Compliance

FCC/Canada Radio Frequency Interference Compliance*
Determining FCC Class
The Federal Communications Commission (FCC) has rules to protect wireless communications from interference. The FCC places digital electronics into two classes. These classes are known as Class A (for use in industrial-commercial locations only) or Class B (for use in residential or commercial locations). Depending on where it is operated, this product could be subject to restrictions in the FCC rules. (In Canada, the Department of Communications (DOC), of Industry Canada, regulates wireless interference in much the same way.)
Digital electronics emit weak signals during normal operation that can affect radio, television, or other wireless products. By examining the product you purchased, you can determine the FCC Class and therefore which of the two FCC/DOC Warnings apply in the following sections. (Some products may not be labeled at all for FCC; if so, the reader should then assume these are Class A devices.)
FCC Class A products only display a simple warning statement of one paragraph in length regarding interference and undesired operation. Most of our products are FCC Class A. The FCC rules have restrictions regarding the locations where FCC Class A products can be operated.
FCC Class B products display either a FCC ID code, starting with the letters EXN, or the FCC Class B compliance mark that appears as shown here on the right.
Consult the FCC web site
http://www.fcc.gov

GPIB Hardware Overview

The GPIB-SCSI-A is a high-performance interface product that transparently handles data transfers between the SCSI and the GPIB. The GPIB-SCSI-A is actually an 8-bit microcomputer that operates as a full-function IEEE 488.2/SCSI Controller. It can turn any computer with a SCSI port into a GPIB Talker/Listener/Controller or it can make any device on the SCSI bus look like a GPIB device.
The GPIB-SCSI-A has all the software and logic required to implement the physical and electrical characteristics of the ANSI/IEEE Standard
488.2-1987 and the ANSI Standard X3T9.2. It is able to interpret and execute commands that you send to it over the GPIB or SCSI ports and to perform all necessary GPIB-to-SCSI protocol conversions.
Standard GPIB cables can connect the GPIB-SCSI-A with up to 14 devices. If you need to connect to more than 14 devices, you can add them to your system using an IEEE 488 extender or expander, such as the National Instruments GPIB-130, GPIB-120A, or GPIB-140A. Refer to Appendix B,
Specifications, for more information about the GPIB hardware
specifications and recommended operating conditions.

NI-488.2 Overview

NI-488.2 forSolaris consists of a loadable driver and utilities that transform a Sun SPARC system running Solaris into an IEEE 488.2 (GPIB) Controller with complete communications and bus management capabilities.
NI-488.2 includes the following components:
C language interface
Software diagnostic utility
Interactive control utility
Interactive configuration utility
NI-488.2 supports multiple GPIB-SCSI-A boxes installed in a Sun SPARC system, and is completely compatible with both IEEE 488 and IEEE 488.2 instruments.

Configuring the Hardware

The hardware configurations of the SCSI ID (Target ID) and the GPIB primary address must match the software configuration in the system configuration files and the NI-488.2 software.
The GPIB-SCSI-A is shipped from the factory with a 100-120 V or a 220-240 V power supply. Before you use the GPIB-SCSI-A, verify that the voltage on the power supply matches the voltage that is supplied in your area.
Caution

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

Configuration Switch Settings for SW1

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.

Using SCSI Terminating Resistors

Because of its high-speed capabilities, the SCSI bus is sensitive to the electrical characteristics of the SCSI cabling. When a signal is sent through the SCSI bus, it bounces back and creates echoes along the cabling. Any device in the middle of the daisy-chained SCSI bus receives these signal echoes. You should use terminating resistor packs to prevent echoes and ensure proper termination of a signal. 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. Also, ensure that the device at the other end of the SCSI bus (for example, the SCSI host in Figure 2-4) has a terminating resistor installed. Remove the terminating resistor packs on all devices except for the one at each end because SCSI signals are not reliably passed along the SCSI bus after they reach a device with a terminator.
Caution
Never connect more than two sets of terminating resistors on an SCSI bus because
more than two sets might overload the signals and generate errors.

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 2-5) do not have terminating resistors installed. The devices at each end of the SCSI bus should have terminating resistors installed.

Connecting the Hardware

The following are general instructions for connecting the GPIB-SCSI-A to the Sun SPARC system. Consult the chapter on installing external drives in the installation guide that came with your 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. Daisy-chaining is a means of connecting a number of SCSI devices to a host; thereby, a single port on the host can serve a variable number of devices. Daisy-chaining is the suggested method for connecting the GPIB-SCSI-A to the Sun SPARC system.

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 terminating resistors should be installed on both ends, as described earlier in this chapter.
2. Connect the GPIB cable to the GPIB-SCSI-A and tighten the thumb screws on the connector. Connect the other end to your GPIB system. Be sure to use only shielded GPIB cables. Total cable length in your GPIB system should be less than 20 m, with a maximum separation of 4 m between any two devices. You should have no more than 15 devices in a GPIB system, and at least two-thirds of those devices must be powered on.
3. Plug the power cord into an AC outlet of the correct voltage.
