All of the Zen34's I have and the ZSE43 I have are 700 series.
One thing I found out after I excluded and reincluded was that the wake up procedure for the Zen34 was not what i expected. It was clarified here Devices Not Working with ZWJS [2.4.1.151 / C-8 Pro / ZW 7.22.2] - #17 by bcopeland and i am not sure if that would have fixed my issues actually.
