I have a question about a bipolar signal issue i have with one of my machine at work. Been rattling my brain for awhile on this.
The Machine i am working is a customers machine and i am not allowed to even open the machine taking this in consideration before i start.
The Signal is comming out of a 15db pin connector with a -16v from each pin. the port does not have a postive pin or a gnd pin, just the -16v used for presence. the chasis is the postive signal. i do realize i need a +16v to complete the cirsuit, but i dont have cuase i am not allowed to tap into the machine powersupply. sounds complicated but i am stuck on this part.
i am trying to connect the arduino to every pin to keep a log and count of everytime the there is signal (presence) when a part is detected.
Can anyone here give me some kind of advice? It would be nice if i do get positive repsonds.
would really appreciate and many thanks in advance.
