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. Below is a link to a copy of the last release version of the E-MU USB driver. Warning! When installing this driver, the control panel is also updated as well as the firmware in the E-MU hardware. The new firmware may be incompatible with some E-MU 0202s. Creative is aware of this. The driver only supports XP, XP64, Vista and Vista 64. It should work with E-MU 0202 and Tracker Pre. I don't think it will work with the 0204.

There is also a beta for Windows 7, 32- and 64-bit. This should only be used only with Windows 7 for E-MU 0202, 0204, Tracker Pre, etc. This is driver only. It is known to have some bugs...

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.

E-MU 0202/0204 Installation

Install E-MU 0202/0204 USB sound card per the material that was supplied with the card.

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" (3.5mm) 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. The two “ground lift” switches on the bottom of the E-MU should always be in the same position, preferably in the OFF position. This will enhance the sound card’s ability to reject hum and noise pickup due to ground loops.

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 E-MU 0202 sound card page on the TelePost webite. It shows proper PowerSDR/IF sound card settings for the 0202, and has a link to the latest E-MU driver. Settings for NaP3 can be found on the NaP3 page.

Important under Windows 7 or Vista : If you are using Windows 7, and wish to use the E-MU 0204 with programs that don't support the ASIO driver, such as CW-Skimmer, you will need to set up the E-MU in the "Recording Devices" tab of the Windows sound mixer. Please right click on the speaker icon of the task-bar: a pop-up menu will appear. Select the Recording devices submenu and a new Sound form will pop up.  Click on the recording device you are using, and then click on the Properties button. Click the Advanced tab and under Default Format, select the highest sample rate and resolution that you will use with your sound card (typically 24bits/192000Hz for an EMU202, EMU1212m and Quartet); close the sound form. Now, please configure your sound card using the utility provided with your driver (i.e the EMU or Quartet control panel) and configure it for the same settings. Click on the Levels tab abd set the recording level to 2.

It is wise to never power down the E-MU independently of the PC, since it will probably try to start back up with 48 kHz sampling rate. It draws very little power, and can be left on all the time. Make sure that the power management in the PC doesn’t power down the USB port when the PC is asleep or standby.

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.
