Troubleshooting and Common Questions
ENET-232 and ENET-485 Series User Manual
I powered off my serial device server before recording the flashing
PWD/RDY LED pattern. What should I do?
Try to duplicate the error before calling National Instruments for
assistance. Recording the PWR/RDY LED pattern is not critical to the
operation of your serial device server, but it saves you time and helps
National Instruments to diagnose the problem quickly and accurately.
Why does NI Ethernet device configuration list my box as
when I know my network uses DHCP?
For up to one minute, the serial device server attempts to retrieve network
parameters from a DHCP server. During this time,
utility display. If this status does not change, there are several reasons why
DHCP may fail to respond. One of the most likely reasons is that your
subnet has no more available addresses to assign using DHCP. Please
consult your network administrator to determine the specific reason for the
problem.
I just added a serial device server to the network, but it does not show
up in NI Ethernet device configuration. What is the problem?
Allow at least 15 seconds for the serial device server to complete its
power-on self tests before launching device configuration or clicking
Refresh.
Communication between NI Ethernet device configuration and the serial
device server is not guaranteed. Though unlikely, it is possible that the
communication gets lost in the network. Click Refresh more than once
before concluding the device is not discovered.
Verify that the serial device server shares the same subnet as the computer
running NI Ethernet device configuration. NI Ethernet device configuration
cannot communicate with devices through gateways on the network and
will not discover devices on another subnet.
