Sorry if it was unclear.
The saffire pro 40 is connected to the eclipse via the RCA sp/dif connections, with sp/dif cables.
The saffire clock is set to internal and 44.1 sample rate.
The eclipse is set to int 44.1 and digi-in: RCA.
The ext light keeps blinking on the eclipse, so it must now that it is talking to something, although something is wrong.
If i change the clock rate to 48khz on the eclipse, the saffire interface changes from "Locked" to "no lock", so saffire and eclipse communicates, but something is wrong….
Hopes this helps?
