2.5.2 External bus connections
If a KF Titrino or a Coulometer which does not support automatic solvent
changing is connected to the 774 Oven Sample Processor then this can be
carried out with the help of a 700 Dosino. 685 Dosimats can also be used
for the addition of solvents. 700 Dosinos or 685 Dosimats are connected to
the 774 Oven Sample Processor via the so-called 'External Bus'.
A 729 Dosimat interface can be used to connect up to 4 dosing devices to
the 'External Bus' interface. Up to 3 Dosimat interfaces can be switched in
line (cascaded) and equipped with further dosing instruments. The instru-
ment address must always be set correctly at the interfaces. In this way it is
possible to operate up to 12 dosing instruments directly with the 774 Oven
Sample Processor with the aid of the DOS command.
