Rapid Scanning Imaging Spectrograph

Software
Installation
and
Control
Interfacing:
The 270M must be controlled by an external controller
or
computer. The full
automation
of
all moving parts
of
the spectrometer makes it unnecessary
to
have
direct physical access
to
the· instrument.
If
your
270M does
not
contain the optional SPEX232
or
SPEX488 interface, the
Graphical Monochromator Interface (GMI) software is provided. Along with the GMI,
there is a software driver, SPEX.SYS, that contains the low level code that the GMI
is
built on. SPEX.SYS is described in a following subsection.
Spex also offers several software options
to
control your 270M, such as AutoScan for
use via a DataScan controller, QuikView for use in conjunction with a QuikScan
Photodiode Array, and the DM3000 Spectroscopy Computer. Each
of
these are
configured at the :factory for your system and you need not be concerned with
protocols
or
handshaking.
· A Programmer's Instruction set is also provided with systems that include the optional
DataScan controller,
or
the SPEX232
or
SPEX488 interfaces.
Each group
of
controlling options is outlined in this section, along with direction
to
further documentation, if necessary.
Refer
to
the Electrical Connections section for appropriate cable connections.
At this point, the installation procedure branches. Please find the subsection pertaining
to
the software/ controller you will be using.
4.1
Standard Graphical Monochromator Interface Software (GMI):
If
your
270M does
not
contain the optional SPEX232
or
SPEX488 interface, the GMI
software is provided
on
a diskette for installation on a PC running MS DOS 3.3
or
5.0.
You will need
to
know the number
of
an available parallel port
(LPT1
,2,3,~r 4) .
. Connect the 35816 cable
to
that port, and
to
the 270M standard spectrometer 1/0
connector.
To
Install the GMI software on your PC:
■
Boot
your
PC
■
Insert the diskette into the floppy drive and from the DOS prompt, type"A:
