Installing
the
SPEX.SYS
device
driver:
To use the device driver, it must first be installed on the hard drive
of
your
DOS
computer. Refer
to
the GMI documentation for installation instructions. If you wish
to
move the SPEX Device Driver to another directory,
DOS
must be notified where the
driver can be found,
by
inserting
or
editing a line in the CONFIG.SYS file, which is
found in the root directory
of
the drive you use
to
load your operating system from.
The entry should look like one of these lines:
device= C:\SPEX.SYS
device=C:\SPEX.SYS
/0
device=C:\SPEX.SYS /1
device=C:\SPEX.SYS
/2
device=C:\SPEX.SYS
/3
0
device =
0
tells the operating system that we want
to
install a device driver.
"C:\SPEX.SYS" tells the operating system where the device driver can be found. If the
device driver is on the
D:
drive in a directory called \DRIVERS then the DEVICE
statement in CONFIG.SYS should be: •device=D:\DRIVERS\SPEX.SYS"
If no port parameter is given, the device driver will use the default (LPT1) printer port
to communicate
to
the monochromator.
0
/0"
tells the device driver
to
use the
LPT1
printer port.
0
/1
° tells the device driver
to
use the
LPT2
printer port.
•
/2"
tells the device driver
to
use the
LPT3
printer port.
•
/3"
tells the device driver
to
use the LPT 4 printer port.
NOTE: These optional parameters tell the device driver which port
to
use when
communicating with the Spex system. These numbers are actually index numbers into
a table
of
base addresses for printer ports that can be found in the BIOS memory area
of
the computer. The BIOS memory area begins at segment 0040 (hex). The location
of
the base address table can be found at offset 0008 (hex) within this segment.
Once the driver is installed and tested using the GMI software provided, you can begin
to
write code
to
control your 270M.
