96Khz Master/Slave Sync

I have an XITE-1 64 Bit setup, slaved to a second SCOPE PCI Machine.
I note that changing the samplerate on the master (PCI Card) the slave follows and syncs to all sameplerates except 96KHz.
When the PCI Card is set to 96KHz the XITE stays at 48KHz?
Is this a bug or am I missing something?
- XITE-1 - SCOPE 5.1 2709 64Bit, Win 7 Pro 64 Bit
- PCI (Pulsar 2 + Luna) - SCOPE 5.1 2709 32 Bit, Win 7 Pro 32 Bit.

I believe you are using ADAT as clocking interface? Not AES/EBU nor wordclock.

If you are using ADAT (Toslink) cables for sync reference: are you using 1 or 2 Toslink cables?
48khz is max sample rate per Toslink cable.

Thank you - thats it!
I am using ADAT TOS link cables.

It should be possible to sync 96khz wordclock over 2 Toslink cables (2 x 48khz) using SMUX.

ADAT lightpipe does not send any information about the data rate. ADAT 48 kHz and 96 kHz works at the same datarate. That is why you get only half as many channels when working in 96 kHz. You need to tell the receiving device that it should treat the data as 4 channels of 96 kHz. In Scope, you do this by using the SMUX in- and output modules instead of the ADAT modules. Also in the sync setting, you should set Scope to slave to a SMUX source - NOT an ADAT source
