/update of Windows 98, while Win2k is a rewrite of WinNT. And NT has not been a problem for me, so this was introduced in the NT-to-2k rewrite -- maybe. So this *shouldn't* (...) (24 years ago, 7-May-01, to lugnet.robotics)
 
  Re: Win2K and IR Tower - WinME too?
 
(...) [snip] (...) I have W2K and WinME on my PC at home. Neither of these operating systems drive the green LED on my IR tower continually. At work I have W2K and there, too, it does not continually drive the LED. John Hansen (24 years ago, 7-May-01, to lugnet.robotics)
 
  Re: Win2K and IR Tower - WinME too?
 
(...) If the green LED is on, and data line is held low, no IR is produced by the tower, so it will not harm the LED's. (I keep my tower alive for hours and I can't see any degradation) (...) But I think you use your own serial comm driver instead (...) (24 years ago, 7-May-01, to lugnet.robotics)
 
  Re: Win2K and IR Tower - WinME too?
 
(...) My understanding of the IR tower issue that is being discussed here is that simply plugging the IR tower into a serial port on a machine running W2K is causing the LED to turn on and stay on continuously so long as the PC is operating. I may (...) (24 years ago, 8-May-01, to lugnet.robotics)
 
  RE: Win2K and IR Tower - WinME too?
 
(...) No, just plug the IR tower into a serial port of a PC running Win2K with nothing but the desktop showing. The green LED comes on, but I'm not sure if the IR led is energizer or not... Cheers, Ralph (24 years ago, 8-May-01, to lugnet.robotics)
 
  Re: Win2K and IR Tower - WinME too?
 
(...) Use a video camera to see if any IR is being produced, then you will know that it is damaging the LED's or not. How exactly are they damnaged anyway? They are supposed to last practically forever, right? Andy -- See my Visual Interface for (...) (24 years ago, 8-May-01, to lugnet.robotics)
 
  Re: Win2K and IR Tower - WinME too?
 
(...) I don't have any first hand exprience with this, although a few people have reported that when using NQC on Win2K the IR tower's green LED stays on. I went over the NQC serial code very thoroughly, and I'm confident NQC is closing the serial (...) (24 years ago, 8-May-01, to lugnet.robotics)
 
  Re: Win2K and IR Tower - WinME too?
 
(...) Maybe Lego are deliberately overdriving them in an attempt to get more range - in the sure and certain knowledge that they won't be left turned on for long enough to damage them? (Erm - well - theoretically that is). (24 years ago, 8-May-01, to lugnet.robotics)
 
  Re: Win2K and IR Tower - WinME too?
 
(...) <NERD-SPEAK> Because some people are seeing this and others not, the problem is might be some sort serial port configuration issue involving handshake lines. Which RS232 signal causes the LED to come on (if any)? What type of serial set-up (...) (24 years ago, 8-May-01, to lugnet.robotics)
 
  Re: Win2K and IR Tower - WinME too?
 
(...) My W2K setup (which does NOT cause the IR tower LED to be continuously driven) has flow control set to none. My PC at work is a Dell Dimension XPS T600r. My PC at home is a e-Machines Celeron 600. Neither machine continuously drives the LED (...) (24 years ago, 8-May-01, to lugnet.robotics)
 
  Re: Win2K and IR Tower - WinME too?
 
I've experienced this problem both using nqc and the java serial comm classes. Both are using the microsoft serial port driver, I assume. FWIW, the machine is a Dell Dimension Laptop running Win2k.

  RE: Win2K and IR Tower - WinME too?
 
(...) On my laptop, the green light on the tower comes on as soon as I plug it in. When I run CRT 3.3 (great terminal emulator) the light goes OFF unless I'm actually transmitting! In setting up CRT, it doesn't matter what kind of flow control I'm (...) (24 years ago, 8-May-01, to lugnet.robotics)
 
  Re: Win2K and IR Tower - WinME too?
 
For what it's worth, my desktop W2K machine(generic PII 400)seems to behave just fine. I've tried a couple of different flavors of RcxCC, and the Lego Scout Tool, and they all communicate and then time out (turn off led). Jeff (...) (24 years ago, 8-May-01, to lugnet.robotics)

  Re: Win2K and IR Tower - WinME too?
 
According to the schematics of John Barnes (Serial IR tower), the only way to light the green LED is to sent data or more precise, to hold the TXD line in high state. I've just tested my IR tower (with a general comm driver, which is able to control (...) (24 years ago, 8-May-01, to lugnet.robotics)
