To print, the communication parameters (baud rate, data bits and parity) of
the DR/2010 Spectrophotometer and the printer must match. The
instrument default settings for printing are baud = 9600; parity = none; bits
=8.See3.2.1 Using the Setup Menu, to select other Serial
I/O settings.
Default settings of the instrument match the default settings on the Citizen
PN 60 Printer with the exception of the serial interface (serial I/O)
protocol setting. Change the protocol setting from XON/XOFF to DTR in
the Citizen Printer setup menu (see the printer manual for instructions).
The tabular format of the DR/2010 Spectrophotometer is compatible with
serial printers that are at least 80 characters wide. Graphics can only be
printed in printers that are directly compatible with an Epson LQ-570+ or
Citizen PN-60 printer. See 3.7 Printing Data for more details.
2.8.2 Connecting to a PC
The DR/2010 Spectrophotometer requires a special cable (Cat. No.
48129-00) to connect the instrument to a personal computer (see Optional
Accessories in REPLACEMENT PARTS on page 99.) The cable provides
a direct link between the DR/2010 Spectrophotometer 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). See Table 2 and Table 3 if you
need to wire a cable for special applications.
The PC must have software that can accept the data from the DR/2010
Spectrophotometer (i.e., Windows
™ Terminal, HachLink™...).
The communication parameters (baud rate, data bits and parity) of the
DR/2010 Spectrophotometer and the computer must match.
See section 3.2.1 Using the Setup Menu, to select the Serial
I/O settings.
