Mesa Ethernet cards need the uspace version of LinuxCNC and a Preempt-RT kernel, Heres. one way to do this:

Manual says
The 7I76Es outputs can drive loads of up to 350 mA.
Is this 350mA each output?
Cheers

Its a bit complex because the driver chips have 8 outputs per chip
and the chip will dissipate too much heat if all outputs are loaded with 350 mA
The individual output limit is 350 mA, but there's also a limit of 1.4A per chip
(8 consecutive outputs)
Also any inductive load that draws more than 60 mA needs a flyback diode
and the chip will dissipate too much heat if all outputs are loaded with 350 mA

Ah, I missed that, Did that, Now I get this. Did I miss something else?

Usually that means that there's a network setup issue of some kind
I would make sure you can ping the card before proceeding
Note that the 192.168.1.121 address is often handy for setup, its usually not a good
choice for a final working system as its liable to overlap a common NAT range
s0 the 10.10.10.10 address is usually better.

Right, so there's a network setup issue
what does
ifconfig -a
print?
(if you are running wheezy you may need /sbin/ifconfig -a)
