6.1.3 Connecting to a Personal Computer

Connect the meter to a personal computer (PC) with the computer
interface cable (Cat. No. 48129-00) listed under REPLACEMENT
PARTS on page 77. The 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 meter by lining up the holes
in the cable connector with the pins of the serial port.
2. Connect the cable to the computer in the same manner (see
Figure 7).
3. 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.
