I could not get the new IR train to control the PF receivers either at full on, or with PWM. My IR train, and PF gear are 100% incompatible. (...)

(...) Okay, thanks. I can get 'Single output Mode' to work now. 'Single pin Mode' may be working too, but I'm not sure what to expect from it. I would expect setting either C1 or C2 would set them to 9V and run a motor forwards or backwards. Setting (...)

For instance, tunnels and large layout out of line-of-sight on the RC should now be possible. (...) (17 years ago, 26-Jan-08, to lugnet.technic, lugnet.trains, lugnet.robotics)

Now you can use your RCX to control LEGO Power Functions. That's right the RCX can act as a PF remote control but it can do something that the PF remote can't do yet. The RCX can do PWM with your PF reciever moduals. You do not need to install (...) (17 years ago, 25-Jan-08, to lugnet.general, lugnet.technic, lugnet.trains, lugnet.robotics, lugnet.announce, FTX) !
