Reaper, check out the table on page 2

You'll also need this expensive do-dad to serially connect to MN 2000 sensor to the MNet-CI software set up the MN-FLO VAV controllers. I agree the software is straight-forward, but the special interface/cable is a must to be able to use the software.
MN-CIM. TAC MicroNet (2000 non LON) Controller Interface Module for use with the TAC MicroNet Controller Interface software or the balancing software.

If you don't need to do very much adjustment, you can possibly do without the direct connect to the MN FLO vav controllers IF you have access to the Barber Coleman front end. Also, IF Network 8k points have been created that integrate these VAVs into the Network8000 interface, you can overide some settings in the VAV controllers from the NW8K interface. Settings like VAV min/max flow rates; heat flow setpoint, heat/cool set points etc from those integrated points/blocks.

However, once you need to replace a controller, I would think you'd have to get the interface module/cable to get the replacement VAV controller flow rate measurement calibrated. Especially if the tstat sensors have a display on them and your controller configuration doesn't use defaults.

I do have the MN-CIM cable. I can't seem to communicate with any controllers. I am running Windows 2000 PRO. Is this program compatible with my laptop or do I have to boot into a true DOS? I keep getting error # 510. Thanks for any help.
 
Not sure what error 510 is at the moment. I don't recall any trouble running this software coming from the operating systems -dos; win95, 98, 2000, or XP pro. -only trouble has been on laptops when starting in the late 90s laptops stopped providing enough power to properly run the MN-CIM cable interface. There's a Black Box or B & B Electronics product recommended by Invensys I got that fits between the 9pin serial port on the laptop and the MN-CIM. The product has a wall wort power supply and supplements power to the MN-CIM beyond what the laptop provides.

I have a sheet or pdf somewhere on this product, & I'll forward when I find it. I haven't used a laptop to talk with these vavs for 12-15 years. We instead just extended the serial cable on the MN-CIM up to the nearest tstat and leave it plugged into the tstat, and a serial port on a desktop PC on the other end, and talk to any VAV in the system by addressing the integrator number, : , then the VAV number. Then if physically working on or changing out a controller, we may have a person at the PC and one at the VAV connected by radio or cell phone, or just run/walk back and forth. Wasteful I know, but we don't do that much of it.

Not sure if just pulling the MN-CIM plug on our desktop serial port will result in error 510 or not when trying to connect to a VAV, but I'll try that and note the error. I have a 4 yr old laptop and don't recall connecting with the MN-CIM with that laptop. The only trouble I've had connecting however is from a laptop... and possibly some PC serial port config errors on a desktop.
 
Reaper, I didn't try it out myself, but I found the pdf and it says the insufficient laptop serial power results in error # 510. Hope the attachment attaches.. it explains the problem and the fix.
