Looking for some help here getting the cash drawer to open. Its driving me crazy.
Printer: Ithaca Itherm 280
Cash Register: https://www.amazon.com/gp/product/B01FY8AGWE/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
Tried all standard codes: 27,112,0,48,251 27,112,1,49,251
Nothing is happening. I do know the command is sending because I have had printer activity from the automation command. Is it possible that the cash drawer needs a different the pulse on a different pin? Not really sure where to go next.
