Hello:
I just purchased a Viessmann Coupler #5302. Unfortunately it came without the LSB cable. I purchased a similar cable to this on Amazon.com

The coupler LED flashes continuously and it turns on the red led on my Commander, when connected. So I assume this cable is incompatible to a Viessmann LSB cable. So what is the difference?
Thanks
