Dont open comunications on device BV20

[unixunamed]

Ubuntu 22 node 19.9.0

Hello, sorry to bother you, but I'm really racking my brain, I'm using your code to try to read banknotes from a BV20 bill acceptor, I configure the correct port to which a USB TTL adapter with Tx + RX + GNT correct cables and bill acceptor configured for SSP however I can't make it work, it gives me the timeout message: Port opened!
WITH <- 7f0001116608 null 0
TIMEOUT SYNC
my code .. :

const { SerialPort } = require('serialport');
const sspLib = require('encrypted-smiley-secure-protocol');
//const sspLib = require('./src/index');

letport;
let eSSP;

async function findDevice(vendorId = '067b') {
console.log(" LOG SerialManager Find VENDORID",vendorId);

 const ports = await SerialPort.list();
 const device = ports.find(port => port.vendorId === vendorId);
 console.log(" LOG SerialManager DEVICE",JSON.stringify(device));

return device ? device.path: null;

}

async function setupSSP(devicePath) {
devicePath = '/dev/ttyUSB1';
console.log('LOG SERIAL MANAGER SETUP-SSP DEVICE = .' , devicePath);

 if (eSSP) {
     console.log('SSP already configured.');
     return;
 }

 eSSP = new sspLib({
     id: 0x00,
     debug: true,
     timeout: 3000,
     fixedKey: '0123456701234567',
 });

 eSSP.on('OPEN', () => {
     console.log('SSP open');
 });

 eSSP.on('NOTE_READ', result => {
     console.log('Note read:', result);
     // Here you add the read note processing logic
 });

 eSSP.on('NOTE_REJECTED', result => {
     console.log('Note rejected:', result);
 });

 try {
     console.log(">>>>>>>> >>>

THE SYSTEM STOP HERE HERE IS A PROBLEM >>>>>>>>>>>>>>>>>>>>>> >>");
await eSSP.open(devicePath);
console.log("SERIAL MANAGER >> TRY >> THEN OPEN >>");

     await eSSP.initEncryption();
     console.log("SERIAL MANAGER >> TRY >> BEFORE ENABLE >>");

     await eSSP.enable();
 } catch (error) {
     console.error('Error configuring SSP:', error);
 }

}

function closeSSP() {
if (eSSP) {
eSSP.close();
eSSP = null;
}
}

module.exports = { findDevice, setupSSP, closeSSP }; Please help me!
