PXI-8150 Series User Manual
•
The USB connector connects the chip set to the Universal Serial
Bus interface.
•
The PXI connector connects the PXI-8150 to the PXI/CompactPCI
backplane.
•
The Keyboard/Mouse block contains the PS/2 keyboard and mouse
interface.
•
The BIOS/RTC block contains the boot BIOS and the Real Time
Clock interface.
The daughtercard module has the following logic blocks:
•
The Ethernet block on the PXI-8156 is an ISA-based Ethernet
circuit. It uses an RJ-45 connector for access to an external
Ethernet-based LAN.
•
The GPIB logic block represents the IEEE 488.2 port on the
PXI-8156 model. It uses the National Instruments TNT4882 ASIC
for maximum performance as an ISA-based GPIB controller.
•
The PC Peripherals blocks represent the other peripherals supplied
by the PXI-8150 Series. The PXI-8155 has one serial port, an
ECP/EPP parallel port, and a 1.44 MB, 3.5 in. floppy drive. The
PXI-8156 adds a second serial port.
•
The IDE block is dedicated PCI-IDE circuitry providing fast
ATA-3 transfers to the internal hard drive. The IDE feature is built
into the chip set.
