•
Signal conditioning instrument with RS232 interface
•
PACTware with suitable device DTM
•
Modem with RS232 interface
•
Telephone connection at the location of the signal conditioning
instrument (not necessary with GSM modem)
•
Windows PC with modem, telephone connection and web browser
(e.g. Internet Explorer)
Connect the signal conditioning instrument to the PC with PACTware
via the RS232 interface (see chapter "Connection"). After the configu-
ration, you can connect the modem instead of the PC. If changes are
necessary later, you can access the instrument remotely via modem
and carry out your settings.
Configuration of the RS232 interface of the signal conditioning
instrument
Start PACTware with the suitable DTM and carry out the following
configuration.
With this setting, you define which mode the RS232 interface should
operate in. The following options are available:
•
VVO protocol: Direct serial connection between signal condition-
ing instrument and PC for parameter adjustment and enquiry (e.g.
with PACTware and DTM)
•
PPP: Dial-up connection between signal conditioning instrument
and modem for independent transmission of e-mails (dial-out con-
nection) or enquiry via web browser (dial-in connection)
•
ASCII protocol: Direct serial connection between signal condi-
tioning instrument and PC for enquiry with terminal programs, e.g.
Hyperterminal
1. Select the option "PPP" for connection of a modem for measured
value enquiry via web browser.
When connecting a modem, you should switch on this option so that it
will be provided with parameters necessary for data transmission.
The Point to Point Protocol (PPP) enables the transmission of LAN
protocols (e.g. http) via point-to-point connection. PPP connections
are e.g.:
•
Switched connections via the analogue telephone network with
analogue, ISDN and GSM modem
•
Standard connections
2. When connecting a modem for measured value enquiry via
web browser, select under "Dialing direction" the option "Dial-in
(incoming connections)".
3. Select in the navigation section "Dial-in" and enter the following
data under "Settings for ISP emulation":
4. Enter here an individual user name for your connection. This
name must be used later on for the dial-up connection.
