7.4 Measured value enquiry via web browser/
RS232
Measured value enquiry via RS232 interface and PPP (Point to Point
Protocol) is used if no internal company network or other direct con-
nection is available. PPP is a transmission standard for serial connec-
tion between two computers (points). A dial-up line (telephone line)
with a modem is usually used for this.
Measured value enquiry by means of web browser is a dial-in connec-
tion. The signal conditioning instrument accepts an incoming call and
reacts to the calling host like an Internet Service Provider (ISP). This
allows data exchange with the signal conditioning instrument via http.
The dial-up connection makes it possible to access the HTML pages
of the signal conditioning instrument with a web browser.
If a telephone connection is not available, a GSM wireless modem
with RS232 interface can also be used. In this case, a GSM mobile
phone contract with the option of data transmission is required. Make
sure that your location is sufficiently covered by the network of the
mobile network operator. In addition, the PIN of the SIM card used
must be deactivated.
