SECTION 5 PRINTING/TRANSFERRING DATA
5.1 Connecting To Printers/Computers
5.1.1 Connecting With The RS232 Cable
The standard 9-pin RS232 connector on the meter connects with a
9-pin D-sub connector. A suitable cable is listed under Optional
Apparatus in Replacement Parts.
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 meter 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 4 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 cable to fit into the
printer. This cable is shipped with the printer when ordered from
Hach Company.
