Appendix B

Utilities

This appendix contains information on the IPassign and Update utilities for the

GPIB-ENET.

IPassign Utility

If your network does not have RARP capabilities, you can use the IPassign utility to configure the IP address for the GPIB-ENET. Before using this application, make sure that you know the Ethernet address of the GPIB-ENET, which is listed on the bottom panel of the box, and the IP address that has been selected for the box. The IP address should be a unique IP address not yet used within your network or domain. If you do not know the IP address, see your network administrator. Once you configure the IP address, it is stored in nonvolatile memory in the GPIB-ENET.

You should run the IPassign utility only when the box is new or when you decide to reconfigure your network in a way that changes the IP address of the GPIB-ENET.

Because of protocol limitations, this utility must be run from a Macintosh with an

Ethernet port. This utility does not work from LocalTalk.

To run IPassign , follow these steps after you have connected the GPIB-ENET to the network and installed the NI-488.2 software.

1.

Make sure that you configure the DIP switches properly. Switch 6 should be OFF, indicating that you are going to configure a protocol address from the network.

Switch 5 should be ON, indicating that you are using IPassign to configure the

IP address. Switches 8, 7, and 4 through 1 should all be OFF.

2.

Power on the GPIB-ENET.

3.

Change to the folder that contains the NI -488.2 distribution files.

4.

Execute the IPassign utility, which is located in the Ethernet folder.

a.

Select an Ethernet interface to use by clicking on the appropriate dialog button.

b.

Enter the IP address that has been selected for the box. En ter the IP address in standard notation, which is four decimal numbers separated with periods.

c.

Enter the physical Ethernet address for the GPIB-ENET. This is the address shown on the identification label on the bottom panel of the GPIB-ENET. Enter the Ethernet address in standard notation, which is six hexadecimal numbers separated with colons.

B-1 GPIB-ENET for Macintosh

Utilities Appendix B d.

IPassign constructs 10 reply packets and sends them across the local

Ethernet. When the GPIB-ENET successfully receives its IP address, the

READY LED remains steady. As long as the READY LED is flickering, the address has not been configured.

Because the reply packets do not form a guaranteed delivery protocol, it is possible (though extremely unlikely) for all 10 packets to get lost in the network and for the GPIB -ENET not to receive any of them. In this case, rerun the utility until the GPIB-ENET successfully receives its new IP address.

5.

When the READY LED remains steady, power off the GPIB-ENET and set DIP

Switch 6 to the ON position. With the switch in this position, the GPIB-ENET powers on at the IP address configured in Step 4, which is stored in nonvolatile memory. If Switch 6 is ON, the position of Switch 5 does not matter.

6.

Power on the GPIB-ENET and wait for the READY LED to come on and remain steady.

Update Utility

If you have received your NI-488.2 software as an update to your current GPIB-ENET, you need to update the firmware in the GPIB-ENET. Electrically Erasable

Programmable Read Only Memory (EEPROM) stores the firmware that controls the

GPIB-ENET. You can use the Update utility to upgrade the firmware in the EEPROM.

The latest firmware file is called GPIBENET_EPROM xx , where xx stands for the latest firmware revision number.

Caution: Please read this entire section before attempting to update your firmware.

If you are directly linked to the Internet, and not just to an isolated network using IP protocols, you can contact the National Instruments GPIB Product Support Department to update your firmware. If you are not on the actual Internet or you want to update the firmware yourself, you can execute Update locally. In either case, pay close attention to the GPIB-ENET READY LED, which reports important status codes.

Although you should update your firmware as needed, the number of times you can do so is limited. Therefore, you should update the firmware only when necessary. Also, notice that there is a time period of about two seconds when the GPIB-ENET runs exclusively in volatile RAM memory with the EEPROMs erased. If the box loses power during this time, it is no longer usable and must be returned to National Instruments for repair. If you are not comfortable with this procedure, call National Instruments for assistance.

Caution: Because of the potential loss of EEPROM information, do not attempt to update the firmware when your electrical power is in danger; that is, during a weather storm or similar situation. Once you have started the update process, do not switch off power to your GPIB-ENET until you see

and record the flashing READY LED pattern.

Appendix B Utilities

The following procedures describe how to update the firmware.

1.

Power off the GPIB-ENET and set DIP switch 7 to the ON position.

2.

Power on the GPIB-ENET and wait for the READY LED light to remain steady without flashing.

3.

Execute the Update application, which is located in the Ethernet folder.

a.

Enter the IP address of the GPIB-ENET in the space provided, and click on the

Done button to continue.

b. Select a GPIB-ENET EEPROM file to use as the firmware image.

After the GPIB-ENET receives the firmware image, the Update utility reports the status of the download. At that point, the network connection is closed.

Therefore, the utility does not report the success or failure of the actual

EEPROM programming, but only of the transfer of the firmware image.

c.

After the connection terminates, the GPIB -ENET attempts to program its

EEPROMs. Wait for the READY LED to begin flashing, which signals that the procedure is complete. Do not power off your GPIB-ENET before you see and record the flashing READY LED pattern.

If the programming is successful, the READY LED signals a status code of 00, signified by one long flash and one short flash. Other patterns are used to indicate that the EEPROMs did not program properly. If a pattern other than 00 is indicated, make note of the flashing pattern before switching off the

GPIB -ENET, and contact National Instruments for further assistance. Refer to the section READY LED Signaling in Chapter 4, Installation Verification and

Troubleshooting, for more information on recording the flashing pattern.

4.

Power off the GPIB-ENET and return DIP switch 7 to the OFF position.

5.

Power on the GPIB-ENET and wait for the READY LED to remain steady without flashing.
