6.4 Setting up the terminal software
Specific instructions are given in this manual for
communicating with personal computers running
under either the Windows 3.X or Windows 9X/NT operating
systems. Proceed to the appropriate section for detailed
set up procedures.
NOTE:
For computers operating under other operating systems,
contact the factory for assistance or consult the operating
system manual supplied with the computer.
6.4.1 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 up-loaded 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
6.4.2 Windows 9X/NT systems
Windows 9X/NT systems use a program called
hyperterminal to access the serial ports. To set up serial
communications with a personal computer running under
Windows 95, Windows 98 or Windows NT, make sure the
GF868 is powered on and complete the following steps:
1. From the Windows START menu, select
PROGRAMS>ACCESSORIES>HYPERTERMINAL>HYPERTERMINAL.
2. The NEW CONNECTION window should appear (if it does
not, select it from the FILE menu). After entering the
desired CONNECTION NAME and selecting an ICON, click
on OK.
3. When the CONNECT TO window appears, select the serial
communications port (COM1 or COM2) to which the
GF868 is connected and click on OK.
4. When the COMx PROPERTIES window appears, make sure
the settings are as follows:
• Bits per second: 9600 (must match the GF868 setting)
• Data bits: 8
• Parity: none
• Stop bits: 1
• Flow control: Xon/Xoff
After making any necessary changes, click on OK.
5. Open the TRANSFER menu and select CAPTURE TEXT. Enter
the desired DRIVE:\DIRECTORY\FILENAME for the file about
to be transmitted, and 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. When the transfer has been completed, open
the TRANSFER menu and select CAPTURE TEXT>STOP. The
uploaded file may now 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.
