Can someone tell me what is the best way to control the OA damper opening when I have the OA enthalpy, OA RH, OA Temp, Dew point, moisture content? Right now, at one of our customer sites, the...

Yes, I am working on a CCPIII system parallelly too. The good thing about that is I have been able to see and talk to the VAV controllers on that communication trunk. All I did was got the CCPIII out...

Thanks. So, the 1st logical way to test this out would be to go ahead and test out the devices under 1 single comfort manager. So, I will go ahead and take the +,- and SHLD wiring landed to that...

Thanks, Controldude. Anybody here have any thoughts on getting around with Isolated com3 communications with an Ax? I know there is no driver for isolated com3 yet, does that mean there is no way to...

So, you mean to say COM4 didn't work for the VariTrac comfort manager then? I am a little confused here. Please note that this is not a Summit system though

You are right, the driver is only good for non-isolated COM3. This control system isn't very old. I know Trane has COM4 since 1990 and I wish I was almost positive that this is a definite COM4. The...

Well, I have tried COM3. I still seem to be out of luck here.

Anyone here ever dealt with Trane tracker L systems? I am looking at a job that has 1 Trane tracker L, 5 Trane comfort manager panels that serves 5 variTrac and then there are also 2 Voyager at the...

Can someone who has had success integrating Trane tracer L comfort manager into a Niagara Jace? I am working on a project that has 5 of these Trane comfort managers all interconnected to the central...

Hello,
I am integrating a Trane CCPIII system with a Jace2. Well, so far this Jace has both COM3 and COM4 installed on it on demo mode. with COM4 disabled, when I discover devices on COM3, I see...

I am taking over an existing MN-HPFC line of controllers in a functional NW8000 BAS system. No matter whether I put this controller in Local or Ems control, the damper would not move.Also, any...

Based on these forum postings am I understanding correctly that any Tracer L system is a com3? I believe there are drivers out there in the market that sell Trane com3 drivers. I just wanted to make...

Thank you so much. Would you happen to know regarding EMTF model# also? I know that building has Varitrac Comfort Manager controls and actually 5 of those. Thanks and appreciate all of your...

Paulir, could you please tell me whether it is com4 for both CCPIII and EMTF and BMTK also? Thanks a bunch!

Has anybody had success with integrating Trane Tracer L systems with the Niagara AX Jace? I know there is com3, com4 and com5 out there for my AX drivers, but just wasn't sure if the model # I am...

Is there a way to find out the communication protocol like com3/com4/com5 given a Trabe part#? I am looking at a Tracer L system with part# EMTF000AAC0210014?

I have another Trane system who's...

apprentice3, I know this is an old posting but I was curious as to what driver did you endup using to integrate with Jace. I am looking at a job that has a Tracer L system who's part# is...

Yes, I am indeed trying to connect this to MZII using regular 2-wire RS485 communication. My converter Hexin210B has T- and T+ inputs that I am connecting to MZII's ASD- and ASD+. I have tried all...

t-reck, did you connect it as a 2-wired or 4-wired? Basically I am asking if you directly connected THE asd+ and asd- to + and - on the converter's RS485 T+ and T-? Thanks!

t-reck, Would you mind sending a copy of your working PSI to me? my email is on my profile. Thanks a lot.

Thanks, ShoreControlGuy. Would you happen to know where do I find vserial feature under services in my station? I understand that this feature must be seen under the services folder under config in...

t-reck, thanks for your response. Could you tell me which version of PSI are you using? I am using 4.1 running on a Windows 7 PC 64-bit OS. For whatever reasons, I am not able to get my PSI to talk...

Hello all,
Are there any special settings in the PSI setup that has to be made before one can talk to MZII in the tunneling mode? I have my PSI baud rate set to 19200 and use a COM port of 15 which...

t-reck, Well would you mind telling me the exact part # of the USB to RS-485 converter? Also, at what baud rate were you able to communicate?

Have you tried using seria tunnel feature to talk to...

Has anybody out here had success with using Niagara serial tunneling to talk to MZIIs via PSI without being direct connected to the MZII controller? I am running Windows XP 32-bit with Niagara...
