Found these on Ebay.  Seemed reasonable and work fine with the WRT54G.  Same size power connectors as the V2 and up.  V1 didn't fit but that is 5VDC and personally won't be getting any more of those.  Here is the URL.

Sorry about that. This should work better. I did try it and it went there. The other got truncated somewhere along the line. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=121100493777&ssPageName=ADME:L:OC:US:3160 Kirk - N6SXR

Be aware this is NOT "Power over Ethernet" or PoE.   There is a standard for Power over Ethernet that involves voltage choices, switching, safety features, etc. when a device connects and tries to turn on. 

Plugging anything but the pigtail adapter on the "unpowered" end of a cable with the pigtail adapter might cause damage to the device.  It also won't power a standard Power over Ethernet device.

I believe these adapters are simply connectors and wires used to run a DC current down the unused wires on a 100 Base TX Cat5 cable.   When you use this on one end of an ethernet cable, the cable is no longer standard Ethernet nor PoE ethernet.  


Gigabit ethernet  uses all the wires in a Cat5 Ethernet cable.   If someone plugs a device with Gigabit Ethernet, such as a laptop, into your "pseudo PoE" Ethernet cable without the pigtail adapter on the other end, it might damage the laptop. Or switch, router, etc."

Standard PoE is also 48 V.  

You're probably OK as long as you have the pigtail adapter on both ends of the Ethernet and nobody ever accidentally or deliberately removes the pigtail on the "downstream" end and plugs directly into the Ethernet cable.  Just be aware that if you use these adapters, you have what looks like a standard Ethernet plug on the other end of the cable, but it isn't.

I'm not part of the development team, so take what I say with a grain of salt. I'm also easily confused.

That is MY intent for these, to use them ONLY for this project where the router is up a pole and there is one of these at each end.  Hopefully i didn't mislead anyone as I am new to POE.

And we are experimenters so it is assumed that we look at these things before we jump in.
