Use of the DS2406 switch for input
-
Can the DS2406 switch be used as an input to Mango? I see I can set the output binary value. My DS2406 is found by Mango but when I close contacts in the field, the state does not change in Mango. Dallas One Wire Viewer does see the field contact closure. For example, I want to sense air flow paddle switches and current switches such as CR Magnetics CR9321.
If not, can anyone suggest another way to do this with another kind of 1-wire input device?
Thanks for your help in advance,
Mike

any ideas on how you can sense in a 1-wire circuit ?
Many thanks

The DS2406 should already be supported via the SwitchContainer. If you are finding otherwise you can ship us a sample and test it out.

Hi
the DS2046 does work as a switch but not as a sensor (which its also capabale)
Rather than me send you one - can I ask if you can go to
https://shop.maxim-ic.com/storefront/searchsample.do?menuitem=Sample&event=SampleSearchLoad
where you can order free samples of all of the 1-wire componets

What specific part number are you using? They don't seem to have much in the way of samples at the moment.
-
My bad, I was looking for a DS2046. There is a MAX2046ETJ+ available. Is this similar enough to what you are using?
-
its DS2406
-
Yes, but that's not with Maxim-IC calls it. Can you specify the exact part that you are having trouble with?
-
-
Ah. That's a "2406", not a "2046". They only provide samples for the DS2406+ and DS2406P+. Which are you using?
-
ahh - my apologies
never could typpppe propperly
DS2406+

Hi
any update on testing ?
-
Sadly, no. The samples that Maxim sent i cannot use. When you say it won't work as a sensor, why is that? It should be reading the device's value on each poll.
-
ok - let me have a play applying a voltage to the switch side and see what happens - I am away at the mo so this will take a few days to achieve
If any one else can have a go at this then please feel free to chip in

OK, I will finally get off my butt and send you one of these like I promised.
It works with One Wire Viewer just fine by connecting a switch across it's inputs. I can see the state change in One Wire Viewer.
I could really use this functionality from Mango as well.

Is there any import restrictions to Canada? Special markings?

Document it as a gift of 0 value. This will avoid the astonishing duties and taxes that would otherwise be applied.
-
Oh, but if your device doesn't have a RJ connector, don't bother. I'm not set up for integrating components on to boards or anything.
-
I've got leads soldered to the board now.
On the input side: DQ, Com, +5VDC
On the output side I/O A, com, I/O BThe DS 2406 is mounted on the board with some pullup resistors.
I can do RJ-45 on the input side if you needed it.
-
I got test 1-wire equipment from hobbyboards. If yours is compatible with that, it should be fine.

any news on this - did you manage to test
