Serial Communications 6-3
12/1/99
Windows 3.X Systems To set up serial communications with a personal computer running
under Windows 3.X, make sure the GF868 is powered on and
complete the following steps:
1. In Windows 3.X, select the Terminal Function, which is usually
located in the Accessories window.
2. The Terminal Screen appears, with six menus located at the top of
the screen. Using the Settings Menu, select the Communications
option.
3. When the Communications Screen appears, make the following
selections:
• Baud Rate - set to the same value as the GF868 setting
• Data Bits - 8
• Stop Bits - 1
• Parity - None
• Flow Control - Xon/Xoff
• Connector - select the correct communications port
• Parity Check - not checked
• Carrier Detect - not checked
4. Using the Transfer Menu, select the Receive Text File option.
5. A window appears asking for a file name. Select the desired
directory and file name (with .prt extension) and then click on OK.
6. From the keypad on the GF868, enter the
PRINT menu and select
the log file to be uploaded to the computer in numeric format. See
Chapter 4, Printing Data, for detailed instructions on this
procedure.
7. The logged data will begin appearing on the computer screen.
After the transfer has been completed, the uploaded file may be
used in any software program, just like any other text file.
Note: If the RS232 link does not function, switching the leads to pins
2 (TX) and 3 (RX) at the RS232 connector on the meter often
solves the problem.
