specifying network interface for mesa card

Hello,
I have two network interfaces.
These network inteface have the same range (192.168.1.1/24)
Both interfaces have static ip 
One is for local network
The other is for the mesa card
How to specify the interface used for the mesa card ?
Many thanks for your help.

I would set the Mesa card to a 10.10.10.10 IP address
and set the interface connected to the Mesa card
to say 10.10.10.100
