Hardware Overview and Installation
Network Connection
To connect the NI 17xx Smart Camera to the development computer through a network,
complete the following steps.
1.
Verify that the development computer is connected to the network and powered on.
2.
Using an Ethernet cable, connect from an Ethernet hub or other network port to Ethernet
port 1 on the smart camera.
The NI 17xx Smart Camera is now connected through a network and is available for additional
configuration with the development computer.
Subnet Considerations
To use the NI 17xx Smart Camera on a subnet other than the one on which the development
computer resides, first connect and configure the NI 17xx Smart Camera on the same subnet as
the development computer. Next, physically move the NI 17xx Smart Camera. Contact your
network administrator for assistance in determining which network ports reside on the same
subnet.
IP Address Assignment
If the NI 17xx Smart Camera is connected directly to the development computer, the device will
use a link-local IP address. If the NI 17xx 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 17xx Smart Camera to use a static IP address. If you cannot locate the NI 17xx Smart Camera
on the network, first refer to the
Firewall Configuration
section, then assign a static IP address
or contact your network administrator.
Note
If the NI 17xx Smart Camera has a link-local IP address (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 17xx Smart Camera.
•
The DHCP server does not allow other devices to use the IP address that is already assigned
to your NI 17xx Smart Camera.
