LA. is the Logical Address
In order to use and program the Option 01 daughter board in an IEEE-488
environment you must know the IEEE-488 address of the module. Different
manufacturers of IEEE-488 interface devices might have different algorithms for
equating a logical address with an IEEE-488 address. Consult the operating
manual of the IEEE-488 Interface Slot 0 module being used.
Each function module in a VXIbus System can generate an interrupt at a
specified level on the VMEbus to request service from the interrupt handler
located on its commander. Set the interrupt level to the same level as the
interrupt handler on that commander. The VMEbus interrupt level on which the
Option 01 daughter board generates interrupts is set by a rotary switch. Align the
desired switch position with the arrow on the module shield.
Valid VMEbus Interrupt Level Select switch settings are one through seven, with
setting one equivalent to level one, and so on. The level chosen should be the
same as the level set on the Option 01 interrupt handler, typically the module
commander. Setting the switch to zero or eight will disable the module inter-
rupts. Do not use switch settings nine through F.
Interrupts are used by the module to return VXIbus Protocol Events to the
module commander. Refer to the Operating Basics section for more information
on interrupts.
Installation
This section describes how to install the Option 01.
A Torx
t T-10 driver set is required for proper installation.
The Option 01 daughter board is installed on a C-size VXIbus instrument
module and therefore may be installed in any C- or D-size VXIbus mainframe
slot other than slot 0. To install the module in a D-size mainframe, consult the
operating manual for the mainframe. Refer to Configuration for information on
