Subnet Considerations
To use the NI 177x Smart Camera on a subnet other than the one on which
the development computer resides, first connect and configure the NI 177x
Smart Camera on the same subnet as the development computer. Next,
physically move the NI 177x Smart Camera. Contact your network
administrator for assistance in determining which network ports reside on
the same subnet.
IP Address Assignment
If the NI 177x Smart Camera is connected directly to the development
computer, the device will use a link-local IP address. If the NI 177x Smart
Camera is connected to a network that has a DHCP server, the device will
automatically obtain an IP address. You can also configure the NI 177x
Smart Camera to use a static IP address. If you cannot locate the NI 177x
Smart Camera on the network, first refer to the
section, then assign a static IP address or contact your network
administrator.
Note
If the NI 177x Smart Camera IP address is 169.254.x.x, the device is only accessible
from the local subnet. To access the smart camera from a remote subnet, configure the
smart camera to obtain an IP address from a DHCP server or manually assign a static
IP address.
DHCP IP Addresses
Using a DHCP server to assign an IP address has the following advantages:
•
The DHCP server manages the IP addresses of the network. You do not
need to know the IP address of the NI 177x Smart Camera.
•
The DHCP server does not allow other devices to use the IP address
that is already assigned to your NI 177x Smart Camera.
Although using a DHCP server simplifies IP address configuration, using a
static IP address can be more reliable. Consider the following potential
issues before using a DHCP server to assign an IP address to the NI 177x
Smart Camera:
•
If the network has both static IP addresses and IP addresses managed
by a DHCP server, the DHCP server must be configured to not use
reserved static IP addresses. If the DHCP server is not configured this
way, the DHCP server can assign a reserved IP address to another
device, causing address conflicts on the network, which results in some
devices being unreachable.
