Computer
The 2020ppbPRO will download information stored in its datalogger to a Windows
®
based computer. This option may be used if you need to prepare reports based on
the 2020ppbPRO
’s recorded data. This feature may also be used if you need the
recorded data in a format that can be imported into a spreadsheet or database for
further calculations.
NOTE: The 2020ppbPRO is not classified for use in hazardous locations when connected to
any computer.
The instructions below will provide you with the basic information for using the
2020ppbPRO with the 2020ppbPRO communications software, the 2020ppbPRO
Comm. In order to use these instructions, you must be familiar with Microsoft
Windows and it must be installed and running on your computer.
To initiate communications between the 2020ppbPRO and a PC:
1. Turn the 2020ppbPRO off.
NOTE: You must turn the instrument off before connecting or disconnecting the computer
cable.
2. The 2020ppbPRO must be connected to a serial port. Use the computer
cable (Part No. MX750120) to connect the 2020ppbPRO to one of the
computer’s serial ports. Remember which serial port you are using as you
will need this information when you set up the 2020ppbPRO
Communications software. Normally you will use Com1 or Com2.
3. If the 2020ppbPROprinter cable plugs directly into the port on the computer
without the gender changer or the 9 to 25-pin adapter, you are most
probably connected to a parallel port. You will need at least one of the
adapter cables to connect the 2020ppbPRO to a serial port. Once all
connections have been made, turn on the 2020ppbPRO instrument.
4. Start the 2020ppbPRO Comm software as you would any Windows
®
program. The 2020ppbPRO Comm splash screen will appear on the PC.
Once the 2020ppbPRO Comm software is running, the PC is ready to
receive data from the 2020ppbPRO.
5. On the 2020ppbPRO, the number of data bits has been fixed at 8, stop bits
has been fixed at 1. Parity has been set at None and the Flow control is
Xon/Xoff. These values are set automatically by the 2020ppbPRO Comm
software.
6. On the 2020ppbPRO , press the MENU key, choose “Data Log Options”,
then press the SELECT key.
7. Choose the “Download to PC” option using the DOWN ARROW key and
press the SELECT key.
8. Follow the 2020ppbPRO prompts to start the data download.
NOTE: A DB-25, female connector is sometimes a parallel port. Do not connect the serial
port of the converter to a parallel port.
