Hi Rainer,<br><br><div class="gmail_quote">2009/9/22 Rainer Fuegenstein <span dir="ltr"><<a href="mailto:rfu@kaneda.iguw.tuwien.ac.at">rfu@kaneda.iguw.tuwien.ac.at</a>></span><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

AQ> is that expected? remember that I've not followed the initial thread, nor<br>
AQ> had time to do so...<br>
no. every time I connect the serial cable from the SCD to a serial<br>
port on a computer, the current drops by about 1A (meaning that<br>
suddenly there's a load of about 12W). this "virtual" load disappears<br>
as soon as the serial cable is disconnected.<br>
<br>
In the meantime I figured out that this can't be a ground loop. even<br>
if there's just battery / SCD / PC (solar panel and ethernet cable<br>
disconnected), the current drops on connection of the serial cable.<br>
<br>
I want to run some more tests with different ports / cables just to be<br>
sure before I contact IVT again.<br></blockquote><div><br>ok, let us know the results... <br>btw, do you have an LCD display to double check the data?<br>also, have you seen and tried Arjen's advice on set_dtr() and set_rts() calls?<br>

AQ> happy to see the first NUT SCD working ;-)<br>
<br>
hopefully it won't stay the only one :-)<br></blockquote></div><br clear="all">for sure ;-)<br><br>cheers,<br>Arnaud<br>-- <br>Linux / Unix Expert R&D - Eaton - <a href="http://www.eaton.com/mgeops">http://www.eaton.com/mgeops</a><br>
