Dear Artisan user group;
I have received an error I have not seen before using a Mac with the latest solfware : Sierra with a 64 bit system.
We have installed the CP210 driver with our data logger using Omron controls.
Here is a screen shot:
Modbus Error: Read float() hex() argument can't be converted to hex@line 30521
Could it be we have the wrong driver installed?
We use to use the FT232 driver but data driver was upgraded to a new model that has worked with the CP210 driver on most models (this data logger is setup for future use with Bluetooth capabilities)
I'm relatively new to artisan. Been using RoastLogger for years but now that
I have my phidget 1048 I don't need the camera/ocr feature anymore.
I haven't been able to locate the help file or information about the
settings under Config-Device - Phidgets tab. For instance, Async check
boxes, raw data, change etc. I've found everything on the github page, but
maybe I just haven't been successful in pinpointing the proper area to look.
Secondly- I'm roasting on a Diedrich IR-24, which has a thicker J
thermocouple than the one I've hooked up to artisan, which is a K type 1/8in
I purchased here:
The temperatures are around 30 degrees F higher on the thinner K
thermocouple than what the roaster is reporting, even though my
thermocouples in the roaster are mounted next to each other (didn't want to
piggyback on BT of the roaster to phidgets)
Does anyone have any experience in this area? Perhaps the simple fact that
the probe is thinner means the readings will be different, but I do not
know. It would appear that the readings on the roaster are accurate while
the other is much hotter.
Just getting started, and appreciate any guidance.
I received many complaints on noisy RoR signals over the year. The ongoing work of Scott Rao and a broken TC made me reconsider my own roast logging setup. As I had collected many different meters and probes over the years, mostly for development purpose, I wonder which one I should best install in my machine.
My goal was to minimize both, the signal to noise ratio as well as the introduced signal delay, especially for the RoR. Thus I came up with a setup that would allow me to compare different setups on the amount of idle noise they produce.
Details are here: https://artisan-roasterscope.blogspot.com/2019/03/on-idle-noise.html
I switched from TCs to RTDs for reasons detailed in the post and I am quite happy with my new setup,
My roaster is apart for mods and it is getting to the point that I
could take advantage of a second another VINT hub. I just want to
check if that is possible, please.
Also, I noticed that there is no mention of Phidget 1136 (diff. air
pressure) on the supported devices page. Has support been dropped?

here the Phidget ‘ambient’ devices seem not to be communicating…
I just spotted this late tonight. Tomorrow I’m off for 2 days.
It’s no a problem here but maybe it’s not just my system where this stopped.
