Hardware addressing The hardware addressing is effective if an address <126 is set with the address selection switches on the electronics module of VEGAFLEX 83. Software addressing thus has no effect - only the set hardware address applies. Software addressing The software addressing is only effective if address 126 or higher is adjusted on the instrument with the address selection switches.
