Re: FC-SCG FACET-Card - RS485

Thanks a lot for the prompt responses! Yes, RS485 is a little hard, since there is no industry standard. I realize that my personal experience should not be taken as the only viewpoint, but maybe you can add my viewpoint to yours and make something cool out of it. Most all of my RS485 exposure is fo...

Re: FC-SCG FACET-Card - RS485

Wowee, of all the interfaces I have had to mix, I have not had to mix RJ45 and RS485. I would need to find an adapter that makes the RJ45 pinout turn into what I need. Not to be a big downer, but that might be one of the oddest combinations I have ever seen. You may have better sales with a differen...

Re: Fitlet processor

Extract from that link: The BeagleBone Black might be useful for specialized embedded use-cases or penny-pinching Linux hobbyists, but for any real ARM Linux development use or desktop experiments, it's far too slow. I can't find any use-case myself for the BeagleBone Black as it's far too slow for ...

Re: FC-SCG FACET-Card - RS485

I looked at that link and found very little of use. The card is pictured beautifully, but it is only when you get the documentation open that you find the pretty picture is missing the main piece - the part that seems to actually talk UART - and the diagram you do get is really hard to see - it look...

Re: Fitlet processor

That is a good comparison of 2 chips you all offer - but there is nothing on the other devices chip: TI AM3352: 1000MHz ARM® Cortex™-A8 I had a VERY hard time finding info on it - I figured you all had heard of it or declined using it or had something on it. Alll I can find quickly is that it is not...

Re: Fitlet2 pictures of options - top-covers

I saw that page - of all the files there, only the deep bottom cover includes something that does not require a special reader, and it is a handy 3D drafted drawing - that does not really show either how it compares to the normal bottom or how it affects the overall dimensions of the device. I do no...

Fitlet processor

I am looking at a Fitlet as a possible replacement/substitution for an Automation product I currently use a lot - but that is a little flimsy in it's construction and has only a 1yr warranty. Most of the specifications are pretty straightforward, but I am having trouble finding comparative data on t...

Fitlet2 pictures of options - top-covers

I was rummaging around and found - through the process of building my own on the website - that there are different tops that can get put on the fitlet2. Standard top-cover Industrial top-cover [HTI] Low-profile top-cover [HTL] Single-board-computer (no housing) [HBPN] Do you all have pictures/dimen...

FC-SCG FACET-Card - RS485

I see that there is a FACET Card that lists RS485 capabilities. I do Building Automation, and I am looking to see if it will allow for BacNet over RS485. https://fit-iot.com/web/product/facet-canbus-rs232-rs485-gpios-fitlet2-parts-fscg/ I understand I would need to supply the software side of things...
