--> Therefore exists a new TD400 device.

The BDA devices have been obsolete for a long time. They can no longer be supported because of security issues with the embedded Java that is contained in the BDA. I can honestly not recall whether Powerconfig supported the BDA.

We have had good success both with the TD400 and using a COM16 or COM35 module as an interface between the ETU and Powerconfig. The attached file shows how to use a COM16 but using a COM35 works exactly the same way.
