Justin –
I have no idea of how you will get thru running an AVID product with no training. It’s more than just plugging in the cables.The correct adaptor for your MAC G5 is the Keyspan USA-28x. This will give you 2 serial ports in the old MAC serial style (like on old MAC Quadra 950 computers). From there, you need an additional cable that AVID usually supplies to go from this connector on the Keyspan to a 9 pin male RS422 connection. You can also get this cable from Pipeline, and Addenda Electronics.
Once you do this, you must load in the keyspan software, enable the ports in the “network” portion of the system preferences in OS-X, and then in the Media Composer application, go to “settings”, select DECK CONFIG, and select the keyspan port for your VTR control. In this menu, you can also choose the VTR model that you have. This can also be done by “autoconfigure”.
How you will figure all this stuff out (and other stuff) without a manual, or training, is beyond me.

I just read a FANTASTIC review on http://www.barefeats on this subject, that I will copy below, WITHOUT permission from Barefeats (hope this is not an issue). To summarize, the Express card that goes in the MAC Book Pro does NOT have the bandwidth for uncompressed HD, even with 5 drives –
Hope I’m not in trouble for copying this –
bob ZelinThough the theoretical bandwidth of an ExpressCard is 256MB/s, the current speed limit of all ExpressCards is about HALF of that when used with a RAID set no matter how many drives are connected. This is due to the fact that all current ExpressCard products use the Silicon Image 3132 chip set and, for some reason, that’s as fast as it can go. Actually, the same is true of when the 3132 chipset is used in a PCIe SATA host adapter for the Mac Pro.
We ran a five bay PM enclosure (filled with Hitachi 7K500s) on our Mac Pro with a using the Sonnet E4P host adapter (based on a Marvell chipset). We got 240MB/s READ, 216MB/s WRITE. We moved the same enclosure to a MacBook Pro with an ExpressCard SATA host adapter (based on the Silicon Image 3132 chipset): 125MB/s READ, 111MB/s WRITE. Hopefully future improvements in the chipset and/or firmware will overcome this speed limit and MacBook Pro owners can experience true joy when they connect a four or five drive array to their ExpressCard.

why, can you get me out of here ?
(I’ll be in beautiful Tempe in April 2007, before NAB, so you better look out !).

The 5 drive Cal Digit S2VR is faster than the Sonnet. But if you already own a sonnet, you can add a second chassis, stripe all 10 drives together RAID 0, and do uncompressed HD as well. The Cal Digit is fantastic, however.

of course not. The limiting factor is your drive array speed, and the internal drive will NOT do uncompressed HD. Currently, the minimum requirement for uncompressed HD is 5 SATA drives in a box like the Cal-Digit, so it will be YEARS before the speed of a single drive in a laptop is fast enough for uncompressed HD.
If you think you are going out on a shoot with a Sony CineAlta, and a laptop, and will record 1080i uncompressed on a laptop, you are dreaming.
No ad implies that this will work.

Bottom line –
you use the original Kona cables with your Kona card (no KL box). You run AJA Kona Control Panel – you can see the test patterns, but you can’t see the Beta thru the AJA Kona using AJA Kona Control PAnel, and you are sure that the cables are good.You have reloaded the AJA drivers.
You probably have a bad Kona card.

I reread your original post – you said that you DID try to bypass the breakout box with the original Kona cable supplied with the Kona card (using the BNC’s supplied by AJA). If you cannot get your Beta VTR to pass thru the Kona card, I urge you to RELOAD the AJA Kona drivers from the AJA website, and try all over again, using only AJA Kona Control Panel.
If this still fails – may I URGE YOU to try this. PLEASE PLEASE PLEASE take one BNC cable, plug one end into the Y output of your Beta VTR, and plug the other end of the BNC into your TV monitor composite input. Play a tape. You should see a black and white image. If you do not, this means that the Y output of your Beta VTR is not working. If it does play a black and white image, you certainly may have a defective Kona card.

ok –
you said that you COULD get the Kona Control panel test patterns on your TV – am I correct ? This means that your Kona card can output to the TV monitor (am I correct ?).One more time – take the beta analog component output (with 3 cables) into the AJA KL box (your breakout box) inputs. Make sure the INPUT tab of the control panel is ANALOG COMPONENT BETACAM – when you play a beta tape, you should see a picture.
If you do not, take the cables that came with the Kona LHe card, and disconnect your KL box, and use the break out cable they gave you. Try the same test, using the cables that come from AJA on that break out cable.
If this does not work, let me know.If this does not work (with the original AJA Kona breakout cable – NOT using the AJA KL box – you should RELOAD your Kona drivers from the AJA website, and try again. If this still fails (and you are ABSOLUTELY SURE that your BNC video cables are ok), you may have a bad Kona card.

as I said in my post, I don’t give a CRAP about DVCPro50 right now, or Final Cut Pro. I want you do test your Kona Card with the AJA Kona Control Panel.
I will not assist you any further until you find, and launch AJA Kona Control Panel, and test to see if your Beta machine is going thru your AJA Kona card.Please let me know.
