2.3.6 Connecting a computer
The report output via the RS232 interface can be made to either a print-
er or a PC. With the program Metrodata Vesuv 3.0 for Windows it is
possible to implement automatic data acquisition and evaluation.
This is done by connecting RS232 interface 10 of the pH/Ion Meter us-
ing the optionally available 6.2134.040 Cable (9-pin/9-pin) with a free
serial COM port on the PC. If only a 25-pin COM port is available then
the optionally available 6.2125.110 Cable (9-pin/25-pin) or a commer-
cially available adapter must be used.
Settings
The RS232 interface must be configured with identical settings on both
the connected instruments (PC and pH/Ion Meter). You should select
the standard values for the pH/Ion Meter configuration under CON-
FIG/RS232 settings (see Section 5.7):
Baud Rate: 9600
Data Bit: 8
Stop Bit: 1
Parity: none
Handshake: HWs
Please note that, before starting the program 'Vesuv Datalogger', the
pH/Ion Meter must have been configured correctly, connected up and
switched on. When the Vesuv program is started it automatically
checks the configuration of the connected instrument and makes the
corresponding settings for the report output so that data acquisition
functions properly.
As well as the data acquisition function described above, the 780/781
pH/Ion Meter also has numerous remote control possibilities that allow
the complete control of the instrument via the RS232 interface. Howev-
er, as the utilization of this option only makes sense in very special situ-
ations, you can obtain detailed information about the remote control
language of the pH/Ion Meter from your local Metrohm agency in a
separate document (780/781 pH/Ion Meter Operation via RS232;
8.781.1113).
