 | | 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)

I did more or less that, but I put in a 7809 voltage regulator to make sure that I did no damage to my RCX (wall warts sometimes output as much as 5 volts above the printed voltage).

|

Since I do the whole web-controllable-rover deal with my bot, it tends to go quite a distance. I recently purchased a USB tower from Pitsco and I must say, even WITH the long-range enabled on the control panel, the Serial tower still beats it. In (...)

Somewhere on the LEGO site it says that Serial > USB is not compatable -- If you must, why not just buy a USB IR tower from PITSCO LEGODacta for $30?
