coupler. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

manual (very simple), one end to one phase where I have some UPB devices and
the other to the other phase with some other UPB devices. The red led in the
coupler is on, but I can’t communicate with the devices in the other
phase. Has anyone been able to successfully use the phase couplers? Any tips on
what could be wrong. The couplers I’m using are Revision A1. <o:p></o:p></span></font></p>
