To print, the communication parameters (baud rate, data bits and
parity) of the instrument and the printer must match.
6.2.2 Connecting to a Personal Computer
Connect the colorimeter to a personal computer (PC) with the
computer interface cable (Cat. No. 48129-00) listed under
REPLACEMENT PARTS AND ACCESSORIES on page 57. The
cable provides a direct link between the colorimeter and the 9-pin
D connector used for the serial port on most personal computers.
If your computer has a 25-pin D connector, use a 9-pin to 25-pin
adapter (available at most computer supply stores).
Use a communications software, such as HachLink™ Software
(Cat. No. 49665-00) to collect data from the instrument.
HachLink is a Windows-based application that allows a personal
computer to capture data from several Hach instruments,
including the DR/800 Series Colorimeters.
The captured data can be stored in a text file as a spread-sheet
compatible format or as free-format text. Data captured in the
spreadsheet format is easily transferred into most spreadsheet
programs (i.e., Excel
®
, Microsoft Works
®
, Lotus 123
®
) for
graphing and reporting.
To install and run HachLink™ Software, the computer and
software must meet the following minimum requirements:
• PC with a 486/100 MHz or higher processor
• 32 MB RAM
• Hard drive with at least 20 MB free space
• 3½ inch floppy disk drive or CD-ROM drive
• VGA graphics with 640 x 480 or higher resolution,
256 colors
