Bus Timeout (BTO) on the E8491B to 'Off' (see "Editing the
HP E8491B 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 E8491B is set to 'On'.
If you are using the E8491B in a configuration with multiple mainframes
linked with VXI-MXI extender cards, the E8491B must be the resource
manager; however, VME Bus Timeout (BTO) must be disabled (off - Step
4 above). Again, the E8491B 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 E8491B is
installed.
•
If you are installing the IEEE 1394 interface 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."
Generally, any VXI instrument can be installed in any slot other than slot 0.
When installing instruments, notice that the E8491B 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.
