No deck control help
on May 11, 2007 at 7:16:50 pm

Please help,

We have a Kona2 connected to a G5 2.0 Dual with FCP 5.1.4.

We had to replace the hardrive and reinstall the OS and all of our software. After we installed the kona 2 we can get picture but cannot get deck control.

On of my fellow editors was conviced it was the 422 control cable. That cable runs twenty to thirty feet to the machine room a few bays away into a LAN to nine-pin patch bay. The decks in our machine room are all Sony A500's or M2000.

When the other editor disconnected the long 422 cable from the patch bay and hooked up a portable Panasonic 1200A suddenly he could get deck control.

We have tried two new cables to the machine room but still cannot get deck control.

Has anyone else out there faced this kind of problem? Please help we're stumped.

Thank you.

Editors save hundreds of Hollywood jobs every week.

REPLY - you DO say in the second paragraph, that you hook up a Panasonic 1200A VTR, and have deck control ? Correct ? Guess what - YOU HAVE A BAD CABLE OR BAD PATCH POINT ON YOUR PATCH BAY. You just proved that the Kona is working fine, and that you have RS422 VTR control, but when you run the 30' long RS422 cable to your patch bay, it no longer works. So what are you asking here - can you extend a RS422 VTR control line 30' ? YES YOU CAN. You have a SYSTEMS WIRING PROBLEM, not a Kona RS422 VTR control problem.

This is how you find the problem. One more time, prove to yourself that you can take a SHORT RS422 cable and get VTR control from one of your VTR's. If you have to TAKE THE VTR OUT OF THE RACK IN YOUR MACHINE ROOM - then get off your lazy behind, and DO IT - drag the VTR into your room, and test the VTR with the Kona, NOT USING THE PATCH BAY. If this works, you have a cable problem, or a patch bay problem. You are in Hollywood ? Go to Pacific Radio on LaBrea, and buy a Paladin cable tester, where you can test your 9 pin cables very quickly - it has LED's for each pin, so you can tell if there are any issues.

If in fact, I am mis-reading your comments, and you hooked up a cable between the AJ-HD1200 and one of your other VTR's, and got deck control, but could not get control from your Kona card (is this what happened? - you are not very clear) - uninstall and reinstall your Kona drivers from the http://www.aja.com website, re-select an EASY SETUP, and try again - all of these tests should be done NOT USING YOUR RS422 patch bay in your machine room.
