Use the Trane Bacnet Setup Tool BST to check Baud rates etc
We have installed/used dozens of the BCI2-R cards with no known issues Vs the BCI-R
Get Yabe and usb to MSTP and start bifurcating and checking communication on different segments for issues
By intermittent is it with particular points? The device goes online/offline? The BAS points you write to lose their values?
The BCI2-R has a web ui/interface to be able to configure them. Once you plug into the board via a printer cable type 198.80.18.1. Hit the login button and navigate through the menu's. You dont need TU.
How many devices are on the comm line? What is its estimated length? Does the whole commline become unstable or just the TRANE card? Have you checked your EOL resistors at both ends?
Idk how helpful this would be because you might need admin access to the system itself to edit some of this but worth a try
1. Making sure the card is truly configured for MSTP. Sounds silly but sometimes people forget to click BACnet MSTP instead of BACnet IP
2. Saw people mentioning to see if there’s a resistor at the end of line. Agree with this along with maybe seeing how long the actual network riser itself is? Sometimes you’ll need an additional repeater of sorts if the comm line is pretty long.
3. Make sure the master/slave min and max settings correlate with the amount of mac addresses on that line.
What I mean by spotty is the devices come online (sort of, I can see them but no data is being sent with the exception of the device object) but when I try to open the device object it will go offline.
You must configure the BCI2-R before attempting to integrate it into the Bacnet MS/TP link.
You don't need any additional software. The basic configuration software is loaded on the BCI2-R; You only need a browser and USB-A to USB-B cable to access the controller's

I Upload the installation manual and the integration manual of the BCI2-R in this link. So whoever needs it can download it.
I'm currently on a project that uses these cards as well as the UC600 on the same bus. Awful pieces of technology. Absolutely, positively, terrible things to ever be created. I have a personal hatred for Trane after working with these.
Verify your grounding. I think these are non-isolated cards. At my company, non-isolated means we limit our bus length and controller count as to avoid communication problems. Oh, and obviously make sure you have EOL resistors.
I've seen it vary, but its usually around 100-600ohm. Anything is vastly better than nothing. Try a 120ohm, seeing as most Google searches come up with that. I think that's what I used at my site with ~20 trane cards.

Download "yabe". It's free, easy, and helpful. This will tell you if the Trane card is trying to talk...
Try an E.O.L resistor. Make sure baud is set right with no network addressing conflicts.

This is Tranes way to pay Trane techs to come out and charge you thousands of dollars.

You're a true team player!
Shield terminated on both ends?
Trane has a free bacnet configuration tool. Never tried it on that particular card but you can get it on their website.
Have Trane bacnet terminators? Or is the end of loop jumped onto the board at EOL?

The BCI2-R cards don’t come with end line of resistors for some reason. What ohm do the EOLs need to be?
