1.1 Instrument description
762 IC Interface 1
1 Introduction
1.1 Instrument description
The 762 IC Interface provides the connection between the PC and
external IC or HPLC peripheral instruments. Up to 16 instruments in-
cluding 4 detectors can be connected to the 762 IC Interface and con-
trolled either uniformly or independently by means of the «IC Net»PC
software. The IC 762 Interface can also record and convert the analog
signals from a maximum of 4 channels (two at once) which are proc-
essed at very high resolution.
Fig. 1 shows an overview of all the Metrohm instruments which can be
connected to the 762 IC Interface and are described in these
‘Instructions for Use’. It is also possible to connect Bischoff instru-
ments; please refer to the «IC Net»on-line program help as well as the
relevant Bischoff instruction manuals.

1 Introduction
762 IC Interface8
1.4 Safety notes
While electrical safety in the handling of the 762 IC Interface is assured
in the context of the specifications IEC 1010-1 (protection class 1, de-
gree of protection IP40), the following points should be noted:
• Mains connection
The mains connection must be effected in accordance with the
instructions in section 2.2.
• Opening the instrument
Inside the instrument there are no parts which must be set or adjusted
by the user.
If the 762 IC Interface is connected to the power supply, the instru-
ment must not be opened nor must parts be removed from it, other-
wise there is a danger of coming into contact with components which
are live. Hence, always disconnect the instrument from all voltage
sources before you open it and ensure that the mains cable is
disconnected from mains connection 88 !
• Protection against static charges
Electronic components are sensitive to static charging and can be
destroyed by discharges. Before you touch any of the components
inside the 762 IC Interface, you should earth yourself and any tools
you are using by touching an earthed object (e.g. housing of the
instrument or a radiator) to eliminate any static charges which exist.

2.1 Setting up the instrument
762 IC Interface 9
2 Installation
2.1 Setting up the instrument
2.1.1 Packaging
The 762 IC Interface is supplied together with the separately packed
accessories in special packagings containing shock-absorbing foam
linings designed to provide excellent protection. The instrument itself is
packed in an evacuated polyethylene bag to prevent the ingress of
dust. Please store all these special packagings as only they assure
transport of the instrument free from damage.
2.1.2 Check
After receipt, immediately check whether the shipment is complete and
has arrived without damage (compare with delivery note and list of
accessories in section 4.2). In the case of transport damage, see
instructions in section 4.4.1 "Warranty".
2.1.3 Location
Position the instrument in the laboratory at a location convenient for op-
eration, free from vibrations and protected against a corrosive atmos-
phere and contamination by chemicals.
2.1.4 Arrangement of the instruments
The 762 IC Interface can be piled up together with other IC instruments
(e.g. 732, 733, 709).

2 Installation
762 IC Interface10
2.2 Mains connection
2.2.1 Mains voltage and fuses
The 762 Interface has a power supply which automatically adjusts itself
to the existing mains voltage (100…240 V) and frequency (50…60 Hz).
It is equipped with an electronic overload protection device and also
has two fuses; however, these should only be exchanged by Metrohm
service technicians.
2.2.2 Mains cable
The instrument is supplied with one of three mains cables
• 6.2122.020 with plug SEV 12 (Switzerland, …)
• 6.2122.040 with plug CEE(7), VII (Germany, …)
• 6.2133.070 with plug NEMA 5-15 (USA, …)
which are three-cored and fitted with a plug with an earthing pin. If a
different plug has to be fitted, the yellow/green lead (IEC standard)
must be connected to the earthing socket 77 (protection class 1).
Any break in the earthing inside or outside the instrument can make it
a hazard!
Plug the mains cable into mains connection plug 88 at the 762 IC Inter-
face (see Fig. 3 and Fig. 5).
2.2.3 Switching the instrument on/off
The 762 IC Interface is switched on and off using mains switch 11 (see
Fig. 2 and Fig. 4). When the instrument is switched on the mains pilot
lamp 22 lights up.

2.3 Connection to the PC
762 IC Interface 11
2.3 Connection to the PC
2.3.1 Connecting cable
Always switch off 762 IC Interface and PC before you connect the two
instruments with the 6.2134.100 Cable.
Connect the PC connection 1010 at the 762 IC Interface to one of the se-
rial COM ports at the PC using the 6.2134.100 Cable (9 pin/9 pin). If
only a 25-pin COM interface is available on the PC then the 6.2125.110
Adapter cable or a commercially available adapter must be used.

2.3.2 Software installation
The PC program «IC Net 2.0» is required for the operation of the 762
IC Interface; this is contained on the 6.6034.003 CD included in the ac-
cessories. This program runs under Windows 95, Windows 98 and
Windows NT operating systems and is installed according to section
1.4.2 of the «IC Net»Instructions for Use.

2 Installation
762 IC Interface12
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 1414 or 1818 for connection of a maximum of 8 external instru-
ments, an 1111 or 1515 interface for analog signals from a maximum of 2
detectors and 8 remote output lines 1212/1313 or 1616/1717 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:
1Switch off all instruments
• Switch off 762 IC Interface and all external instruments using
the mains switch.
2Connect 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.
3Switch on all instruments
• Switch on 762 IC Interface and all external instruments using
the mains switch.
4Instrument 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.

2.4 Connection of external instruments
762 IC Interface 13
• 750 Autosampler:
Always switch on the 762 IC Interface first and then the 750
Autosampler.
• 766 IC Sample Processor:
