Thesesignals come from the automatic cash-point. The specific RS485 cable (A) must beused.The 24Volt board power supply must be connected on Pin1 and Pin2 This cablecomes from the automatic cash-point. The standard bipolar (B) must be used.Connector CN2This is the (washing/drying) machine activation connector.The “Common” signal reaches Pin1, while on Pin2 there is the NC relay contact andon Pin3 the NO contact.Connector CN3This connector replicates the same activation signals as connector CN2Its activation times are a 10 thof CN2. (for washing machines that require quickactivation time).Connector CN4The board can read signals coming from the washing and drying machines, such as“Machine Busy” and “Machine powered”. These inputs are used to signal when themachine is already in operation and when the machine is powered. The input interfacewith the BIO board is opto-isolated.A 12 Vdc power supply is present on this connector, should themachine signals be voltage-free contacts, such as relays. Thispower supply can be brought to the machine voltage-free contactheads and the signal can be brought to the BIO board inputs.25
