Description
The Agilent Technologies E8491B IEEE-1394 PC Link to VXI
is a C-size, 1-slot, message-based VXI module, providing a
direct connection from your PC to a VXI mainframe via the
industry standard IEEE-1394 bus (FireWire).
The E8491B is a high-speed C-size device 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 includes a C-size VXI Slot 0 module and a 4.5-
meter cable. Ease of configuration is achieved with
automatic recognition of a new IEEE-1394-based device
without powering down the PC, known as “hot plug-in”.
The E8491B Option 001 is an OHCI-based IEEE-1394/PCI
host adapter card. It is a PC plug-in card capable of
transferring data at up to 400 Mbits/second. The card has
three external 1394 ports. If required, the OHCI-based
IEEE-1394/PCI card can supply 12V at up to 1.5A for
IEEE-1394 devices that require power.
