Getting Started
Getting Started
Product Description
This chapter begins with a brief description of the 73A-851A Adapter Module,
and explains how to configure and install the module in a VXIbus mainframe.
The 73A-851A Adapter Module is a printed circuit board assembly for use in a
mainframe conforming to the VXIbus specification. This module is an active
extender board that allows double height VME modules or B size VXI modules
to be installed in a C size VXI mainframe. The 73A-851A is installed in a single
slot of the VXI mainframe. A VME or VXI module is then installed into the
73A-851A. The 73A-851A detects whether the installed module is acting as a
bus master or slave and transceives the backplane address bus, data bus and
control bus signals accordingly. Proper VMEbus timing and signal loading are
maintained on the VXIbus and at the installed module backplane connectors.
The 73A-851A is form, fit, and function equivalent to the 73A-851 except that
the 73A-851A supports A24/D64 and A32/D64 Multiplexed Block Transfers
(MBLT).
Pins in rows A and C of backplane connector P2 are classified as user definable
in the VMEbus specification. The VXIbus specification fully defines the usage
of these pins. Since the VXIbus pin definitions may conflict with the pin
definitions of a VME module, the standard 73A-851A isolates pins in rows A
and C of backplane connector P2 from the corresponding pins on an installed
VME module.
The 73A-851A option 02 is an assembly consisting of a single wide front panel
and two ribbon cables. The two ribbon cables are terminated with “D” style 37
pin connectors located on the front panel. The opposite end of the two ribbon
cables are connected to the VME module HEADER A and HEADER B
connectors (refer to Figure 2–1). These headers are electrically connected to the
VME module P2 connectors rows A and C. The 73A-851A Option 01 includes
these ribbon cables and jumper blocks.
When a VXI module is installed in the 73A-851A, pins in rows A and C of
backplane connector P2 are connected directly to the corresponding pins on the
VXI module. These connections are made by installing ribbon cables and power
jumper blocks onto the 73A-851A. The 73A-851A Option 01 includes these
ribbon cables and jumper blocks.

Installation Requirements and Cautions
The 73A-851A Module is a C- size VXIbus instrument module and therefore
may be installed in any C- or D- size VXIbus mainframe slot other than Slot 0. If
the module is being installed in a D- size mainframe, consult the operating
manual for the mainframe to determine how to install the module in that
particular mainframe.
NOTE. The following system-level restriction must be observed when using the
73A-851A Module.
If a bus master is installed in the 73A-851A, the 73A-851A must be installed in a
slot to the right of any other bus master that issues bus requests on the same
level as the bus master installed on the 73A-851A.
Getting Started
Tools Required
The following tools are required for proper installation:
Slotted screwdriver set.
NOTE. In order to maintain proper mainframe cooling, unused mainframe slots
must be covered with blank front panels supplied by the mainframe
manufacturer.

Switches
This chapter describes the 73A-851A controls.
The following controls are provided to select the functions of the 73A-851A
Module operating environment (See Figure 2–1 for their physical locations).
Interrupt Select Switch
TTL Trigger Direction
Switches
The 73A-851A has an Interrupt Select switch for each interrupt level on the
VXIbus. These switches determine whether the installed module is to act as an
interrupt handler or as an interrupter for each of the VXIbus interrupt levels,
IRQ1* through IRQ7*.
If an Interrupt Select switch is set to position 1, the module installed in the
73A-851A may be an interrupt handler on the corresponding interrupt level but
may not be an interrupter on that level.
If an Interrupt Select switch is set to position 2, the module installed in the
73A-851A may be an interrupter on the corresponding level, but may not be an
interrupt handler on that level.
If the installed module is neither an interrupter nor an interrupt handler on a
particular interrupt level, the switch position for that level has no effect.
The 73A-851A has a Direction switch for each VXIbus TTL trigger line, which
must be set if a B size VXIbus module is installed in the 73A-851A. These
switches correspond to VXIbus signals TTLTRG0* through TTLTRG7*.
If a Trigger Direction switch is set to position 1, the corresponding VXIbus
trigger signal is an input to the module installed in the 73A-851A. If a Trigger
Direction switch is set to position 2, the corresponding VXIbus trigger signal is
an output from the installed module.
If the installed module does not monitor or drive a particular TTL trigger signal,
the switch position for that signal has no effect.
ECL Trigger Direction
Switches
73A-851A VME to VXI Adapter Module

Appendix C: Troubleshooting Procedure
If a VME module installed in the 73A-851A module does not function properly,
use the following procedure before consulting the Tektronix field office or
representative:
VME modules must not be placed in the upper quarter of A16 address space
(0C000h through 0FFFFh with address modifiers 29h or 2Dh). Also verify that
any A24 or A32 address space used by the module does not coincide with
address space assigned to a VXIbus module installed in the system.
1. Check the switch settings on the 73A-851A Module. These settings must be
set according to the capabilities of the installed module. For example, if the
installed module generates interrupts on VME level 3, the IRQ3* switch on
the 73A-851A Module must be set to position 2.
2. Check the jumper positions on the 73A-851A Module. The three P2 power
jumper blocks must be removed if a VME module is installed in the
73A-851A.
3. If the 73A-851A switch settings and jumper positions are correct and the
module still does not function properly, remove the module from the
73A-851A module and install it on a VME extender board. If a VME
module is being used, be sure to isolate the VME module from P2 rows A
and C.
4. If the module functions properly after following step 3, call the Tektronix
field office or representative for help in resolving the problem that appears
when the module is installed on the 73A-851A.
5. If the module still does not function properly after following step 3, recheck
the switch settings and jumper positions on the module. Contact the
manufacturer of the VME module if the module settings are correct and the
module does not function on a passive extender board.
