Replacement USB-RS422 converter for VectrinoII

Posted by Dhanushka Kularatne at May 15. 2017


The USB-RSS422 converter that came with our vectrinoII profiler broke down. One of the pins on the usb connector had broken off from the circuit inside the converter.

We tried using an off the shelf USB-RS422 converters instead. However, the profiler is not being detected with this converter.

The Altronix AL310 converter thats shipped with the profiler is not commercially available and Nortek does not sell them as separate units.

Has anyone else faced this problem and if so what was your solution. Any help is greatly appreciated.
