The 1349A/D have an addressable resolution of 2048
by 2048 points which allows display of very high
quality images, composed of straight or curved lines.
Curved lines are formed by a series of short straight
vectors joined end to end. The unit has programmable
writing speeds and programmable intensities.Vectors,
regardless of length can be drawn atconstant speed so
that the intensity does not vary from vector to vector.
For on screen labeling andidentification, the 1349A/D
have a built-in set of ASCII characters. The 1349A/D
receive just one word from the user processor and all
the vectors necessary to form one character are
automatically produced from ROM.

2-11. ANALOG OUTPUTS (X-Y-Z).
The purpose of the Analog Output jacks on the X-Y-
Z/Stroke Generator (Al) board is to connect an
external X-Y-Zdisplay. Theoutput signalscan drive1V
p-p into 600 ohm loads. The bandwidth of the external
X-Y-Z display should have the following bandwidths:
X-Y Axis: >=3 MHz
Z Axis: >=lo MHz
The interface cables should not exceed 1.83m (6 ft) in
length. Use the following table for interfacing:
A1J3 ........ Z AXIS OUTPUT
A1J4 ....... Y AXIS OUTPUT
A1J5 ....... X AXIS OUTPUT
2-12. OPERATING ENVIRONMENT.
2-13. Temperature. The instrument may be operated
in temperatures from 0"
C to f65" C (+32" F to 149"F).
The airflow recommendations stated above
must be adhered to in order to prevent
damage to the instrument.
NOTE
The65" C (+ 149" F)temperaturespecification
reflects the maximum allowable operating
temperature with the 1349A/D enclosed, not
the ambient temperature of the system
housing. It is recommended that a minimum
of .84 m3/min(30ft3/min)of air flow is forced
around and through theinstrumentto ensure
that the maximum operating temperature of
65"
C (+14g0F) is not exeeded.
Ambient temperature measurements should be taken at
several points in the instrument. Use the following in-
formation as a guide for making these measurements:
Measure temperature at:
a. Between the High Voltage cover and
Focus Gain Adjustment.
b. 0.64 cm (0.25 in.) above A4R31.
c. Between Vector Processor Board (A2)
and the Memory Board (A5) near A2U16.
d. 0.64 cm (0.25 in.) above AlU23.
The surface temperature near AlU26 and AlU33
typically may be +50° C (+12Z0 F) or more above the
ambient temperature. It is therefore recommended that
heat-sensitive devices or circuits not
be placed in close
proximity to these points.
2-14. Humidity. The instrument may be operated in
environments with humidity up to 95%. However, the
instrument should also
be protected from temperature
extremes which cause condensation within the
instrument.
2-15. Altitude. The instrument may be operated at
altitudes up to 4 600m (15 000 ft).
2-16. STORAGE AND SHIPMENT.
2-17. Environment. The instrument may be stored or
shipped in environments within the following limits:
Temperature -40"
C to $70" C (-40"F to +158" F)
Humidity up to 95g1relative humidity at
+50° C (+122" F)
Altitude 15 300m (50 000 ft)
The instrument should also be protected from tempera-
ture extremes which causes condensation within the
instrument.
2-18. PACKAGING.
2-19. Original Packaging. Containers and materials
identical to those used in factory packaging are
available through Hewlett-Packard offices. If the
instrument is being returned to Hewlett-Packard for
servicing, attach a tag indicating the type of service
required, return address, model number, and full serial
number. Also mark the container FRAGILE to ensure
careful handling. In any correspondence, refer to the
instrument by model number and full serial number.
2-20. Other Packaging. The following general instruc-
tions should be used for repacking with commercially
available materials.
a. Wrap instrument in antistaticplastic. (If shipping
to Hewlett-Packard office or service center, attacha tag
indicating type of service required, return address,
model number, and full serial number).
b. Use a strong shipping container. A double-wall
carton made of 350-pound test material is adequate.
c. Use a layer of shock-absorbing material 70 to 100
mm (3 to
4 inches) thick around all sides of the
instrument to provide firm cushioning and prevent
movement inside the container. Protect control panel
with cardboard.
d. Seal shipping container securely.
e. Mark shipping container FRAGILE to ensure
careful handling.
f. In any correspondence, refer to instrument by
model number and full serial number.

3-1. INTRODUCTION.
3-2. The purpose of this section is to give detailed
information concerning the operation andprogramming
of the 1349A/D. It includes a list of the programming
instructions and a section containing a brief
explanation of "bit programming". The end of this
section contains several programming examples.
WARNING
SHOCK HAZARD
Before operatingtheinstrument,connect the
chassis of the display to a safety ground in
the system.
3-3. SIGNAL LINE DEFINITIONS.
DO-Dl5
DO through Dl4 are the vector data lines (TTL
positive logic). Dl5 is used as a Vector Memory
instruction.When Dl5isa"1" thentheinput datais
recognized as a memory command. When Dl5is a
"0" then all the input data forms the picture.
DISCONNECT SENSE
This line must be grounded to the display chassis
when the data lines are active. The internal
Performance Verification pattern will be displayed
if the 26-pin connector is disconnected.
SYNC
External display refresh synchronization signal
line. The line provides an external refresh clock
when external sync mode has been selected via a
jumper wire on the Vector Memory board.
LXACK
Acknowledge signal line. When low, this line
indicates that the Vector Memory has completed
the Read or Write operation requested by the user
processor.
LDS
Device Selectsignalline.When low thislineenables
the Vector Memory to communicate with the user
processor (write/read).
LWR
Memory Write signal line. When low, this line
indicatesthatthe 16-bitData Bus contentsaretobe
written into either the current Vector Memory
location (D15=0) or into the User Address Pointer
(D15=1).
LRD
Memory Read signal line. When low, this line
indicates that the contents of the current Vector
Memory location (asspecified by the UserAddress
Pointer) areto be placed on the 16-bitData Bus for
transmission back to the user processor.
NOTE
Whenever a Vector Memory location has
been either written into or read from by the
user processor, the User Address Pointer
auto-increments to the next Vector Memory
location (address).
3-4. HANDSHAKE TIMING FOR 1349D.
TheTTLdigital interfacetotheVector Memory (1349D)
is compatible with most microprocessor peripheral
interface adaptor chips (the Motorola
63 6821).
Vector Memory digital interface consists of:
1. A 16-bitbidirectional Data Bus.
2. A Read Signal line LRD (input).
3. A Write signal line LWR (input).
4. A Device Select signal line LDS (input).
5. An Acknowledge signal line LXACK (output).
6. An External display Synchronization signal line
SYNC (input use is optional).

FOR 1349D.
SWITCHES SET
FOR EXT SYNC
Each timethatthe picture is redrawnby the 1349D,the
display is refreshed. This prevents the phosphor light
output from expiring. The refresh sync signal may be
provided by either the internal refresh circuit, or an
external source.Toselecttherequired modeof operation
for refresh mode, set the Int/Ext switch (A5S1)on the
Memory Board (A5) asshown in figure 3-3.
INTERNAL SYNC. When the jumper is ir, the
Internal position, an on-board oscillator (A5U1)
provides syncpulses atapproximately a 60 Hzrate.The
user processor can sendallpicture producing datatothe
Vector Memory at one time. The Vector Memory will
then continuously refresh the display screen by
redrawing thepicture atregular intervals.Thisreduces
overhead time for the user processor.
the SYNC input signal line. This signal is useful when
the display is used in electromagnetic fields which can
causethe picture to "swim". Synchronizingthedisplay
with the interfering signal can stabilize the picture.
3-6. REFRESH MODES FOR 1349D.
The Vector Memory sends its data to the Vector
Processor (VPC)each timethepicture is tobe drawnon
screen. Data issend to theVPC either viasynchronous
mode or free running mode.
SYNCHRONOUS MODE. In synchronous mode, the
Vector Memory waits untila synchronizingpulseoccurs
before it will begin its next data output cycle to the
1349A/D. Synchronous refresh mode is entered when
the Refresh Pointer equals 8191. After sending the
contents of address 8191totheVPC,theVector Memory
waits for the next sync pulse before starting a new
refresh cycle at address
0000.
EXTERNAL SYNC. Sync pulses (?TL) must be
