5.3.1 771 Compact Interface features
The Metrohm 771 Compact Interface is a two channel Analog-
to-Digital Converter to acquire two analog signals from two differ-
ent detectors simultaneously or time independent. It contains the
following parts:
• Two 24-bit Analog-to-Digital Converters (often abbreviated
as ADC) to acquire two analog signals from two different de-
tectors simultaneously (for example conductivity detection and
UV detection).
• • Two external start inputs.
The 771 Compact Interface is normally connected to a PC COM
port using the 6.2134.100 connecting cable. The 6.2128.170 ca-
ble is used to acquire the analog signal from the 732 IC Detector
(or another detector) and to start the data acquisition with contact
closure from the 733 IC Separation Center.
For detailed information about the 771 Compact Interface see
771 Instructions for Use.
