PRINTING AND DATA TRANSFER
The standard 9-pin RS232 connector on the meter connects with a
9-pin sub-D connector. Hach offers an RS232 9-pin to 5-pin cable
(Cat. No. 48129-00).
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.
Connecting a serial printer to the meter requires a 9-pin to 25-pin
RS232 cable (Cat. No. 49503-00). 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.
