Address Selection; Using The 1061/1071 In A System; Programming Instructions - Datron 1061A User Handbook Manual

Address
selection
The
instrument address
is
set
manually
using a
six
way
miniature
switch near
the interface
connector
on
the rear panel. Five of the switches
are used to
set
the address,
and
using a binary
code,
this
enables
any
address
in
the
range 00
to 30
to
be used,
e.g.
1
1010
is
address
26.

Talker
only'
('T.O.')
The
sixth
switch,
when
set
to a'T", causes the
DVM
to
become
a
'talker only',
meaning
it
can only output
data
and not
be
programmed
over
the interface.
This
is
particularly useful
if,
for
example,
the
system
consists
of only a
DVM
(the talker)
and
a printer
(the listener), in
which
case
a
controller
is
not
required.

Address
31
(Illegal
bus
address)
If
the interface option
is
fitted,
the address selected
affects the
manner
in
which
the
DVM
powers
up.
With
address
31 selected, the
DVM
assumes
the
role
of
bench instrument and powers up
to
DC,
1000V
range
and
reading
at
the
internally controlled
read
rate.
In addition, a
manual
calibration
is
only
enabled with
Address
31 selected, as
explained
in
the
Calibration
and
Servicing
Handbook.
With an address
selected in
the range 0
to
30,
the
instrument
powers
up
as a systems instrument
in
DC,
1000V
range butin'Hold'.
Each
time power-up
occurs
in
this
condition, a message
is
sent
to
the
system
controller to indicate that
an instrument
power-up
has taken
place.
Using the 1061/1071
in
a
system
The
DVM
can be operated under remote
control,
when ASCII
coded
programming
instructions are
received
from
a controller,
or
in local
control
when
the
DVM
is
operated
from
its
front/ rear controls.
In
both cases output of
results
or parameters
is
available at
both
DVM
display
and
via the interface.
When
operating
in
remote
the legend 'rem'
is
displayed
and
all
front
panel
controls are disabled
except 'Power',
4
2/4-wireH
',
'Local/
Remote
Guard'
and
in certain trigger
modes
'Man'.
