 | | 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)

Here's another solution worth mentioning: (URL) uses the 3-12V regulated power supply available from Radio Shack (part no. 273-1667): (URL) adapter cable is part no. 273-1742.

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). See (URL) post of mine with more details: (URL) another thread (...) (21 years ago, 15-Aug-03, to lugnet.robotics.rcx)

| | USB Range shorter than Serial!?
|
|
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 (...)

(...) This is the indicator that you are using the datalog. It will fill in more of the circle as you use more of the datalog. It's a very useful debugging aid, as you can tell programs to save values in the datalog, and then download them onto a PC (...) (21 years ago, 14-Aug-03, to lugnet.robotics, lugnet.robotics.rcx)

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? If you have the SDK 2.5, or even the SDK 2.0, it comes with the driver for the USB tower (in the (...) (21 years ago, 14-Aug-03, to lugnet.robotics.rcx, lugnet.robotics.rcx.legos)
