2.4 Connection of external instruments
2.4.1 General information
Before an external instrument is connected to the 762 IC Interface, the
762 IC Interface must always be switched off using mains switch 11 !
Each system of the two versions of the 762 IC Interface has four RS232
interfaces 14 14 or 18 18 for connection of a maximum of 8 external instru-
ments, an 11 11 or 15 15 interface for analog signals from a maximum of 2
detectors and 8 remote output lines 12 12/13 13 or 16 16/17 17 for controlling ex-
ternal instruments by making contacts or impulses (see Fig. 2 and
Fig. 4). Information about the technical data of these interfaces is given
in section 4.1.
For installation and startup of external instruments proceed as follows:
1 Switch off all instruments
• Switch off 762 IC Interface and all external instruments using
the mains switch.
2 Connect instruments
• Connect the instruments to the 762 IC Interface according to
the connection diagrams shown in sections 2.4.2 to 2.4.9 by
using the cables named in the diagrams. Other instrument
combinations can be set up by using these examples as a
guide .
3 Switch on all instruments
• Switch on 762 IC Interface and all external instruments using
the mains switch.
4 Instrument settings
Operation with the 762 IC Interface requires that the following
settings must be made:
• 732 IC Detector:
>CONFIG/RS settings
handshake: SWchar
>CONFIG/RS settings
RS control: on
• 709 IC Pump:
Switch on external control of the 709 IC Pump using the
[ EXT. ] key.
• 752 Pump Unit, 753 Suppressor Module,
754 Dialysis Unit:
Switch on external control via remote interface using the
[ Remote ] switch.
