The 2020ComboPRO 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 2020ComboPRO’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 2020ComboPRO 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

2020ComboPRO with the 2020ComboPRO communications software, the

2020ComboPRO ProComm. 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 2020ComboPRO and a PC:

1. Turn off the 2020ComboPRO.

NOTE: You must turn off the instrument before connecting or disconnecting the computer

cable.

2. The 2020ComboPRO must be connected to a serial port. Use the computer

cable (Part No. MX750120) to connect the 2020ComboPRO 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 2020ComboPRO

Communications software. Normally you will use Com1 or Com2.

3. If the 2020ComboPRO printer 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 2020ComboPRO to a serial port. Once all

connections have been made, turn on the 2020ComboPRO instrument.

4. Start the 2020ComboPRO ProComm software as you would any Windows

program. The 2020ComboPRO ProComm splash screen will appear on the

PC. Once the 2020ComboPRO ProComm software is running, the PC is

ready to receive data from the 2020ComboPRO.

5. On the 2020ComboPRO, 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 2020ComboPRO

ProComm software.

6. On the 2020ComboPRO, 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 2020ComboPRO prompts to start the data download.
