Laroy,
Card output power is NOT the issue! True, our first run of boards
required calculations on the power supply, but ONLY if you were using
PoE. The extra voltage with the power supply you have tends to cause
extra heat and lockups. HOWEVER- this issue does NOT affect all boards
(that is why it is frustrating).
Demarc's box is metal, which is GOOD! Plastic does not act like a heat
sink, and that is a problem.
We are not shipping the RSUs yet, but stil on schedule. It will happen
in the next few weeks.

Subject: RE: UPDATE: [Karlnet] KN200 Problems
Kevin,
I have a chart that you sent me showing the voltage-vs-length for PoE.
It shows that for about 185 - 200 ft the voltage should be 16 to 17
volts for the kn200. Does the card output matter in this calculation?
(30mw, 100mw, 200mw)
I think your documentation on the website shows any voltage up to 48V
will work. You might want to update the docs if this is not the case.
The units I bought came with a 24V PS. What problems will the extra
voltage cause? Just overheating and lockup or can it cause damage to
the board or radios?
Here is a link to the units I bought, I'm sure your familiar with these.
Does Karlnet feel that these are ok as sold in the aluminum enclosures?

One other question: Is Karlnet shipping the RSU-KN50 units yet?
Thanks for your help and input.
