Hence, a 7 will be interpreted as : Initialize mono drive, shutters, slits, and internal
variables.
SYNTAX:

EXAMPLES:
"I

- initialize table and set delay counter used for communication with hardware.
"I
9 38000;" -Ā·initialize monochromator only. Do not initialize table
or
set delay counter.
"I
10;" - initialize shutters only. Do not initialize table
or
set delay counter.
"I
12 1120;" - initialize slits only. Do not initialize table
or
set delay counter.
"I
7 34000 1120;" - FLAGS is given the value of 7

+2+4).
Therefore the
monochromator, shutters, slits, and internal variables are all initialized (i.e. total
system initialization). Because the monochromator is being initialized, the calibration
position is supplied (34000) and because the slits are being initialized, the maximum
slit width is supplied ( 1120).
"I
4 1120;" - FLAGS is given the value
of
4
Q.e.
initialize slits and initialize internal
variables). The maximum slit width is supplied (1120).
Whether the system is initialized partially
or
not, the FIRST (and possibly the only)
initialization command should set the internal variables and the counter that is used
for communication delays.
To
the user of this protocol, this means that the first
initialization string can not consist
of
a
FLAG
parameter with a value greater than
seven (so that the internal variables are set). It also means that
if
there is more than
one initialization command sent
to
the device driver, the commands other than the
first should have a FLAG parameter with a value of at least eight (so that the internal
