2A-1. Programming
instructions (con!)
Ail command
string characters
transmitted
via the remote
interface must
be
ASCII
7-bit upper
case characters.
A
command string is
a sequence of 1 to
31 characters.
(For the 8505A and
8506A, a command
string may have
up to
59
characters.)
Characters are
classified
as immediate,
command or termination. The instrument
may be placed in
Remote mode by transmitting
any character
that the instrument
will recognize from
the remote controlling
terminal.
#
With the IEEE Interface
installed,
the REMOTE
switch can only
be used to select
local mode if
already in
Remote.
REMOTE
is the
only front panel switch
to remain
active when in REMOTE
mode; REMOTE
may, however,
be
locked out
by
the
local lockout
command.
IMMEDIATE
CHARACTERS
There are
5 immediate
characters;
each of these
may be
executed at any
time and
does not require
a
termination
character.
f

“s
^
Reset
This immediate
character will
reset the instrument
to
the conditions
described under INITIALIZATION.
$
When transmitted,
the reset
character must not
be
followed
by any other
character for
3 seconds with
the
8502A
(2
seconds
with the 8500A).
Any carriage return
or line feed following
the reset
character must
be
suppressed. The remote
interface
will be unable
to
accept programming
characters
during this time.
r~
"\
%
Hail
V__U
The halt
character is
used to terminate
the continuous
mode and
cause the instrument
to
wait for a command
string. No
other characters
should
precede the halt
character if
continuous mode
is in effect.
Upon receipt
of the halt character, the
transmission
of readings
is
terminated
immediately.
The following
trigger
mode
transitions
will occur when
halt is
used:
From: Continuous
Line
Synchronous
To:
Single Reading

v
$
This character
will command
the instrument
(Options-
06 or
-07
only) to enter local
mode of operation
and lock
out the remote
interface.
$
The Remote
mode
may then
be reentered
by pressing
the front
panel REMOTE
switch
(for Option
-06,
-07).
The Remote
mode
may not be reentered
from
the front
panel when
using the IEEE-488
Interface
(Option -05).
