Issue
Communication Port does not come online in Vista Classic. The port is correctly configured in Vista and Device Manager reports it as working correctly.
Environment
Vista
Loytec NIC-USB
Loytec NIC-709
Echelon PCLTA
Echelon U10
Echelon U20
Lonworks network
Cause
The communication port must be connected to a Lonworks network before either object will appear online in Vista. When the communication port is first created it will appear offline even if it is correctly configured.
Resolution
1. Create a communication port object in Vista Classic and configure it according to the manufacturers recommendations. It will appear offline in Vista at this point.
2. In Vista 4.5 and above, right-click on the communication port and select New>Device>Lonworks Network.
3. In the Wizard which pops up, tick the box 'Use existing port/server.
4. Ensure that the correct port is selected in the drop-down list.
5. Click 'Finish'
6. In Vista press F5 to refresh the display. Both communication port and network are now online (green)
