The splash screen in DVC1 is saying DVC2 Gold.
Yes it does have a socket for a power adapter.
I've download the latest drivers, installed them.
Downloaded the firmware upgrade kits and tryed to run them all, but the start buttons are always greyed out.
Hmmm, very strange. I have one of the first DVC2 Golds and that has 2 xlr sockets (in/out).
Alos I got something wrong the DVC1 Gold that I have has only 1 XLR socket, not 2 as stated.
Maybe yours is a DVC1 Gold that has been upgraded or a pre- 2 XLR version of DVC2 Gold ??????
When you download the firmware.zip and have unpacked it.
You should find 3 folders, try each of them as it might a suidi-5 interface or a suidi-6 interface.
Other than that you will have to see if you can get Daslight to help you.
