I having pcs motherboard, and also lg driver, but the edi pin and also motherboard edi pin is not suitable . . . what about the solution

If I'm interpreting what you are saying correctly it sounds like you are either trying to use the on board network connector on your mother board to connect to a Audio Dock, or you are using the wrong kind of Audio dock together with your PCI or PCIe E-MU card.
Scenario 1: You'll most likely fry the network connector and the Audio dock or if you are really lucky only one of them. Fingers crossed that it's the cheaper of the two that goes.
Scenario 2: The 1616/1616m will only work with the PCIe version of the controller card from E-MU. The 1820/1820m will only work with the PCI version of the controller board.
Again, if you are lucky your hardware is still functional, but I wouldn't bet on it. Combining the wrong controller with the wrong Dock will most likely smell a bit funny after a while.
The PCI version of the controller board provides power to the whole 1820 and considering how hot the docks can get you can bet that it's quite a lot of current that is provided.
I've tried to figure out the pinout of the EDI-connector and there's a 48VDC going into the dock's onboard PWM-regulator. This is apparently generated from a floppy-power connector providing an additional source of 12VDC to the step-up PWM on the controller board.
