20 Interface Installation and Configuration Chapter 2
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 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 multi-frame VXI
systems (MXI cards are required). This means that the multimeter and
multiplexers in a VXI scanning multimeter for example, must be installed in
the same mainframe (in adjacent slots). Devices sharing the VXI Local bus
must also be installed in the same mainframe.
