I could, but I need to get hold of Ts and terminators. System has mostly been OK daisy-chaining so far. I've read elsewhere that this is OK? Might grab some Ts and terminators though.

...but I've just noticed something else interesting.

I rebooted. Now Card 1 (Master) is "-- : -- : --" and the other 2 say "Card 1".

This might tie into my other post and other problem on noise on Card 2. On first boot, Card 2 was "-- : -- : --" and showed noise until the reboot. Now it's showing "Card 1" under Time Code and is working OK.

Is this maybe a card initialisation order issue, solved by a reboot!? Bug in the driver initialisation even!?

Thanks. This is a bit more complex than a motherboard though.

It's the 3 HDSPe cards in a Sonnet Thunderbolt chassis. When it works, it's a great system - 24 analogue inputs and 24 analogue outputs, plus the SPDIFs.

It's worth it for me to go through the reboot process when recording. However, if there was a possible fix, that'd be great too.

However, I am now wondering if I should order some BNC T connectors and a couple of terminators.

Sadly, it doesn't fix the issue. I have some BNC T connectors and terminators on the way though.

If I understand correctly, Wordclock out doesn't need termination, but the end of the daisy-chain through to the last unit does need terminating. ...but I'm getting a few spares, so can config as necessary.

Edit: Actually, I might have been wrong on the above. It may actually be working! Shutdown and reboot worked this time. If I can shut-down overnight and it still works, then I might be on to a winning formula. Thanks!
