Communicating with SITRANS F 1010 Systems via the RS-232 Interface
The following sections assume that you are familiar with the basics of using Windows
95/98/NT/2000/XP based communications program. Most computers provide at least one
serial port using either a 9-pin or 25-pin D-type connector. The port designation can be either
COM 1 or COM 2. Usually, when a computer includes two serial ports, COM 1 will be the 9-
pin connector and COM 2 will be the 25-pin connector. However, port designations can vary
from manufacturer to manufacturer, so you will have to positively identify the COM port you
wish to use for the meter interface. Connect the cable between the meter and your PC using
the 25-pin, 9-pin or USB to RS-232 adapter connector, depending upon the port’s
architecture.
How to use the Windows HyperTerminal Program
Note
Si-Ware
If you want to use the Si-Ware program instead of HyperTerminal, download the program at
[http://s13.me/ns/cv] and follow the setup instructions.
Windows provides a communication program called HyperTerminal, which is ideal for
interfacing your computer with the meter. The following typical example explains how to set
up HyperTerminal.
Note
Depending upon the Windows applications being used this setup procedure may vary.
1. Invoke HyperTerminal.
2. Set Com port to port that is designated for use (COM 1).
3. Confirm port settings match the RS-232 setting in the meter.
