Configuration, Webswitch 1216H / Re: Connect points 35 & 36? Coax power jack size?

I should have clarified that i meant the polarity of the DC connector. It is not shown on the device to my knowledge.
It might have been implied that it does not matter which side is plus or minus, but i did not feel confident enough to try it.
I like to be on the safe side when it comes to electronics.

Thank you for your time.

Okej good to hear that i was wrong

Though luck 

I guess the error message is coupled to the way the 1-Wire protocol works. Like Jan said, every 1-wire device has a unique id used as a identifier during communications. When the bus master (webswitch) searches for a new (that has a unknown ID) slave device, is limited to only registering one device at a time by its search algorithm.
But this is all speculation on my part.

How does your network topology (structure) look?
There are some that are not suitable for use with 1-wire, due to signal reflections and signal cancellations, like:
     (S)  (S)
       \   /
(M)---¤---(S)  Or  (M)------(S)------¤--------¤------(S)
       /   \                                       |           |
    (S)   (S)                       [long cable]     [long cable]
                                                    |           |
                                                  (S)        (S)
Optimally the slaves should be linked in a linear fashion, like: (M)---(S)---(S)---(S)---(S).

You can use both AC and DC and the polarity doesn't matter.

I feel this is not stated in a clear way in the Webswitch specification. I had to find this post in order to get a straight answer.

Hi

I had the same problem just the other day.
I used only one sensor.
The cause was a mistake on my part were i had attached the sensor cables to the wrong port. The solution was to just switch the cable placement.

I think you have to scan and save a device at a time. You could probably not scan and save multiple (previously never attached and scanned) sensors to the webswitch.
Try attatching them one at a time, scan then submit them. After that you attach the chain of sensors and check if you get any temperature data.

I hope this helps you.
