Notes:
 DirectionofinputandoutputisgivenfromBKPro’sperspective.
 GNDiscommonfor5V_IN,DC_OUTandallinputsandoutputs.
 PowersupplyoutputispassedfromMACHINEconnectorAC1/AC2pins,canbeACorDC.
 DC_OUTderivedbyrectifyingandfilteringinputvoltageprovidedtoMACHINEconnector
AC1/AC2orAC1/GNDinputvoltage.DC_OUTvoltagedependsonactualinputvoltageandtotal
load(40Vfor24VACinput).
 BKProrequires5Vsupplyvoltage(upto64mAload)providedbycardreadertodriveoutput
signalsandreferenceinputsignals.
Attention:DonotconnectCARDconnectorAC1/AC2todevicesthathaveonlyhalf‐waverectifier(oneof
AC1/AC2isconnectedtoGND,andanotherisconnectedtosinglediode).DoingsowilldamageBKPro
andcardreaderdevice.ConnectGND/DC_OUTtothecardreaderpowerinput!
