found this at sears the other day

Joe:
Could you please explain this pic? I see a data line and some type of white data block?

sorry,
brown 2 wire extension cord, then to the gray adapter, and out of pic is where its zip tied to the pole, then goes into the drop ceiling...
light glare makes the end of the cord look white, not brown

Ah...the old zip cord extension cord thru the drop ceiling trick & if anyone asks..."it's only temporary, sir, for the holiday rush"!!! LOL

oh, and that's a price checking machine

Just got reminded that I haven't posted this one yet, from the same Sears too
