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.
