HP / Agilent E8491B
The Agilent E8491B Firewire PC Link to VXI module is a high-speed
C-size device providing a direct connection from your PC to a VXI mainframe with Resource Manager and Slot 0
capability. Its logical address is 0, therefore it is always the mainframe’s Resource Manager and is typically
installed in mainframe Slot 0. The high speed is accomplished, in part, through the use of small signals (200
mV) that are transmitted differentially over the twisted-pair wire set with controlled-impedance characteristics.
The differential signal provides high-noise immunity.

The E8491B is well suited for data acquisition applications moving
large blocks of data, and it is a cost-effective choice for test applications when used with Agilent’s E84XX
mainframe series. For multiple VXI mainframe systems, one E8491B is installed into each mainframe and these
are interconnected via the cable in a daisy-chain, tree or star configuration. Up to 16 mainframes can be supported
from one PC. This reduces the system cost further since an additional OHCI-based IEEE-1394/PCI card is not needed
for each added mainframe.
