834RDA
SPECIFICATIONS
ORDERING
INFORMATION
The
Tektronix
834RDA
is
the
tool
that
gives
users
the
ability
to
auto—
mate
and
extend
the
capabilities
of
the
834
through
use
of
ROM
packs.
The 834RDA supports the genera—
tion of user—defined programs, set—
ups, and messages. The 834RDA
also aids the user in extending the
Baud,
Code,
Idle
and
transfer
function
directory
menus
by
adding
new
menu entries.
PROM‘s
are
developed
by
building
a
ROM
image
in
the
834
system.
The
834RDA
uses
the
RS—232
port
on
the
834
to
interface
to
an
exter—
nal
PROM
programmer,
a
printer
or
terminal,
or
a
unit
under
test.
The
834RDA
and
834
are
used
with
an
external
PROM
programmer
to
read
and
write
PROMs.
A
terminal
or
printer
used
with
the
system
produces
formatted
listings
of
the
ROM
image
contents.
With
the
834 connected
to
the
unit
under
test,
the
ROM
image
can
be
executed
to
verify
operation
and
correctness.
A ROM header name is generated
from
the
user‘s
input.
All
other
header
and
trailer
information
is
automatically
supplied
for
individ—
ual
entries
and
the
entire
ROM
image.

ROM
DEVELOPMENT
AID
The:
834RDA
includes
two
addition—
al
Code:
menu
items.
The
KEYS
translation
code
produces
a
one—
character
representation
of
each
key,
and
is
used
when
editing
key
sequences.
The
DISPLAY
transla—
tion
code
makes
all
834
display
characters
available
to
the
user
for
building
new
code
translation
tables.
Extended
instructions
that
are
in—
cluded
in
most
other
834RXX
ROM
Packs
are
available
to
the
user
in
the
834RDA
(see
Table
1).
Functions
of
the
ROM
Development
Aid
Save—Setup
Function.
The
Save—
Setup
function
generates
a
se—
quence
of
keystrokes
that
will
re—
create
any
of
the
834
menu
lists
including:
setup
menus,
simula—
tion
programs
(including
message
strings
and
parameters),
trigger
strings,
monitor
programs,
bit
er—
ror
rate
test
setups
and
message
strings.
The
Save—Setup
function
is
the
easiest
method
of
creating
and
storing
key
sequences
that
pertain
to
only
a
single
menu
list.
Record
Mode.
The
Record
mode
of
the
834RDA
enables
the
user
to
record
keystrokes.
In
this
mode,
all
keystrokes
are
recorded
in
the
order
.that
they
are
entered
until
the
exit
command
is
executed.
Af—
terwards,
the
keystroke
sequences
may
be
edited..Record
mode
is
a
simple
method
of
recording
user
setups,
programs
and
message
strings,
particularly
those
which
in—
volve
more
than
one
simple
setup
or
program
entry.

Form
Entry
Functions.
New
en—
tries
may
be
added
to
the
ROM
image
using
the
Form
Entry
func—
tions.
Two
types
of
entries
may
be
created:
menu
additions
(baud
rates,
translation
codes,
directory
entries
and
sync
idle
characters)
and
keystroke
sequences
(power—
up
and
normal,
and
character
strings).
Input—Output
Functions.
The
834RDA
system
can
accept
input
from
any
PROM
burner
that
sup—
ports
the
TEKHEX
format
and
has
an
RS—232
interface.
Error
detec—
tion
checks
are
made
to
assure
correct
image
transfer
from
the
PROM
Programmer
to
the
834.
The
ROM
image
contains
all
of
the
com—
pleted
entries
plus
the
appropriate
"overhead"
data
such
as
header,
trailer,
byte
counts
and
checksum
information.
Upon
completion
of
new
entries
or
changes
to
the
ROM
image
contents,
the
834RDA
De—
velopment
Aid
can
send
the
com—
pleted
ROM
image
back
to
a
PROM
burner.
A
listing
of
the
entire
ROM
image
or
of
individual
entries
can
be
sent
to
a
printer
or
terminal
for
docu—
menting
purposes.
The
834
must
be
in
DTE
SIM
or
DCE
SIM
mode
when
using
exter—
nal
equipment.
The
mode
setting
should
be
compatible
with
the
equipment
being
used,
i.e.,
DCE
SIM
when
interfacing
a
printer,
PROM
burner
or
DTE
under
test;
DTE
SIM
when
interfacing
modems
or
other
DCE.
Program
Debug
Functions.
The
program
debug
functions
con—
tained
in
the
834RDA
enable
the
user
to
interrupt
an
executing
834
program,
cause
single—step
pro—
gram
execution;
set
a
breakpoint
and
display
or
change
program
steps,
parameters,
and
messages.
It
is
also
possible
to
get
a
listing
of
the
current
Simulation
Program
(program
steps
messages
and
para—
meters).
See
figure
1.
Program Enhancement Capabili—
ty.
Two
new
functions
are
availa—
ble
for
assistance
when
creating
simulation
programs
with
the
834RDA; one function enables the
user
to
insert
a
step
in
a
program,
the other will delete a step. In both
cases,
the
remaining
program
steps
will
be
renumbered,
and
all
jump
instructions
will
be
adjusted
accordingly.
Additional
Information
The
834RDA
Development
Aid
is
compatible
with
several
PROM
burners.
The
PROM
burners
must
have
an
RS—232
interface
port,
and
must
support
Tektronix
Hexadeci—
mal
(TEKHEX)
transmission
format—
ting.
Some
examples
of
834RDA
compatible
PROM
burners
are:
* Tektronix 8550 Microprocessor
Development
Lab
* Data I/O System 19
*
Data
1/0
System
17
(with
either
TEKHEX
transmission
format—
ting,
or
remote—control
setup
capability)
*
PROLOG,
M980
(requiring
an
RS—232
adapter)
The 834RDA should be used with
an
834
that
has
level
04
(or
higher)
software. Software level can be
verified as follows:
Place the 834 in Self—Test mode.
Scroll
down
two
levels
to
the
LIST—DSROM
display.
*
Move
over
one
entry
to
LIST—
CSROMO.
Press the Start key.
The display will read "CSROMO:
PN
=
0836—04"
or
similar.
This
readout
is
the
end
of
the
part
number
of
the
ROM
containing
the pertinent 834 software. The
last two digits (software level)
should
be
04
or higher.
A
level
04
or
higher
ROM
is
supplied
with
each
RDA
in
case
it
is
needed.
If
the
ROM
is
not
needed,
it
can
be
erased
and
used
for
recording
custom
routines.
The
standard
Tektronix
Warranty
(one
year)
applies
to
the
834RDA.
Contact your local Tektronix
Sales
or
Service
Center
if
any
additional
information
or
updates
are required.

INTRODUCTION
The
834RDA
ROM
Pack
gives
you
the
capability
of
developing
your
own
spe:—
cial—purpose
ROM
packs
for
use
with
the
834.
A
customized
ROM
Pack
might
consist
entirely
of
user—defined
ROMs,
or
some
combination
of
user—
and
Tektronix—defined
ROMs.
Either
way,
in—
stallation
of
an
RDA
ROM
Pack
enables
you
to
use
the
834
as a
tool
for
develop—
ing
its
own
ROM
extensions.
Creating
a
custom
ROM
requires
not
only
an
834
equipped
with
an
RDA
ROM
Pack,
but
an
834—compatible
PROM
programmer
for
burning
the
cus—
tom
ROM
image
into
the
ROM
chip.
The
PROM
programmer
must
have
RS—232
interface
capability,
and
must
support
Tektronix
Hexadecimal
(Tekhex)
trans—
mission
formatting.
Some
examples
of
834—compatible
PROM
programmers
are:
*
The
DATA
I/O
System
19,
requiring
a
serial
interface
format
option.
*
The
DATA
I/O
System
17,
configured
either
for
Tekhex
transmission
formatting
or
for
remote—control
setup.
*
The
Pro—Log
M980,
requiring
an
RS—232
interface
adapter.
*
The
Tektronix
8550
Microprocessor
De—
velopment
Lab
with
PROM
programmer
option.
Using
the
RDA
requires
a
data
link
(see
figure
1)
between
the
834
and
a
compati—
ble
PROM
programmer.
Specifically:
*
Customizing
a
ROM
requires
the
ability
to
(a)
transmit
the
custom
ROM
image
from
834
to
PROM
programmer,
and
(b)
burn
the
image
into
the
ROM.
*
Editing
a
ROM
further
requires
the
ability
to
(c)
copy
the
ROM‘s
contents
into
the
PROM
programmer,
and
(d)
transmit
the
ROM
image
from
pro—
grammer
to
834.
All four operations involve special proce—
dures that vary from one PROM program—
mer
to
another.
For
a
summary
of
these
special procedures, refer to the section
pertaining to your PROM programmer.
Be sure to observe all manufacturer pre—
cautions
when
handling
IC
parts.
ROMs
can
be
damaged
by
static
discharge
or
improper
insertion
in
a
PROM
programmer.
All descriptions of PROM programmer op—
erations
pertain
only
to
product
versions
mentioned
in
this
document.
