Wow, I'm sure glad I have the RCX 1.0 with the power jack... I didn't even know the newer ones didn't have it until I started to visit LUGNET...It's something I couldn't live without, not to mention the battery contacts are unreliable... (...) (21 years ago, 21-Aug-03, to lugnet.robotics.rcx)

Wow, that answers a lot of questions, all but one: why is the USB's 'long range' shorter than the Serial's distance? Was my speculation of the available power true? (500mA vs 9v ... not sure if these two measurements can be compared) (...) <snipped> (...) (21 years ago, 21-Aug-03, to lugnet.robotics.rcx)

(...) <snipped long post> Dick, This is a remarkably detailed analysis of the difference between the USB and serial towers. It also contains many useful hints about the preamble bytes and other esoteric things about the LEGO protocol. I have an dea (...) (21 years ago, 21-Aug-03, to lugnet.robotics.rcx)

| | USB vs Serial Tower Response Time
|

Several recent posts have mentioned significantly slower performance of the USB Tower when compared to the serial Tower. After several measurements, I've concluded that the USB Tower is "natively" only slightly slower (~20 milliseconds per message) (...) (21 years ago, 21-Aug-03, to lugnet.robotics.rcx)
