Symptoms
Upon running the IP Manager on a Windows Vista PC the following message is displayed but
your network card is never assigned an IP address.
Cause
If Windows Vista does not see an IP v.4 address (as is the case when a DHCP device such as the
DI-720, DI-730, or DI-785 Ethernet products) it automatically defaults to IP v.6 (as opposed to
the widely used IP v.4). As a result the network card never gets an IP v.4 address and neither does
your device.
This is a Windows Vista issue that will hopefully be resolved in a future Windows update.

DI-720/722/730/785 Ethernet Installation on a Windows Vista PC
Resolution
To resolve this issue:
Connect your Ethernet instrument to a DHCP network/router or directly to a Windows XP
PC (no router required) to assign it a Static IP
The DHCP network/router (or Windows XP PC) will assign the DI-720, DI-730, or DI-785 a
valid IP address. This will allow you to run the IP manager and manually assign the unit a generic
static IP (an IP address assigned by the DHCP network/router (or Windows XP PC) will be lost
when the unit is powered down while a manually assigned static IP address will be retained).
Figure 1
Connect your DI-720/730/785 via a DHCP network/router
in order to assign the unit a static IP address.
Figure 2
Windows XP uses IP v.4 exclusively allowing you to run the IP
Manager and assign your Ethernet instrument a static IP address.
Once your instrument has been assigned a static IP address it can be connected directly to a
Windows Vista PC. The Vista PC will now recognize the IP v.4 address and maintain the default
IP v.4 network configuration. As a result the network card will acquire an IP address and the IP
Manager will run as intended.
Note: It may be necessary to change the static IP address of the device to match the subnet of the
network card. For instructions see the “Change IP Addresses” section of the DATAQ Instruments
TCP/IP Manager help file.
Applies To
DI-720, DI-722, DI-730, and DI-785 Ethernet (ENA and ENB) instruments running on a
Windows Vista PC.
