6-4 Serial Communications
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 GS868 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 GS868 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 GS868 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 GS868, 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.
