Configuration Switch Settings For Sw1 - National Instruments GPIB-SCSI-A Getting Started

Chapter 2 Installation
The only parameters available for configuration with this kit are the SCSI ID and the
Note
GPIB address. Do not change any other switch settings from the factory default settings.

Configuration Switch Settings for SW1

GPIB-SCSI-A for Solaris
The GPIB-SCSI-A is shipped from the factory configured to operate
in SCSI (S) mode. 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 terminating resistor installed. Depending
on how you connect the GPIB-SCSI-A to your system, you may want
to remove the terminating resistor.
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 last time you booted with the following command:
dmesg
Among the startup messages are the devices found on the SCSI bus
and their respective Target ID numbers. If a Target ID of 5 is not available
in your system, select an unused Target ID (a number between 0 and 7)
and set the appropriate switch to that Target ID number (refer to the next
section, Configuration Switch Settings for SW1). Typically, Targets 1 and 3
are used by the internal disks, Target 4 is used by a tape drive (if you have
a tape drive), and Target 0 is used by an external disk drive. Target 7 is
always used by the Sun SPARC system central processing unit.
The DIP switch at location SW1 on the rear panel (see Figure 2-1) is used
to configure the power-on primary GPIB address and SCSI ID of the
GPIB-SCSI-A. Figure 2-2 shows the factory default settings.
