If the 834 is turned on in the SELF TEST m ode and an error condit ion exists , the
power - up self test displays the appropriat e error m essage . In any ot her m ode , the
display reads 834 ERROR . In this case , the operat or should turn the 834 off ,
change the m ode set t ing to SELF TEST , and turn the 834 on again to see the
specific
error
m essage .

If one of these m essages is displayed , turn the 834 off , rem ove the ROM pack from the
connector in the back of the 834 , then turn the test er on again . If this does not rem edy the
problem , refer the ROM pack to a qualified servi ce technician .
The 834 offers a LIST ROM rout ine as a part of the SELF TEST m ode . This rout ine displays
descript ive dat a on any ROM in the 834 and is useful for verifying that the correct int ernal

OPERATING
INSTRUCTIONS
CHARACTER
ASYNCHRONOUS
AND
BLOCK
ASYNCHRONOUS
The
834 supports
two types of
asynchronous
t ransm issions
: "
character
asynchronous
"
and
"
block
asynchronous . "
Most
ASCII
asynchronous
t erm inals
use
character
asynchronous
t ransm issions . In
this
type
,
characters are
received at
varying
int ervals ,
and
fram es are
t erm inat ed by
a
single End of
Fram e (
EOF
)
character ( line
feed
or
carriage
return
)
.
Charact er
asynchronous appears in the set up m enu as SETUP = ASYNC .
C
Block
asynchronous
t ransm ission
is
used
with
line
protocols that
process
characters in
groups or blocks . The end of a block is determ ined either by an EOF character or an idle line .
Block
asynchronous
appears in the
set up m enu as
SETUP =
ASYNBLK .
POWER - UP SETUP
When
834R01 is
in
place
,
the
set up
condit ions in
effect

ADDITIONAL CODE SETTINGS
834R01 enables an 834 to support Correspondence and Baudot codes . These select ions
appear in the set up m enu as CODE = CORRES and CODE
BAUDOT in
the
posit ions

834R01 also
provides
transfer
functions
that

ADDITIONAL IDLE SETTINGS
834R01 expands the IDLE m enu select ions to include IDLE = 2 and IDLE = ASYNCHR . These
select ions allow block asynchronous processing . ASYNCHR causes the 834 to treat each
character as an independent block . The IDLE = 2 set t ing causes the 834 to identify an idle
line after receiving no character for two " character t im es . " A character t im e is the lengt h of
t im e required to t ransm it or receive one character .

C
C
EXPANDED INSTRUCTION SET
834R01 provides sixteen program inst ructions in addition to those available with the 834 .
This allows expanded program abilit y in DTE and DCE sim ulati on m odes . Table 2-1 list s the
additional inst ructions available with 834R01 . These inst ructions are discussed in detail in

program the
834
to
send a
m essage in
a
triangular
pat t ern
to a print er ( or any DTE ) to verify that characters are posit ioned and print ed properly . The
program s produce the triangular pat t ern by sending a m essage in lines of increasing lengt h .
Each line is one
character
longer
than
the
preceeding line
unt il the
m essage is
print ed in full

After
the
transfer
function
is

steps as
they
are loaded and stops at m essage buffer 1. The m essage provided is 132 ASCII characters .
The user can send another m essage by changing the content s of the buffer .
In each program , the value of param et er 1 indicates how m any t im es the test is run . The
values of param et ers 2 and 3 determ ine how m any blank lines are inserted before and after
each print pat t ern . All param et ers are initially set to 1. Press START to begin execution .
