Connecting to a Personal Computer
Connect the Docking Station to a personal computer (PC) with
the computer interface cable (Cat. No. 48129-00) listed under
REPLACEMENT PARTS AND ACCESSORIES on page 85. The
cable directly links 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 15 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. Align the holes in the RS232 cable connector with the pins in
the serial port of the Docking Station.
2. Gently and firmly push the cable into the Docking Station.
3. Tighten the screws on each side of the cable connector
(see Figure 9). Connect the cable to the computer in the
same manner.
4. Once the communication link is established, press
to
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
to send data to
the computer.
