Tunze 6105 with profilux 3 and expansion box

[Chinaexpat]

I just got my Profilux 3 and Expansion Box.

I constantly get communication errors and have to disconnect my USB cable in order to close the Profilux software, and tehn restart it, is this normal?

What I am trying to do is to have 2 pumps alternate, creating a pulsing motion. I had this with my Tunze 7095 Controller but want to use the Profilux to control them instead.

I have L13L14 connected to a Y-slitter (on my expansion box) and from the Y-Splitter one cable going to Tunze pump #1 and the other cable out of the splitter going to Tunze pump #2.

The display only shows Pu.1 0% nothing for pump 2 although and one pump is running!

I am only using Group 1 and have both pumps set up in Group 1.
setting "Permanent Opposite"
Pause Duration 2 minutes.
Count of pumps in Group 1 = 2
No waves

Any help is appreciated!

For the USB issue please check the following link: http://www.aquariumcomputer.com/Forum/showthread.php?634-Connection-with-USB-please-read-first!
Concerning the pumps, I guess you have assigned L13 to Current pump 1 and L14 to Current pump 2 resp. the other way round?
Please activate the function "no waves" to "sinus waves" and check if it works then.
