Connection to 762 with «IC Net»
When a modular IC system consisting of 732 IC Detector, 733 IC
Separation Center, 709 IC Pump, and 762 IC Interface is operated with
the PC software «IC Net» as "Master" the 750 Autosampler sample
change procedure will be started by a signal from the 733 IC Separa-
tion Center. The Autosampler must be connected to the 762 IC Inter-
face using the 6.2134.000 cable and to the 733 IC Separation Center
using the 6.2128.100 as shown in Fig. 7.

the RS232 interfaces 14
14 or 18
18 at the 762 IC Interface using
the 6.2134.000 cable.
2 Electrical connection 750 – 733
