Why can't I log in to viewLinc using the correct username and password?
Ensure the viewLinc Enterprise Server service is running: If viewLinc is not running, a blue screen and status message appears on your desktop display. If the viewLinc Web service is not running, you will see a browser error message.

I have entered incorrect login credentials too many times and the account is now locked. How can I unlock the account?
Contact an administrator: administrator users can both unlock and lock user accounts in the Users and Groups window. For more information on administrator options related to account locking, see Locking and unlocking user accounts.
Why can't I see any Zones and Locations?
viewLinc Zones and Locations are only visible if a group has been granted permission to view them. viewLinc Administrators set up group permissions on Zones. Permission to a Zone is required before you can access Zones and Locations in Sites Manager, Sites, Alarms or Events windows.
Why can't I access all viewLinc navigation pane windows?
viewLinc Administrators set up group rights to functional areas of viewLinc. If you require additional rights to access another viewLinc window, contact your Administrator.
Why am I receiving a device configuration alarm indicating a low battery alarm when I know the batteries are new?
If you are using an older model DL data logger, some low battery alarms are triggered even when the battery is not the issue. Look up the event corresponding to the device configuration alarm in the Events window, and review the event details. For more assistance, contact Vaisala Technical Support.
I'm receiving communication alarms in viewLinc. I think my network device or Vaisala device has stopped responding. What do I do?
- Make sure your data loggers and transmitters are plugged in and/or batteries are full.
- Make sure your network devices are connected to a power supply and the power supply is plugged in. On a Digi or vNet network device, the power light on the front of the device should be solid red.
- Ensure each device is connected to and communicating with the network. Try to connect with the device (see Testing network communications).
- If there is communication between the device and the network, check that the Vaisala-supplied cable is connected properly. If the light is solid red, there is a problem with the network device or device cable. Make sure your device has been configured to use RealPort (see http://www.vaisala.com/en/lifescience). If this still doesn't fix the problem, go to step 6.
- If the light is working correctly but you are still receiving communication alarms,
open Windows Device Manager on the viewLinc computer and ensure the device is still
installed:
- From the Windows Control Panel select .
- Under the Multiport serial adapter category in Device Manager, look for duplicate drivers using the same COM port.
- If the light on the cable is not working properly, open vLog and determine if the cable can communicate with the Vaisala device. If there is a problem with the device communicating with the vLog graphing application, it is likely the device or device cable is not functioning properly. Try connecting the device to a new vNet or Digi networking device, or to a computer using USB, and see if you can connect to it from vLog.

Vaisala OPC UA Server Service not running
Check your Group Security Policy settings to make sure your user account has the necessary permission to run software on the installation server.
By default, both viewLinc Enterprise Server and Vaisala OPC UA Server software are installed as Windows services. These services are only permitted to run on the LOCAL SYSTEM user account, the Windows default account which has full control on the system. If your computer system is configured with custom security settings, the viewLinc/Vaisala OPC UA services may need additional configuration to run.
- Go to the Windows Start menu and open or type Services.
- Locate the Vaisala OPC UA Server Service and open the Properties window.
- On the Log on tab select This account, then enter an authorized username and password. The user must have read and execute permission on all installed program files sub folders, inheritable Full Control access on all sub folders, and network access rights to allow it to connect to other systems.
