If you want the E1406 to provide slot 0 functionality in addition to providing an
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 the E1406 servant area to include the logical addresses of those instruments it is to control. Note:
E1406 servant area = (E1406 logical address + 1) through (E1406 logical address + servant area switch setting)
6.Install the E1406 in slot 0.
If the E1406 is not the slot 0 device, its slot 0 functionality must be disabled. From step 2 above, set the E1406A Slot 0 and System Controller switches to “Disable”. From step 4, set its VME BTO Disable switch 1 and ensure that VME Bus Timeout (BTO) on the E8491A is set to ‘On’.
If you are using the E8491A in a configuration with multiple mainframes linked with MXI extender cards, the E8491A must be the resource manager; however, VME Bus Timeout (BTO) must be disabled (off - Step 4 above). Again, the E8491A is generally installed in mainframe slot 0 so that it also provides the system’s slot 0 functionality. Refer to the MXI documentation for configuration guidelines based on where the E8491A is installed.
Where to go Next If you are installing the IEEE 1394 interface and your VXI system for the first time, continue with “Step 3: Installing VXI Instruments.” If your VXI instruments are already installed, proceed to “Step 4: Installing the HP I_O Libraries.”
Step 3: Installing VXI Instruments
Generally, any VXI instrument can be installed in any slot other than slot 0.
When installing instruments, notice that the E8491A and the IEEE 1394 bus do not extend the (VXI) backplane between frames in
