cable provides a direct link between the meter 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).

Table 4 shows the proper pin connections for 9-pin computer
cables. Using cables that do not match the pin information in the
table may cause undesirable operation.
1. Connect the RS232 cable to the Docking Station by lining up
the holes in the cable connector with the pins of the
serial port.
2. Gently and firmly push the cable into the Docking Station.
3. Secure the connection by tightening the screws on either side
of the cable connector (see Figure 8). Connect the cable to
the printer in the same manner.
4. Once the communication link is established, press
send data to the computer.
To transfer data, the communication parameters (baud rate, data
bits and parity) of the meter and the computer must match. Once
the communication link is established, press
the computer.
Use a communications software, such as HachLink™
(Cat. No. 49665-00) to collect data from the instrument.
