Interface parameters
The CVC 3000 controller is equipped with a serial interface (RS 232C,
nine-pin Sub-D-plug).
+
Plug-in or remove the cable (cable RS 232C) 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 is fully operable via the serial interface. Measuring results,
preselections and the status of the controller can be read at any time.
The factory-set read and write commands are completely compatible
with the VACUUBRAND CVC 2000 controller (see sections ”Read / Write
commands CVC 2000”). An extended instruction set is available using the
command ”CVC 3” (see sections ”Read / Write commands CVC 3000”).
Setting of the interface
Set the interface parameters directly at the CVC 3000 controller. The fac-
tory set values are underlined.
Edit and confirm the interface parameters in the ”Configuration” menu in
”RS-232” submenu using the selection knob.
