These parameters are listed below.
Chapter 3 Ethernet Configuration For a Network without a Network Administrator If you are assembling your own small Ethernet network, you can choose your own IP addresses. The format of the IP addresses is determined by the subnet mask. You should use the same subnet mask as the computer you are using with your GPIB-ENET/100. If your subnet mask is 255.255.255.0, the first three numbers in every IP address on the network must be the same. If your subnet mask is 255.255.0.
Chapter 3 Ethernet Configuration Verifying the Hostname The NI Ethernet Device Configuration utility automatically verifies that the hostname for each DHCP-enabled device matches the DNS entry for the assigned IP address. This verification process automatically occurs when you either run the utility or click Refresh. The utility alerts you as shown in Figure 3-4 if it detects a problem with the network settings. Figure 3-4.
Chapter 3 Ethernet Configuration 4. Review the network parameter settings in the Properties display. 5. Confirm that the device is in network configuration mode and click OK. The device reboots with the new settings in effect. 6. After the device reboots, click Refresh to verify that the hostname is now valid.

As the update utility transfers the firmware image to your GPIB-ENET/100, the Update Progress status bar fills, and the Current status box describes each step in the process. The Current status box reports whether the firmware update completed successfully or failed. The GPIB-ENET/100 automatically reboots with the new firmware in effect. 6.
PWR/RDY LED Signaling A This appendix describes how to interpret the PWR/RDY LED error codes. PWR/RDY LED Overview The PWR/RDY LED has several purposes on the GPIB-ENET/100. When you first power on the unit, the PWR/RDY LED alternates rapidly between red and yellow while it completes its power-on self-tests and acquires network parameters.
Appendix A PWR/RDY LED Signaling Step 1. Count the Long Flashes A three-second interval, during which the PWR/RDY LED is yellow, separates each repetition of the sequence. The sequence begins with a series of long one-second flashes—that is, one second red, one second yellow. These long flashes represent the digit in the tens column. There can be one to nine long flashes, which represent digits 1 through 9.
B Troubleshooting and Common Questions This appendix describes how to troubleshoot problems and answers some common questions. Troubleshooting Hardware Problems Try one of the following solutions if you encounter hardware problems: • Verify that all cables are securely connected to the GPIB-ENET/100. • Verify that the unit is plugged in and powered on. • Verify with the network administrator that your IP address is valid and that the network is set up to recognize the IP address properly.
Appendix B Troubleshooting and Common Questions • The entry in the Bus/Device menu should correspond to the bus number displayed below the checked bus selection box. • The IP address or hostname of the GPIB-ENET/100 should be visible in the IP Address edit box. Verify that this address is correct. Use NI-488 Config to examine and adjust the configuration of the software. Refer to Chapter 6, GPIB Configuration Utility, in the NI-488.
Appendix B Troubleshooting and Common Questions What do I do if I have installed NI-488.2 and now my Macintosh crashes upon startup? Try changing the name of the NI-488 INIT to ZNI-488 INIT. Because INITs load in alphabetical order, the ZNI-488 INIT will load last, preventing possible corruption from INITs that load after it. If changing the name of the NI-488 INIT does not solve the problem, another INIT file might have a conflict with the NI-488 INIT. Try removing some of your other INIT files.
Appendix B Troubleshooting and Common Questions Why does the NI Ethernet Device Configuration utility list my box as *BUSY* when I know my network uses DHCP? For up to one minute, the GPIB-ENET/100 attempts to retrieve network parameters from a DHCP server. During this time, *BUSY* appears in the 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.
Appendix B Troubleshooting and Common Questions When should I use IBIC 488.2? You can use IBIC 488.2 to practice communication with your instrument, troubleshoot problems, and develop your application program. For more information about IBIC 488.2, refer to Chapter 4, Interface Bus Interactive Control Utility, in the NI-488.2 User Manual for MacOS. How do I use an NI-488.2 language interface?
