Please read the information about the use of data cards given on page 5
and consult the documentation accompanying the card.
11.4 File backup
It is a good idea to backup method or determination files regularly on a
personal computer. The files can be transmitted to the PC via an RS232
interface. They can be stored on the hard disk or on a floppy disk.
The 'Metrodata 796 PC backup'-software (6.6026.010) is required for this,
together with a serial 6.2125.060 cable to connect the Titroprocessor with
the PC. A PC terminal program can be used as an alternative; this must
support the Kermit transfer protocol. For setting the data transmission
protocol see page 36.
Interface configuration for data backup:
• Connect the serial cable to RS232 socket 1 or 2 of the Titroprocessor
and to the
COM1 or COM 2 connection of the PC.
• Under [Config.][Interfaces] set the communication mode of the
corresponding RS232 interface to ‘LIMS’.
• The transmission parameters of the corresponding RS232 interface must
be set as follows:
Baud Rate 9600
Data Bit 8
Stop Bit 1
Parity none
Handshake Hweinf
For transmitting files switch data reception to 'off', for receiving them
switch it to 'on'.
The settings of the backup software must agree with the settings of the
Titroprocessor interface.
