Page 3: Important Information
The AT-FBUS and PCMCIA-FBUS hardware are warranted against defects in materials and workmanship for a period of one year from the date of shipment, as evidenced by receipts or other documentation. National Instruments will, at its option, repair or replace equipment that proves to be defective during the warranty period. This warranty includes parts and labor. - Page 4 FCC/DOC Radio Frequency Interference Compliance This equipment generates and uses radio frequency energy and, if not installed and used in strict accordance with the instructions in this manual, may cause interference to radio and television reception. Classification requirements are the same for the Federal Communications Commission (FCC) and the Canadian Department of Communications (DOC).
- Page 5 This device complies with the FCC rules only if used with shielded interface cables of suitable quality and construction. National Instruments used such cables to test this device and provides them for sale to the user. The use of inferior or nonshielded interface cables could void the user's authority to operate the equipment under the FCC rules.

Page 13: Ni-Fbus Monitor Overview
This chapter contains an overview of the NI-FBUS Monitor. NI-FBUS Monitor Overview The NI-FBUS Monitor is a Win32 application you can use to monitor, debug, and analyze fieldbus data packets. The NI-FBUS Monitor detects communication on the bus, capturing data packets that are passed between fieldbus devices. -
Page 14: Recommended Minimum Platform
The NI-FBUS Monitor uses a lot of processor time and memory resources during data captures. Therefore, the recommended minimum platform for the NI-FBUS Monitor is a 66 MHz 486 processor with 8 MB of RAM. If you want to run the NI-FBUS Monitor on a slower platform, see the Improving Performance section in Chapter 4, How to Use the NI-FBUS Monitor. -

Page 24: Selecting The Interrupt Request Line
If there are no interrupt request lines available in your system, you can configure the AT-FBUS not to use interrupts by removing the jumper completely. If you remove the jumper, NI-FBUS periodically polls your board. By default, the AT-FBUS board uses interrupt request line 11. Figure 2-5 shows the setting for IRQ11. -
Page 25: Configuring The Software
If you are installing more than one AT-FBUS board, each board must be configured to use a unique IRQ level. The AT-FBUS requires the use of interrupts to work with your NI-FBUS Monitor software properly. Find the jumpers that set the interrupt request line. Refer to Figure 2-3, AT-FBUS Parts Locator Diagram. -

The asterisk indicates that, after several attempts, the monitor on the fieldbus interface could not pass the packet to the host application (the NI-FBUS Monitor). This problem might happen on slow PCs, such as 386 computers, but it rarely happens on 486 computers. If you see an asterisk, read the Improving Performance section in Chapter 4, How to Use the NI-FBUS Monitor. -
