AJA LHe Sync Issues while laying to Beta SP, Help!

[Jeremy Garchow]

Just a thought, but what version of the MacPro do you have and have you set it the correct slot? If you have an earlier version of the MacPro (pre 2008) have you setup the PCIe slot configuration properly? Be sure to read the doc carefully if you have a pre2008 MacPro:

1) I do have the termination switch in the “on” position with the 1800. I also have a terminator on the ref loop out. For the LHe, I’m sending ref in and looping it out to a crt monitor with a terminator on the crt monitor. Do all outs from the Horita need to be terminated?

REPLY – you are DOUBLE terminating the Beta 1800. You either use the switch, or the external terminator – NOT BOTH. You basically have no black going to your Beta 1800 because of this. You have dropped the signal level in HALF by double terminating. Do all outputs of the Horita need to be terminated – only the ones that you are using. Send black to the LHe, and terminate there. WHY are you sending reference to the CRT monitor ? This is for RGBS signals. The sync reference to this monitor DOES NOTHING for composite, and component feeds. STOP IT. Take black off the ext ref input or sync input of the monitor NOW !

2) I won’t be in front of the machine until morning but If I remember, when I checked, in the control panel for EXT REF it said 525i 29.97 but didn’t mention anything specifically about “black” I’ll check again when I get in tomorrow.

Well, you let me know.

Hi Bob,
I corrected all my black ref per you instructions. I am still having the issue. I’ve also discovered that After Effects has become extremely unstable when Video Preview uses the Kona. My theory is that a change in the logic board requires me to change the slot that my card is in. I believe in this thread someone mentioned that the early Mac Pro’s use a different slot than the current Mac Pros… hence a new logic board in an old Mac Pro would equate to a new Mac Pro.
If that doesn’t resolve my issue I’ll call Kona
Thanks for your help.
