Nodelink RS232?

Recommended Posts

I have just purchased the insanely expensive RS232 interface for my carrier infinity heating system. Do you have anything in the automation shack portfolio to use with it? Basically one uses RS232 to set commands and it get status of zones, temp?

 

If not I will take a look at autelis... Or maybe IP to RS232 interface.... Not sure...

Thanks for posting this question, I didn't know there was such a thing.  I've got a really similar situation.  My lighting system has an RS232 interface and I want to more tightly integrate it into the ISY.  Right now I can send commands to it as a network resource (IP->rs232 device is running on it) and it will do things but the ISY has no idea what the state of the lighting system is.

 

I've been waiting for polyglot to be more supported with more examples and I was going to make a run at trying to do my lighting system but I'm not sure my python is good enough to pull it off.

What IP ><> RS232 device do you use - i am flailing here and would like a recommendation :-) ?

 

What i think i need from the device / app / node that talks to it is:

  1. ability to send periodic request for status updates (i am not sure the RS232 of my thermostat puts status onto the wire unsolicited)
  2. ability to define incoming data as temperature and thermostat data so that it can be identified as such by ISY

See this post I made awhile back about my RS232 setup.  Towards the bottom it mentions SENA LS100 and Wiznet WIZ110SR as ones I found referred to by an app developer that made an app for my lighting system.

 

The device I am using I bought off of ebay and is discontinued is Startech NetRS232_1.  This has been replaced by http://www.startech.com/Networking-IO/Serial-over-IP/1-port-RS232-serial-over-ip-adapter~NETRS2321P which is a bit expensive for what it is.  I think the Wiznet is the cheapest of this bunch.  They do make multi-port units too.

Thanks, did you find an enclosure for the WIZ110SR ?

 

I just bought this star tech  for $50 boxed like new http://www.amazon.com/gp/product/B000YB0NOS?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00

If you're running a Pi just add a $10 com module.

 

I've got some parts to try this.  I also was thinking about trying a rs232->usb on the pi because I need two rs232 ports.  Right now, using the rs232->ethernet I can set it up as a network resource from the ISY.

Cool, and is that better than using a USB COM port adapter?

 

It removes a point of failure that a usb->rs232 adapter may introduce -- I would guess less power consumption too.  Less complexity going straight to rs232 from the pi since it speaks rs232.  Note that the pi's rs232 interface does not support all signals on all the pins (rare that someone would need all of them).

 

In my setup, I need two ports and the pi only has 1 so I may need to go the usb route.  If you read reviews on usb->rs232 devices you'll note some people complain about certain models or experiences but others do well with them.

cool thanks!  i still like the idea and flexibility of having the RS232 port and RS485 modbus of my heating system exposed via IP then i can mess with a bunch of different things connecting to them.  I still orders a couple of the rs232 headers off ebay - that will come in useful.

Yeah, I'm kind of torn between the two approaches.  If the RS232 is faster for response time than rs232->ethernet then that could push me that direction.
