Adat I/O Problem

Conqueror's Reign · Post by **Conqueror's Reign** » Wed Jul 25, 2007 2:06 am

Hello Z,
I need your help. I have 3 cards a pro with 24 adat i/o plate, a project classic i/o and a luna (3 dsp). I followed the suggestions from the forums and made sure sfp was uninstalled rebooted system without cards. Then installed cards with s/tdm connecting to each card and let windows install the drivers first before installing scope 4.0. I modified the cset.ini so that the larger pro card is 1 project card is 2 and luna is 3. All dsp and hardware/software I/O are present in the menus. All work except for the adat I/O on the pro card. When i connect the adat it shows up as active in the samplerate box but the audio that comes thru it is chopped like a rapid tapping sound.

I removed the module from the project and replaced it but still get the same chopped signal.
All the other I/O on the other two cards work it is only the adats on the pro card.

Is it neccersary to rebuild all the projects within SFP or just the default one?
Does anyone know what would cause the signal to playback that way or had this problem?

Is adat working ok on your project card?

that sounds like a bad master/slave relationship....

Yes the adat on the project card works without problem.

The Priority is set normal for SFP

Im not sure how to disable the bad i/o

How do you make sure which card is truly master and slave?

ok made a discovery when adat is connected to the project card set to master audio passes thru wihout problem, the adat set to master on the pro card audio is chopped up no matter which of the 3 adat ins i use.

When i set the pro card to slave audio comes thru no chopping and without problem thru all 3 adat ins. The project card still passes the audio in eithier slave or master without problem.

Why would the pro card not act in the same way as the project card and work as slave or master?

you're making whatever is on the procard's adat connectors master, not the card. when scope is master, it's master for BOTH cards. otherwise, any of the adat ports or sp/dif is master. many devices can only be master, what's connected to the pro card's adat connectors? what is it set to?

the card that is sending the signal to the scope adat's is a rme 9652 and as far as i can tell in the rme settings it is set to automatically adjust to master or slave depending on the signal, it has an auto sync function. I dont see anything to set master or slave for the rme but if the project card works in slave or master whats the difference with the scope card? How can the project card work in eithier mode and not the scope card?

just my guess based on the info i have..

it depends on the rest of the system. i suspect that auto means that if it doesn't see clock within a period of time, it defaults to master. if the scope system is slave to the other card's i/o and it doesn't receive sync before the RME gives up, you'll get two masters.

auto is bad here. you want to make decisions for the gear to assure yourself of one master and several slaves. what's bad for humanity is good for your DAW...

if you can't choose, then perhaps activating the RME last will solve the problem...

you want the gear working for you, not vice versa, so you must be able to tell it what to do and have it do it....

seriously, can't you set it to master or slave as you require?

I don't leave my RME as autosync, I just set it to Master and Scope to slave always. However my Scope system is my secondary system so I'm more likely to be using the RME without the scope than vice versa (which might potentially cause issues if the RME is master and sitting idle).

Thanks guys i will work on it and let you know how it turned out

ok it seems that i will have to set the scope system to slave if i want to use the adat i/o on the pro card. The rme card only has 3 options to set the card autosync, master, wordclock no option of setting it to slave. Input into the project card as master and rme in autosync mode works fine and would be the workaround if i want to keep the scope system as master with that setup but with the adat input routed to the pro card its just not happening, audio in scope by way of the pro card has to be slaved to the rme. This isnt really a major problem it was more curiosity how one set of inputs could work differently from another in the same system with both cards linked by stdm and both being sent a signal from the rme without any changes.
So slave it is, thanks again for all of your input
