NI-488.2 for Solaris ™ This document describes how to configure and connect the GPIB-SCSI-A to your Sun SPARC system and how to install NI-488.2 for Solaris. The NI-488.2 software included in this kit is intended for use with Sun SPARC systems running Solaris 2.6 or later.
Optional parity checking on the SCSI port is disabled. The SCSI ID that the GPIB-SCSI-A responds to is set at 5, and the primary GPIB address is set at 0. Additionally, the GPIB-SCSI-A kit is shipped from the factory with a SCSI Installing Your GPIB-SCSI-A and NI-488.2 for Solaris...
SCSI ID (Target ID) and the GPIB address. Do not change any other switch settings from the factory default settings. The factory default setting of the GPIB-SCSI-A Target ID is 5. To confirm that a Target ID of 5 is available in your system, print out the startup messages from the...
The DIP switch at location SW2 on the rear panel in Figure 3 is used to configure the mode of operation for the GPIB-SCSI-A. These switch settings should not be changed for use with the Sun SPARC system. Figure 3 shows the factory default settings.
Sun SPARC system for specific instructions and warnings. There are two methods for connecting the GPIB-SCSI-A to the Sun SPARC system. One method is connecting the GPIB-SCSI-A directly to the Sun SPARC system unit by using a cable with the proper connectors at each end. The other method is daisy-chaining.
SCSI bus. Complete the following steps to connect the cables: 1. Connect the SCSI cable to the GPIB-SCSI-A and fasten it securely. Connect the other end to your SCSI system. Be sure to use only shielded SCSI cables. Total cable length in your SCSI system should be less than 6 m, and...
Read the documentation for each device in your system to find out what kind of termination it provides. If your GPIB-SCSI-A is located at the end of an SCSI bus, you can prevent echoes by leaving the terminating resistor pack installed on one of the ports on the rear panel of the GPIB-SCSI-A.

6 SCSI Host Figure 4. Location of Terminating Resistors for GPIB-SCSI-A at End of SCSI Bus If your GPIB-SCSI-A is not located at the end of the SCSI bus, remove the terminating resistor pack from the rear panel of the GPIB-SCSI-A. Also ensure that all other devices in the middle of the bus (for example, the SCSI disk drive in Figure 4) do not have terminating resistors installed.
Step 3. Switch On Your GPIB-SCSI-A Switch on your GPIB-SCSI-A by using the rocker switch on the rear panel. The POWER LED should come on immediately and the READY indicator on the front panel should come on after the GPIB-SCSI-A has passed its power-on self-test, indicating that the unit is ready for operation.
Removing NI-488.2 (Optional) If you ever decide to stop using your GPIB-SCSI-A, you can remove NI-488.2 from your system. To remove NI-488.2 from the kernel configuration, you must have superuser privilege and the driver must not be in use. Enter the following command to unload the software:...
NI-488.2M Software Reference Manual. What could be causing a problem if the installation process fails? The most probable reason is that the GPIB-SCSI-A is at a different SCSI Target ID than what you entered during installation. Reinstall using the correct ID.
