Has this been found to work well? I have an application that needs two 7i90hd's, and I will be making a small pcb to connect the 7i90hd's and the 4b. My single 7i90/4b card is working fine.

I have not tried it. Cabling and signal integrity might be an issue. Peter Wallace Mesa Electronics _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
