SECTION 1 GENERAL DESCRIPTION
1.1 INTRODUCTION
This manual contains information on how to install and operate the 7064 in a VXlbus
environment. It describes the function of the 7064 under control by the 96 buffered I/O
lines, or via the 68000 bus lines.
1.2 GENERAL DESCRIPTION
The 7064 is a message-based development module made up of a removable message-
based interface, and a breadboard card consisting of seventy square inches of breadboard
area for prototyping and development of digital and analog circuits.
The user circuitry developed on the breadboard can be controlled either by the twelve
8-bit individually configurable ports, or via the 68000's bus directly. The upper half of
the 68000 address space is available on the Message-Based Interface module for user
development.
The breadboard area is the front two-thirds of the module, and consists of two separate
arrays with holes on .1 inch centers. The arrays are divided into group A and group B
areas. Each area is subdivided into lettered columns and numbered rows for user
convenience. There are two uncommitted power distribution grids in each array available
to the user. These grid planes may be connected to various power supplies provided by
the VXI backplane. These two layers are called "Top" and "Bot" (Bottom). There are
also two power planes dedicated to +5V and ground.
One Message-Based Interface module can control up to twelve breadboard cards via the
local bus (see VXlbus Revision 1.3 specs for definition), allowing one to design multiple
module VXlbus instruments using a single interface board. The Message-Based Interface
module must be installed on the left-most breadboard card.

SECTION 2 INSTALLATION
2.1 INTRODUCTION
This section describes the unpacking, inspection, set-up and installation of the Model 7064
development module in a C-size mainframe.
2.2 UNPACKING AND INSPECTION
The following parts constitute the 7064 Module P/N 70-0010-000:
Single-Slot Breadboard Module
Message-Based Daughter Board
7064 User Manual
P/N 70-001 1-000
P/N 70-0014-000
1. Before unpacking the 7064 module, check the exterior of the shipping
carton for any damage. If the shipping carton is damaged, inform the
carrier immediately.
2. Remove the 7064 module quid inspect it for damage. If any damage is
apparent, inform the carrier immediately. Retain shipping carton and
packing material for the carrier's inspection.
3. Verify that the pieces contained in the package you received match the
parts list shown above. Notify Racal Instruments if the module
appears damaged in any way. Do not attempt to install a damaged
module into a VXI chassis.
4. The 7064 module is shipped in an anti-static bag to prevent
electrostatic damage to the module. Do not remove the module from
the anti-static bag unless it is in a static-controlled area.
2.3 ADDRESS SWITCH SETTINGS FOR CONFIGURATION CONTROL
The 7064 has an internal 8-position address switch used to determine dynamic configuration
or static configuration. It is located on the top of the module accessible through the case. Any
setting other than 255 indicates static configuration.
Dynamic configuration is an optional alternative method of assigning logical address to
VXlbus devices, and is defined in detail in Section F of the VXlbus System Specification
Revision 1.4. In the ON position, the switch is set to logical 1, and in the OFF position to a
logical 0.
The user can select any logical address from I to 254 for static configuration.

NOTE
Logical address 0 is not allowed.
For dynamic configuration, set the address switch to 255.
NOTE
The 7064 Breadboard Module is shipped with the address set for
dynamic configuration. Refer to the Resource Manager's manual for
details about its addressing methods.
2.4 VXIBUS INTERRUPT HANDLER SETTING
One programmable interrupt line is provided on the 7064 module. This line is assigned by
using the assign interrupter line word serial protocol command (See Page 182 of Section E,
Revision 1.4 of the VXlbus Specifications). The Int_ID is set to 1.
2.5 7064 TO VXIBUS MAINFRAME INSTALLATION
The 7064 module is ready for operation when shipped. The address switch is set to 255 to
allow for dynamic configuration by the VXI Slot 0 Resource Manager. See Section 2.3 if
static configuration (any switch setting other than 255) is preferred.
To install the 7064 in a C-size VXI chassis, use the following instructions:
1. Ensure power is OFF.
Configure the interrupt daisy chain on the backplane to bypass empty slots,
per VXlbus specifications.
3. Remove the front cover of the VXI chassis, and slide the 7064 into the
appropriate slot with the LED's towards the top (or to the left when using a
horizontal chassis).
To ensure reliable VXlbus communications when using 7064 modules without a VXlbus
communications interface (i.e., 7064-6, 7064-7, and 7064-25 series), the user must note the
following. The VME Specification requires that the Interrupt Acknowledge (IACK) and
BUSGRANT (BG) signal lines be daisy-chained from slot-to-slot across the backplane. This
means that for each slot the BUSGRANT and IACK signals are input on Row A of the P1
2-2

connector and output on Row C of the P1 connector. When there is no VXlbus interface
installed in the 7064 module, the user must ensure that these signals are passed onto the next
slot. There are three ways this can be done, depending on the backplane installed in your
VXlbus chassis. You will need to consult the chassis manual to verify the type of backplane
you have.
SIGNAL P3 or P101 SHORT
BGOIN* and BGOOUT* Pin 4 Row B to Pin 5 Row B
BG ITN* and BGIOUT* Pin 6 Row B to Pin 7 Row B
BG2IN* and BG2OUT* Pin 8 Row B to Pin 9 Row B
BG3IN* and BG3OUT* Pin 10 Row B to Pin 11 Row B
IACKIN* and IACKOUT* Pin 21 Row A to Pin 22 Row A
1. VXlbus Backplanes with Bus Grant and Interrupt Acknowledge DIP
Switches. -The user must close the switches in the slot where the 7064 will
be installed.
2. VXlbus Backplanes with Active Automatic Daisy-Chain. - The Bus Grant
and Interrupt Acknowledge signals will be automatically passed to the next
slot. The user does nothing.
1
3. VXlbus Backplanes with Auto-Configuration P1 Connectors. - With this
style of connector, the BUSGRANT and IACK daisy-chains are broken as
soon as the module is installed in a slot. The user must reconnect the daisy-
chain in the 7064 module. This is done by shorting the pins on the P3 or J 101
connector as shown in Table 2.1 below.
Table 2.1 Signal Shorts For Chassis With Auto-Configuration P1 Connectors
Bus Granp (Part Number 401951-003) has been designed to perform this task and may be
ordered from the Racal Parts Department. The jumper should be located in P3 or J101, pins
1through 22 as shown in Figure 2.1.

2.6 POWER-UP SELF-TEST INITIALIZATION
Before turning on the VXlbus mainframe, make sure a Slot 0 with a Resource Manager is
present. Upon power-up of the system, the 7064 goes through the following power-up
sequence:
•The 7064 breadboard module has two LED's on the front panel - FAIL
and ACCESS. The LED functions are:
FAIL On during a self-test
Off when the self-test has successfully completed
ACCESS Blinks on when the VXIbus is accessing the module's
logical address
At power-up, the 7064 goes through a series of operations to ensure proper initialization and
establish the proper start-up state. A brief description of this power-up sequence follows.
2.6.1 Self-Test
Test s are performed on ROM, RAM, Non-Vol and the tinier to ensure they are operating
correctly.
2-4

2.6.2 Board ID Check
Each breadboard may have one or more board ID bytes selected by the user. The user selects
a port, a value and a mask if necessary. This information is stored into non-vol by the user
and verified during the power-up sequence. This check is bypassed if not specified by the
user.
2.6.3 Port Initialization
A111/0 ports configured as outputs are initialized to either all 0's or all l's during system reset
(jumper selectable on each breadboard). The user can also specify initial values for ports and
have them stored in Non-vol. If any of these values have been specified, they are set at this
point in the power-up sequence. The operation of the board ID is described in more detail in
Section 3.2.1
2.6.4 VXlbus Interface Initialization
At times, it may be desirable for the user to specify an initial value for one or more of the
VXlbus registers. For example, the user specifies a model code. This requires the new model
code to be placed in the "device-type" VXlbus register. The user can specify these values and
have them stored in Non-Vol. If any of these values have been specified, they are set up at
this point in the power-up sequence.
2.6.5 Debugger Initialization
If the debugger ROM is present, it requires initialization to be performed at this point.
2.6.6 Invoke User Routine
The user may want to gain control after the 7064 has been initialized, but before the main
loop starts running. The user can specify a vector for this power-up routine. This vector is
stored in non-vol. If the vector has been specified, the user's initialization routine is called at
this point.
NOTE
At this point, invoke the main routine if the main processing loop is not
desired.
2-5

At the conclusion of the self-test (less than 4.9 seconds), the FAIL LED should be
extinguished. An illuminated FAIL LED is an indication of a module failure. If this occurs,
the module should be removed from the VXlbus chassis, and examined for damage or
improper installation.
2.7 LOCAL BUS USAGE WITH 7064 BREADBOARD
The VXlbus has a provision for interconnecting adjacent cards through a local bus. The bus
consists of 12 lines which jumper card together. A card on the left of another will have
connections on the "C" side of P2 tied to the "A" side of P2 for the card to its right. (Refer
to the VXlbus specification for exact pinouts.)
2.8 INSTALLING THE VSD-1 SERIAL DEBUGGER
1. Remove the thirteen #4 x 1/4 inch and the three #2 x 3/16 inch screws
retaining the top cover of your breadboard module. Remove the cover
and set it aside.
2. Remove the EPROM located at Ul of the VXlbus interface hoard using
aPLCC extraction tool (i.e., Burndy P/N 855045). This EPROM must
be removed in order for the breadboard to function with a debugger
installed.
3. Remove the two #4 x 5/8 inch screws located between P100 and P102 of
the VXI interface board along with their two flat and two split lock
washers. Retain this hardware for use when the serial debugger assembly
is removed.
4. The serial debugger assembly is installed directly above the VXlbus
interface board. The two mounting spacers on the debugger assembly
should be aligned to the two mounting points where the screws that were
removed came from. Use the two #4 x 1 1/8 inch screws along with the
flat and split lock washers provided with the serial debugger to hold the
debugger in place.
5. If the debugger assembly is correctly situated, its P1 connector will align
directly above the VXlbus interface's P100 connector. Install the short
ribbon cable assembly between these two connectors, taking care to align
them correctly.
2-6

CAUTION
Incorrect installation of this cable can result in damage
to the debugger and/or VXlbus interface assemblies.
6. Locate the 9-foot cable and D-SUB connector supplied with the
debugger. Install the phone jack connector on the cable to the D-SUB
connector and the other end to P2 of the serial interface board. Note that
P2 is keyed.
The installation of the serial debugger is now complete. The cover of the breadboard cannot
be reinstalled while the serial debugger is in place, If the breadboard is installed in a chassis,
the slot to its right must be left open.
