Interface parameters
The controller CVC 2000 II is equipped with a serial interface at the rear side of the housing (RS 232C, nine-
pole Sub-D-plug).
☞ Respectively plug-into or remove the cable (cable RS 232C, nine-pole Sub-D) from the interface only if
the equipment is switched off.
☞ The interface is not electrically isolated from the measuring circuit.
☞ For optimal electromagnetic compatibility assemble an interface filter (cat. no.: 638235).
The controller can be operated via serial interface. Measuring results, preselections and the status of the
controller can be read at any time. Controlling via interface is only possible, if the remote operation mode
has been preselected at the controller. During remote operation (”PC” is displayed) the controller can
be operated only via interface, the keys at the controller have no function, the warning triangle is
displayed.
