2.4.1 External Bus Connections
Via the "External Bus" the 717 Sample Changer is operated by a
control instrument, e.g. the 726 Titroprocessor.
Four dosing instruments (Dosimat 685 or Dosino 700) may be
connected to the "External Bus" interface using a 729 Dosimat
Interface. Up to two Dosimat Interfaces may be connected in line
(daisy chaining) and be assembled with dosing instruments. Each
interface must be addressed correctly.
Before the instruments are connected, all devices have to be
switched off.
