 		 #185130 - Not for clocks
Responding to: ???'s previous message

Is the cabled power necessary? If you say that there are options for power at each clock site then I'll make some other suggestions for you. Post back when you can.

Since I was asked to install the clocks also I thought power through the cable will be easiest. But I surely am thinking of other ways of doing it, like makeing each clock run at 220VAC and make the data link through r.f. especially when I had to drill through concrete last time to install the cables in some parts of the building.
I'm experimenting with NRF24L01 with power amplifier now and have the option to use WIFI module also.
Once I get the contract I can pick and choose since it will pay for this research.
Any other ideas are welcome dear Michael?
