External I/O
Connections between Micro GCs and external devices are made with the appropriate cable to the
External I/O port. The external I/O port can handle six analog inputs (input 0 to 10 Volt).
The user interface receives analog information and translates it into actions to be taken by the
local user interface, events, or data to be shown or stored in the remote user interface. In OpenLAB
EZChrom and OpenLAB ChemStation only status is visible.
