With the SSC connected to the hub, set the jumper on. Turn on the power and using the SS Utility transmit the new channel. All of the lights on the SSC should flash white. Turn off power, set the jumper back to off. Now when you reapply power, the channel should be set. You can also just connect and disconnect the Cat5 vs. turning off the power, but I prefer no to connect / disconnect Cat5 while the hub is on.
You can use either the Etherdongle or PixelNet dongle to program the SSCs. You cannot use the conductor or the Lynx DMX dongle. I believe the green light should be on, but with PixelNet may not be flashing like it does when using DMX.
