SAD500 Serial Port Interface
The SAD500 S ERIAL P ORT I NTERFACE is a microprocessor-controlled A/D converter for serial port connection or
stand-alone operation. The SAD500 can be used to interface to desktop or portable PCs, PLCs, and other devices
that support the RS-232 communication protocol. The following are directions for setting up your SAD500.
Because A/D converter installation goes hand-in-hand with software installation, you will find directions for
installing OOIBase32 Spectrometer Operating Software included in this section as well.
Interface the SAD500 to your PC
Interfacing the SAD500 to a desktop or portable PC is simple.
1.
If you ordered your SAD500 mounted onto your spectrometer, simply connect the 6-pin DIN end of the serial
cable to the SAD500 and the DB9 end to your PC. If you ordered your SAD500 in its own housing, attach the
25-pin conductor ribbon cable from the spectrometer to the SAD500. Then connect the 6-pin DIN end of the
serial cable to the SAD500 and the DB9 end to your PC.
2. For either configuration, note the serial port number (also called COM Port ) on the PC to which you are
interfacing. (Older PCs may not have numbered ports.)
3. Plug the +12VDC wall transformer into an outlet and connect it to the SAD500.
Install OOIBase32
Before installing OOIBase32, make sure that no other applications are running.
1.
Execute Setup.exe.
2. At the “Welcome” dialog box, click Next>.
3. At the “Destination Location” dialog box, accept the default or choose Browse to pick a directory. Click Next>.
4. At the “Backup Replaced Files” dialog box, select either Yes or No. We recommend choosing Yes. If you
select Yes, you can choose Browse to pick a destination directory. Click Next>.
5. Select a Program Manager Group. Click Next>. At the “Start Installation” dialog box, click Next>.
6. Follow all prompts regarding the Spectrometer Configuration diskette that came with your system.
7. At the “Installation Complete” dialog box, choose Finish>.
8. When prompted to do so, restart your computer when the installation is complete.
Run OOIBase32
After you restart your computer, navigate to the OOIBase32 icon and select it. The first time you run OOIBase32
after installation, you must follow several prompts before you can begin taking measurements.
Operator and Serial Number Dialog Box
First, a prompt to enter a user name and serial number appears. Certain data files will include this information in
the header. (If, at a later date, you wish to change the operator name and serial number, select Edit | Settings from
the menu and then choose the Registration tab.) Click OK.
Default Spectrometer Configuration File
Next, the following message appears:
This appears to be the first time OOIBase32 has been executed. Please select a spectrometer
configuration file from the following screen. This spectrometer configuration file will be used each
time OOIBase32 is started.
A file open dialog box then appears. Navigate to the OOIBase32 directory, and choose the default spectrometer
configuration file -- the file with .spec as the extension, preceded by the serial number of your spectrometer. (A
default spectrometer configuration file will be named something similar to
I2J613.spec .)
