Letpos board will accept the nayax vpos mdb card reader payment credit and convert it to the pulse output according to the price of the pulse/credit. letpos also can accept the payment from coin acceptor and bill acceptor.
Letpos board, that output is NPN open-C output (the same as the pulse type coin acceptor). also Letpos board has a relay version, it has a relay output (when received the preset credit payment ,then relay will be shorted for a preset time) So for NPN Open-C output type, we provide two wire output and for RELAY output type , It has a output terminal on board (NO, COM, NC)
