RE: EN 61000-6-2 Table 2.3 inticates signal ports = 30 M +/- 1k v?

Terry, I don't have a copy of EN 61000-6-2, but it sounds similar to the IBM Lightning Surge Susceptibility (LSS) test that we do on our network adapters during development/qualification. We LSS test all products that have: * Cables going outdoors through surge protectors, OR *

You read the table correctly, and it seems to be confusing a lot of people. To go through it logically (I think) The longer the line, the more likely surge energy would be coupled into a cable -- certainly the case for induced lightning transients. Terminated lines shorter than a few meters are
