Chapter 1 Introduction Using the IEEE 1394 Serial Bus in VXI Systems The IEEE 1394 Serial Bus (FireWire) is a high-speed bus that has been implemented as an I/O interface between external PCs and HP VXI systems. The bus links the PC backplane to the VXI mainframe backplane. This manual describes the implementation, configuration, and use of this interface. Component Implementation of the IEEE 1394 serial bus as an I/O interface for HP VXI systems is provided through three components: Overv

If you want the E1406 to provide slot 0 functionality in addition to providing an HP-IB interface, set its configuration as follows: 1. Set the E1406 logical address to a value other than 0. 2. Set the Slot 0 and System Controller switches to “Enable” (default). 3. Set the CLK 10 source to “Internal” (default). 4. Set the VME BTO Disable switch to 0 - Enable (default). Set VME Bus Timeout (BTO) on the E8491A to ‘Off’ (see “Editing the HP E8491A Configuration” later in this chapter). 5. Set th
