You may be experiencing firewall issues. If you are having difficulty detecting the system
and setting up the IC-317x on your network, you must configure the firewall to open the
TCP/UDP ports used by the IC-317x 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-317x
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.

inputs on the IC-317x isolated
power connector and that the contact at the screw terminals is solid. Because these outputs are
electrically isolated from the IC-317x device main supply, they require power in addition to
the IC-317x main supply.
LED Error Indications
The IC-317x indicates specific error conditions by flashing the STATUS LED a specific
number of times.
