For high-speed operation (100 K switches/sec.) the scanning list is automatically downloaded into RAM on the multiplexer module. Triggering for channel advance is from the two handshake lines on the digital bus. The scanning operation does not require any intervention from the mainframe CPU. This only applies for switchboxes or scanning voltmeter configurations that have all FET multiplexer modules. For a downloaded scan list in switchboxes, the trigger source must be TRIG:SOUR DBUS or TRIG:S

Switchbox and Scanning Voltmeter Configurations A VXIbus instrument is a module or group of modules which perform a specified function. For the HP E1300/01 mainframe, the first module in an instrument must have a logical address which is evenly divisible by 8 (16, 24, 112), and the rest of the modules in the instrument are numbered consecutively. The instrument’s secondary address is the whole number equal to the logical address divided by 8 (for a logical address of 16, 17, 18,…23, the second

The multiplexer(s) and the multimeter have the same secondary address. The multimeter automatically configures the multiplexer, so the SCAN:MODE, SCAN:PORT and TRIG:SOUR commands are not required. Channel advance is from the digital

Multiplexer Card Numbers HP plug-in modules installed in an HP VXIbus mainframe are treated as independent instruments each having a unique secondary HP-IB address. An instrument may be composed of a single plug-in module or multiple plug-in modules. The card number identifies the module within a switchbox or scanning voltmeter configuration. The multiplexer module with the lowest logical address is always card number 01. The multiplexer module with the next successive address is 02, and so o

Figure 2-3. Card Numbers for Scanning Voltmeter The logical addresses noted in Figures 2-1, 2-2, and 2-3 apply to modules installed in an HP 75000 Series B Mainframe (HP Model Number E1300A/E1301A) or in a mainframe with an HP E1405/1406 Command Module. See the HP 75000 Series B Installation and Getting Started Guide or the appropriate HP Command Module Manual for more information on switchboxes and scanning voltmeter configurations, and logical addressing. For uses in other systems or mainfra

Selecting the Interrupt Line Number The multiplexer module generates interrupts at the end of a downloaded scan list. The interrupt line number switch determines which backplane IRQ line will be used. Different mainframes and resource managers recognize different backplane IRQ lines. The interrupt line number must be set to the line number your system is programmed to recognize. Refer to your mainframe manual. Refer to Figure 2-5 to change the interrupt lines. Valid line numbers are from 1
