3. Configuration
726 Titroprocessor, Instructions for use 45 45
The settings:
Communication
Int.
RS232 interface for the connection to a PC
Commun. mode
Data transmission mode:
keyCTRL
Remote control of Titroprocessor by key-
code simulation, see page 273f.
keySEND
Transmit key-codes . The Titroprocessor
sends the codes of the keys pressed via
the RS232 interface.
LIMS
Data output to a PC or a LIMS system,
e.g. for raw data reports to the database
software Metrodata VESUV 3.
off
No data transmission
3.3.4 Internal thermal printer
These settings are only available on Titroprocessor models 2.726.0020 and
2.726.0120.
The built-in printer can be used as well as an external printer connected to
an RS232 interface.
Internal printer
Switches the internal printer on/off. A printout of the
screen contents with the key is
still possible with the 'off' setting.
Enable
auto FF 'off'
allows the use of the automatic page feed in
report definitions. If Metrohm thermal paper (Order
no. 6.2237.040) is used the perforation is
automatically skipped during printout.
3.3.5 Initializing the RS232 interfaces
If problems occur during data transmission or data reception via the RS232
interfaces it may be necessary to initialize the affected interface again. This
can be carried out by pressing the softkeys [Reset RS232 1] or
[Reset RS232 2]
.
During initialization of an RS232 interface the reception buffer and the output
buffer of the RS232 interface are cleared and the transmission parameters
newly set.
The Titroprocessor 726 interfaces are set to a time out period (time out) of
30 seconds, i.e. if data are to be transmitted to an external instrument then a
connection must be made to this instrument within 30 seconds, otherwise a
connection problem is assumed and a corresponding error message
displayed.
If this occurs with a printer then first check whether it has been correctly
connected and is switched 'online'.
