<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Brief recap; I have had an operational OP II system
for over three years, (three consoles, one expansion) and it started to display
on the consoles, NO CONTROLLER DATA, and indeed they were not communicating
with the controller. I could have any ONE console, connected, and it
would work. All addresses were checked and re-checked. </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Bottom line it was the controller board. I have had
such a bullet proof system, with HAI that I guess I didn’t trust my own
trouble shooting skills. Clearly you want to eliminate the physical layer
stuff, but if it all else, it may be the controller. I suspect it was due
to lightning, however I do have the system well grounded per HAI instructions. U46
was the defective device, also received an EO9 update, but no description what
that is. It had the latest ROM when sent in for repair. </span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Board was out of warranty, so repair cost was $200.
Nice chap Charlie on the return desk. </span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>ps – If you ever need to send yours in, make sure you
have the latest download from the controller. They are returned dumber
than a rock! Do the download while you can!</span></font></p>
