Re: DR512 Drums

Any news on the adapter tool?

Re: DR512 Drums

Where can you find this adapter tool?

Looks pretty do-it-yourself. Guess you have to connect it somewhere and the resistors causing a fake-new-drum message triggered with the dip switch. Would be great to get in touch with a wiring diagram or what did it cost you?^^

Re: DR512 Drums

One wire is common one is a just a bridge to let the machine know the drum is there and one is an ICP that pops to reset the count.
The timing for the C360 is easy its about a second after the front door closes. They changed that on the C364 machine to make it a bit more tricky.

I just checked new chips - resistor value for K is ~33k and color (yellow) is ~5k - can't be hard to figure this out

yeah but that PCB doesn't look much intelligent so if the timing is tricky I guess you have to handle the DIP switches according to the expected timing


Update:

I just see that used chips are also have (different) resistor values so I guess this PCB does nothing more than loop through the cable from the chips terminal towards CN112 on the front pcb (behind the waste toner). The only thing it might do seems to add switchables resistors into the circuit, probably parallel connected.

Update:

Another thought - this tool might be permanently inside the machine correcting the resistor values in order to just install BK drums, even more easy^^
