Network Interface 
vNet Device Models:

POWER OVER ETHERNET 
The Vaisala vNet PoE Network Interface (vNet 
Device), provides easy network connectivity for 
your Loggers, eliminating the need for an AC 
power source if your network supports Power 
over Ethernet. 
SYSTEM REQUIREMENTS 
vNet Device Drivers must be installed on a PC 
with the following minimum configuration: 
• Windows XP, Windows Server 2003, 
Windows Vista, Windows Server 2008, or 
Windows 7 (32 or 64 bit versions) 
• CD-ROM drive 
STEP 1: ATTACH HARDWARE 
Before you start: 
• If your Logger has an internal temperature 
Channel, it must be connected to a vNet 
Device with a built-in fan mechanism. 
• If you are mounting a vNet Device on a wall 
to hold a built-in fan mechanism, ensure the 
vNet Device is in the upright position (the 
arrow on the vNet Device bed pointing up). 
To connect a Logger to a vNet Device: 
1. 
back of the Logger. 
2. 
towards the two tabs before pushing 
down into the vNet Device bed (you 
should hear a ‘click’). 
3. 
then connect the vNet Device to the 
power supply or Ethernet outlet. 
Figure 1  Connecting a Logger to a vNet Device 
connection, insert the 
power supply barrel-end 
connector into the vNet 
Device and turn ¼ to the 
right. 
If your network supports 
Power over Ethernet, you 
do not need to connect 
an external power 
supply.

Note: If your vNet Device has Firmware 
v1.4 or higher installed (serial no. 
1411xxxx), and you are running 
viewLinc 4.3 or higher, enabling the 
viewLinc Aware Service completes 
device driver installation, discovery 
and configuration automaticall y .  
Refer to the vNet User’s Guide and 
viewLinc User’s Guide for more 
information. 
STEP 2: INSTALL DRIVERS 
Before you start: 
• Obtain an IP address for each vNet device. 
If you use reserved IP addresses, the 
DHCP server must be updated before you 
proceed with the installation. 
• Modify Firewall settings to allow the 
dgrunwiz.exe and dgcfgwiz.exe programs 
to receive incoming network connections, 
and unblock UDP port 2362 and multi-cast 
address 224.0.5.128.

STEP 3: DISCOVER DEVICE 
The Device Discovery function ensures that all 
vNet Devices connected to your network are 
identified by viewLinc or vLog software. 
Note: If you use viewLinc 4.3, this step may 
not be required. Refer to the vNet 
User’s Guide for more information.

STEP 4: CONFIGURE DEVICE 
The vNet device has a web-based vNet 
Configuration and Management interface 
which allows you to make configuration 
changes, restore default settings, and more. It 
is recommended that you log in to this interface 
to change the default password. 
Note: If you use viewLinc 4.3, this step may 
not be required. Refer to the vNet 
User’s Guide for more information. 
To log in to the vNet configuration interface: 
1. From a PC on the same subnet as the vNet 
Device, open the Internet browser and enter 
the vNet Device IP address or NetBIOS 
name, (for example, 
‘
x’ is the serial number). 
2. Log in using the default username root and 
password, 
dbps. 
veriteqxxxxxxxx, where 
3. Use the navigation pane to open the
