Subject: Re: [Emc-users] Ethernet!
I have tried Ethernet and it works but if you connect to a switch, hub or
similar with more devices there may of couse be real time problems. Ethernet
is cheap and readily avaiable although Ethercat I expect to be better if the
extra bandwidth is needed.

Actually regular Ethernet GigE is better for bandwidth than Ethercat
(AFAIK EtherCAT is limited to 100 mbit by current hardware)

I still cannot believe that it is possible. I have been testing 2.7+
uspace for a while now. It defiantly opens up options.
Building the latest rt-preemt using peters instructions and .config made
the latency on this laptop much much better. I am running a 2khz servo
thread for a day now.

Realtime communication over Ethernet is just darn awesome!
I would not use a laptop for normal machine running - but for developing
systems - it sure will be nice.
Thanks Peter, Micges, Jeff and everyone else that has made this a reality.
