Are you using BACnet MSTP to integrate into the RTU's CCN devices?
I was not aware that Jace's could directly tie into the Carrier RTU CCN buss, which is a EIA485 buss, but the data packets are
CCN properitey not conforming completely to EIA485 rules.
I am not a Jace expert (yet), but I do have extensive skills on BACnet MSTP and IP integration, and CCN integration.
If the existing RTU's have CCN Controls, and no "Carrier CCN or Carrier i-VU BACnet" devices installed, you may need to get some
Carrier BACnet Translators boards, or a Carrier i-Vu UPC Open Protocol converter onto the RTU's and then use someone familiar with mapping CCN points to BACnet points, then you can interface via BACnet MSTP.
This can be a bit tricky, and I do integration every day. Carrier CCN points have refresh and write limitations like almost all legacy controls do, that can greatly limit some of the integration control requirements.
Let me know if you need more info.
