I do not see how you could burn any parts or drivers. Even if both ports
would be in active sensor mode and (obviously) out-of sync, the electronics that
connects the port to ADC should handle that as normally the same pin
is used to power up the sensor, which may be disconnected.
Also LEGO would probably put different connectors at the two ends of the cable,
if one could easily burn the brick by connecting two sensor ports (even motors
supposedly have thermal protection when the current is too high - Philo says at
his page that the motors can drive up to 2A
(http://www.philohome.com/motors/motorcomp.htm), but the drivers handle only up
to 1A (Mindstorms HDK), but I would not try too much...and do not quote me
please if you burn your NXT...)
> p.s.: pbLua works fine with bitrates from 9k6 to 921k
Wow. Are there also some devices that connect to the fast port already available
or coming?

| Hello Community, can direct connection of two NXTs (port4) with normal Lego-cables damage any parts or drivers ? Normally I use a special cable (Pins 3,5,6) to use the RS485 communication to another NXT, but some guys told me, they have used the (...) (17 years ago, 5-Aug-07, to lugnet.robotics.nxt)
