Here is a wiring diagram of the
E-MU 0202.
Note
the funny connector for the Left channel line input. It
will accept an XLR mic level input jack or a 1/4" mono line level phone
plug. A
pair of 1/8"
mono to 1/4" mono
cables are needed to connect from LP-PAN to the EMU. Radio
Shack part #42-2433 is perfect for the job, or you can "roll your own".
You can use stereo plugs at the LP-PAN side if you make your own, but
wire them for mono. On the EMU side, don't use stereo plugs, as they
can get hung up in the funny connector and damage it.
Note also that the E-MU needs USB 2.0 to work at 192 kHz. It is wise to download the latest driver from the E-MU website. Below is a link to the software page. The driver is listed at the top. The latest version as of 9-20-08 is v1.3. When installing the driver, the firmware in the E-MU hardware is also updated. The driver only supports XP, XP64, Vista and Vista 64.

The input pots on the E-MU should be set at or about 11 o'clock to start with, and both set to the same level. Below is a picture of what the PowerSDR Audio Setup tab should look like for this card. You may or may not need the Expert mode selected. On my older PC, setting a latency of 2ms helped the card start reliably. All other settings should be matched exactly as shown, except "Line In Gain", "Mic In Gain" and "Output Voltage" which are meaningless in the context of LP-PAN.

Note: If you plan to feed a second program, like CW Skimmer at the same time as PowerSDR, you will need to select MME drivers in both programs. With the MME driver, latency should be set to 25ms.
If you plan to use CW Skimmer simultaneously with PowerSDR, use the following pictures as a guideline for setting up Skimmer. Your "Audio IF, Hz" setting will be different than mine. A ballpark setting can be found using this formula...
CW Pitch - Global Offset = Audio IF, Hz
CW Pitch is the setting in the K3. It should also be set in PowerSDR and LP-Bridge to match.
Global Offset is the setting in PowerSDR>Setup>SoftRock IF Stage tab. You will need to fine tune it after the initial setting. Use the default CW filter in the K3 when doing this. Make sure the DSP controls are set to NORmal, as they shift the Skimmer display if not.
