Default Clocking to an Apogee Big Ben one 192 and a legacy

Hi Folks,

sorry bout the pretty old topic, but I tried so hard (searchin the answerbase too!), and I surrender:
Could anyone kindly give me a final solution?

I'm clocking to an Apogee BB one Digi 192, and a legacy interface (888/24), on HD3.
Since I read on this precious (!!!) forum that :

1) interfaces must be correctly terminated

2) 192 (when used with 888) must be set to "internal" from protools even if it's clocked to another device

I set like that, but I discovered I was not using (since a lot of time, poor stupid me!!!) the Big Ben clock, but the 192's...

Then I tried to clock the 192 to the channel 6 (256 x) of the BB and the 888 directly as a slave from the 192's clock out, but as I turn on Protools a splash says I can't do like that and it resets to internal.

Same thing if I try to slave 192 to BB's 6 out and the 888 to 5 out (256 x).

The only way it seems to work is connecting the 192 to BB's clock out 1 and 888 to BB's clock out 6 (256 x).
The bad thing is that on Big Ben display the 888 is not resulting terminated!
Is there a risk of damage?
Is this the correct way?

Please, give me some of your precious time and help me!

P.S. Sorry for my weak english...

I have a 192 and a 1622 IO slaved to Big Ben.

I have the 192 connected to 6 and the 1622 hooked to the superclock out (maybe 5???).

On the front panel of Big Ben, the 192 termination light is lit green. The 1622 light is not lit at all.

That is not the same thing as being lit up red, which means improper (or is it no) termination.

I tried to buy a terminator for the 1622, but when attached correctly, it made the 1622 terminator light turn red on Big Ben.

Long story short. For me, I've never seen 2 green lights on the front of Big Ben. Just the one for the 192. A long time ago I talked to Apogee, and they said that is ok.

Maybe I am wrong, but I've never had an issue. Call them. If I'm wrong, I'd love to know.

Thanks for the answer mate,

but let me know:
why do you connect the 192 to the super clock out (I'm pretty sure that both 5 & 6 are 256 x)?

Is it better than normal clock, let's say, 1?
