Operation
6.4 Operation
using
the "ILMVAC-Control"
The "ILMVAC-Control" PC program enables the vacuum controller to be operated simply and
easily from the PC.
The program is optionally available, together with the matching data cable, under
order number 620617
.
Connection options of the dual data cable VCZ 424
The dual-data cable must be properly connected to COM 1 or COM 2 of your PC so that the
"ILMVAC-Control" program automatically recognizes the vacuum controller.
The cable end marked P must be inserted into the RS 232 socket on the controller.
The end marked S must be inserted into the COM port of your PC.
First connect the cable, then switch on the controller. It should start perfectly normally, and
indicate the current pressure.
After "ILMVAC-Control" has been started, the Measure dialog is displayed with the pressure
curve diagram.
Instructions for the RS 232 connection and program start
If the cable is connected the wrong way round, the controller starts in software update mode
instead of in regular operating mode. In software update mode, the display goes out after an
initial beep. The controller software can now be updated via the dual data cable.
Mnemonic aid for connecting the cable: P end for programming mode on the PC.
