MOTU 896HD and the original 896 clocking together bug
Mon, 02/02/2004 - 22:09
[Edit Feb 2006: The bug which sparked this thread has now been fixed. The continuing discussion on clocking a multiple-MOTU-interface system and maximizing track-count has been broken out to a new thread:
Read on for the bug and the fix....]
This is a confirmed bug for which MOTU is working on a fix. This is with the MOTU FireWire driver version 1.07 for Mac OS X [and was not fixed in version 1.09 on 3/31/04, see below]. I don't know if the PC drivers have this bug.
The newer 896HD and the original 896 (the 896HD's older brother) will only clock together on the "internal" firewire clock if the 896 is first in the physical FireWire chain, AND only if the 896 is the clock master. Individually they each work fine.
If the 896HD is first in the chain, the 896 will not clock off of it. If the 896HD is first in the chain, the original 896 can not be the clock master either. You must put the original 896 first. Another workaround might be to use an external wordclock cable.
My 896HD has ROM 1.01, boot loader 1.0
My 896 has ROM 1.02, hardware v2
I found this bug and confirmed it with a MOTU Senior Technician after I ran MANY trial-and-error tests. We ruled out a hardware malfunction in my particular unit by swapping my 896HD with a new one (which didn't fix the problem). They knew about this bug as of 1/16/04.
Check here (requires free login) to see if they have released a newer driver:
(Another work-around is to use an external wordclock cable.)

There is a bigger problem of synchronization between MOTU896 and MOTU896HD on Windows2000. There is no way to clock them together as described on this page or in MOTU user guide . Newest drivers (3.32) were used without changes. I am very surprised - it seems that only external synchronizer must be used.
Does anybody have the same experience?

Problem solved - dont use VIA FireWire chips.......

Problem of synchronization on W2K was solved, not position on FireWire cable.
Sorry for misunderstanding.
The problem of the position of 896 (must be first on FireWire cable) and 896HD still remains on W2Ks too.
VIA chipsets are used on a lot of PC motherboards. My is MSI K6 Delta FISR.
So I had tried to buy PCI FireWire controller with Texas Instrument chipset and synchronization is working!
