iÃ‚Â´ve got an multimeter (voltcraft vc820) connected to my serial port , and i want to get the data into v4.
i used a rs232 node, which works fine, but the problem is (outlined here):
the data is encoded in hex, so i need to covert it to numerical values and strip the unneeded data (betriebsmodus, etc)…
but iÃ‚Â´ve got no idea how to do the “umrechnung” in v4…
maybe one of you elektrotechnik-wizards can give me a hint?
