I know of the S4 gateway under beta right now.
I was also wondering what other options would be good? I have a site with NCM's and I need this exposed to Bacnet. Would a FX20 or a N30 be viable gateways? I'm not fully versed in JCI, I'm coming from another vendor. What has worked successfully for you with this type of setup? What's the most cost effective? Yeah, I have a lot of questions...:D Just looking at all options.

How much of the existing system do you want available via BACnet ? How many NCM's? How many N2 devices ? How much "Control" exists in the NCM's ?
Need to know "How long is the string" before we jump in with suggestions
An FX-60 would the prefered device over a 20 or 40 but that depends how much you need exposed as BACnet.
The S4 N2-BACnet "Router" may or may not be what you are looking for. As you said it's still beta right now.

Johnson Controls NIE. Basically an NAE but imaged to integrate NCMs. You can expose that to BACnet and integrate it BACnet/IP.

FX60s definitely. Then you aren't tethered to JCI anymore for upgrades/updates/service. Leaving the NCMs and integrating with an NIE is just a band-aid and not a permanent solution IMO. You still have to maintain the NCM, maintain a PMI OWS, and it's one more thing to fail.

I have successfully used the Fieldserver device to do this. I paid their reccommended integrator to do the datafile.
Thanks. Mike

Back to one of your original questions... "Fahgetabout the N30 all together" !
1. it's obsolete, 2. it's not worth the headache, 3. much better options exist. IMO !

After checking the docs on it, it looks like its a N30 on site. Hm. I could of sworn it was something else...anyway...looks like I need to double check what's actually on site.
Ok, if this is the case, the N30 already supports bacnet. If anyone has a link to the tech docs for the N30 and how to set up the bacnet side, it would be greatly appreciated :D

What are you goint to be looking at the "BACnet Stuff (N30)" with ?????
If you need tech info on the N30 at this point you are likely in for an uphill battle. :(
Good luck, man.:)

With all the time/headache you are going to put into this you probably could have paid for two FX-60's and done it right...with no backassward bacnet/n2 kluster.

Integrating an N30 Bacnet/IP is a PITA. The polling hammers the hell out of it as on the Bacnet side of things it thinks it is one device. The CPU idle times go through the roof and your updates are really slow. If you already have to put in a FX60 why not remove the N30 and tie the N2 bus directly to the FX?

What kind of site is it? You might have to think twice if there is alot of GPL running around on the site.

You can have all the JCBASIC, and GPL processes in the world. FX's are not NAE's. Converting it/better ways to do the same thing is fast and simple.
