    Commission the JCI integrater (MIG) with VT-100 thru the commission port and run the port analizer on whcih ever port you are using. This will show if you are getting data or not.
    I believe the default port data is 9600, 8 1, and none for the comm port.
    Hope this helps...

    Similar on Trane side. Connect to mini-monitor port and watch bacnet sends and receives. Also check rs232 cable.
