About

node_paylink is a node library that has integration with PayLink system agregator for Self Service Betting Terminal equipment. It handles communication with Paylink Driver and communicate with bill, coin acceptors and switches as well as lightning. Escrow bill accepting is also supported if hardware has an option. (Escrow is an option where bill acceptor takes the money halfway and then you can return or accept).

Running

const paylink = require( 'node_paylink' );

//mandatory init that turns the equipment on
paylink.init({
    escrow: true, //true to turn on escrow
    serialNumber: '1234567', //optional, if you are connecting to certain paylink hardware
    disableCoinOnEscrow: true //optional to disable coin acceptors if note is in escrow
});

//if you want to enable escrow manually, not through the init method
paylink.enableEscrow(); 

//if there is money in escrow accept it
paylink.acceptEscrow();
//if there is money in escrow return it
paylink.returnEscrow();
//enable money interface (called through init)
paylink.enableMoneyInterface();
//disable money interface
paylink.disableMoneyInterface();

//turn led with ID 1 on 
paylink.ledOn(1);
//turn led with ID 1 off
paylink.ledOff(1);
//returns the number of total openings for switch ID 1
paylink.switchOpened(1);
//returns the number of total closings for switch ID 1
paylink.switchClosed(1);

//when money is inserted this event will fire, beware if escrow is on, it will fire once the escrow money is inserted and once it is accepted
paylink.on('money', (money) =>
{
    console.log('Received: '+JSON.stringify(money));
    //Received: {"insertedEscrowMoney":500,"insertedMoney":0,"totalEscrowMoney":3000,"totalMoney":31045,"changed":true,"isEscrow":true}
    //Received: {"insertedEscrowMoney":0,"insertedMoney":500,"totalEscrowMoney":3000,"totalMoney":31545,"changed":true,"isEscrow":false}

    if(money.isEscrow)
    {
        paylink.acceptEscrow();
    }
});

// if escrow money is returned either by issuing the return command or paylink returned itself money in escrow will not be deducted, escrow money is counting all money that was in escrow

//when some switch is turned on or off this event will fire
paylink.on('switch', (index, status) =>
{
    console.log('Switch with index: '+index+' is: '+status);
});

Whenever you enable money interface, escrow should be enabled too:
  paylink.enableMoneyInterface();
  paylink.enableEscrow();
