<div class="PlainText">Yeah, I had used the .ACD from there.<br>
<br>
Looks like it's trying to communicate with 3 watlows, only one of them is online (responds to pings) now.<br>
<br>
.26.190 = 1 = online<br>
.26.189 = 2 = offline<br>
.26.215 = 3 = offline<br>
<br>
Currently the US is set to use 1 and the DS is set to use 2.<br>
<br>
<br>
P.S. The COMCAL watlow is also offline.<br>
