I stumbled on the CAI WebControl I/O board on another forum. it is an exceptional value at $34.00. 8 TTL out, 8 digital in, 3 analog in, 1-wire temperature (non-parasite power and very voltage sensitive), and humidity sensor input, microprocessor with PLC or Boolean 4000 line of code possible. Order on Amazon.com

Hooks up to your LAN via standard TCP/IP. I can access it internally on any computer on the LAN or remotely off site with appropriate router settings.

I have it interfaced with Mango retrieving data with HTTP Retreiver data source. Took me awhile of googling to find the xml. It is not documented for some reason in the manual.

Latest firmware also reportedly handles X-10 output by using two of the DO and an RF transmitter (310 mhz in US). I am very excited about this since Mango never did implement X-10. I have not tried this yet.

Here is a screen shot of data source retreiving temperature sensor 1 data:

Love this part:

In a moment of rare SCADA-software sanity, the offset is zero-based.

This hasn't died, no, but nor has it come up much. I would suggest implementing as a module for M2M2.

Solved.

Instead of using port 25 for smtp at Cox, I used port 587 which is supposedly for mobile devices. Also, and probably the biggest issue was, I originally did not have a "from " address in the Mango system setup. So cox thought I was an annonymous spammer.

My cell phone (dumb phone) only receives the subject line since Cox is receiving the email in HTML instead of plain text. Al least I know something is going on with MAngo and can go check online.

As in another poster recently asked, it would be nice to have a selection for plain text e-mail or HTML in the system setup.

Thanks. Re Javascript, just ask Google. There's a ton of resources around.

I wanted to try to use the DS2450 A/D converter to interface with Mango to monitor field signals from HVAC equipment. I have only several temp sensors on my one wire so far. I use the standard serial adapter to my Win XP PC as the bus host.

I built a circuit to interface with and isolate from the field voltage which uses an LTV-814 (one channel) up to LTV-844 (four channel) AC/DC input opto-isolator. The output transistor of the LTV chip drives the input of the DS2450. I am using 5VDC (currently USB powered) to drive the output side of the LTV chip.

Initially it did not work. However after plowing through the DS2450 datasheet, I learned the default setting for the DS2450 for input voltage is 2.55 volts maximum on the inputs. Since I was using 5V it did not know what to do and returned a big fat 0.0 to Mango (and One Wire Viewer). I then used a voltage divider network to bring the input down to a level that the chip would recognize and report in it's default state.

An optional input value is 5.10V, but there is currently no way in Mango to select the input voltage or the resolution (default 8 bits) of the DS2450.

The default settings for memory map page 1, Control/Status starting at 08h is:
(hex) 08 8C 08 8C 08 8C 08 8C

If it could be modified to:
(hex) 08 8D 08 8D 08 8D 08 8D this would give 5.10V input enabled

The settings are all volatile and revert to default when the chip is repowered so they need to come from the host software every time the one wire bus is powered or reset. I'm not a programmer so I leave that to Matthew as a possible improvement !

Hope this helps someone.....at least I got to relearn hex to figure this out. Short lesson is if you are over the input voltage you will get 0.0 output. Also, when you really are at zero input voltage the chip output floats at 0.03 or so on all channels. I have two DS2450 and they both do the same thing.

Next job is to get it off my desk and into the field.

I finally got around to loading the newest version of Mango (1.8.2 I think). I enabled the option to discard what I consider bad data for the DS18B20 and this works just fine for me. No more flaky charts when i restart my 1-wire network! Thanks a bunch! For my latest version of my public page see:

Hi,
I just purchased the TED 5000 series... Will let you know how it works with mango shortly.

No news.
