assigns the same IP address to another device. Either remove or reconfigure the other
device, or reconfigure the IC-3173 to use a different IP address by putting it into the IP
RESET state and restarting into the normal state. Refer to the
IC-3173 User Manual
on
for instructions on how to perform an IP RESET.
•
The cable you are using may be inappropriate for the speed of your network, causing
network communication dropout. While 1,000 Mbps communication over short cable
lengths can be achieved with the CAT5 cable commonly used for 10 and 100 Mbps,
CAT5e and CAT6 cables are more reliable and recommended for 1,000 Mbps links. The
IC-3173 has the ability to perform auto-crossover, allowing the use of straight or
crossover Ethernet cables, independent of the connection configuration.
•
The IC-3173 is configured to acquire an IP address from a DHCP server, but no DHCP
server is available. By default, the target will automatically attempt to connect to the
network using DHCP. If the target is unable to initiate a DHCP connection, the target
connects to the network with a link-local IP address (169.254.x.x).
•
You may be experiencing firewall issues. If you are having difficulty detecting the system
and setting up the IC-3173 on your network, you must configure the firewall to open the
TCP/UDP ports used by the IC-3173 and the host machine. Refer to the following table
for more information about TCP/UDP ports.
Table 1.
TCP/UDP Ports Used by the IC-3173
Port
Type
Details
3580 TCP/UDP Reserved as nati-svrloc (NATI-ServiceLocator). Used by MAX to locate
remote targets.
7749
TCP
Used for remote image display (not reserved).
7750
TCP
Used for NI-IMAQdx remote configuration (not reserved).
3363 TCP/UDP Reserved as nati-vi-server (NATI VI Server). Used by Vision Builder AI
to configure a remote target.
If your firewall is controlled remotely or you are unsure about configuring the firewall, contact
your network administrator.
No Software is Installed
MAX reports that no software is installed. Install application and driver software on the
IC-3173.

Cannot Drive Isolated Outputs
Verify that you have power connected to the V
ISO
and C
ISO
inputs on the IC-3173 isolated
power connector and that the contact at the screw terminals is solid. Because these outputs are
electrically isolated from the IC-3173 device main supply, they require power in addition to
the IC-3173 main supply.
