SECTION 5 PRINTING AND DATA TRANSFER
5.1 Connecting to Printers/Computers
5.1.1 Connection with the RS232 Cable
The standard 9-pin RS232 connector on the Docking station
connects with a 9-pin sub-D connector. A suitable cable is listed
under
REPLACEMENT PARTS on page 79 .
The RS232 interface output is an 8-bit data word plus one stop bit
and no parity with a baud rate of 1200. It can communicate with a
serial printer or a serial port on a computer.
5.1.2 Connecting to a Printer
Connecting a serial printer to the Docking Station requires a 9-pin
to 25-pin RS232 cable. The cable provides a direct link between
the instrument and the 25-pin connector used for the serial port on
most serial printers.
Table 3 shows the proper pin connections for
25-pin printer cables. Using cables that do not match the pin
information in the table may cause undesirable operation.
Parallel printers require a serial-to-parallel adapter. This allows
use of printers that are normally used for IBM-compatible
applications.
The Citizen PN60 printer requires a special printer cable that is
shipped with the printer when it is ordered from Hach Company.
