c3-200 not working here

[iojancode]

Hi, im having troubles connecting, any help would be appreciated

this is the test

var ZKLib = require("zklib");

ZK = new ZKLib({
  ip: '192.168.86.21',
  port: 4370,
  inport: 5200,
  timeout: 5000,
  connectionType: 'tcp',
});
    
    // connect to access control device
    ZK.connect( function() {
    
      // read the time info from th device
      ZK.getTime( function(err, t) {
        console.log("Device clock's time is " + t.toString());
        
        // disconnect from the device
        ZK.disconnect();
      });
    });

this is the failure

events.js:160
      throw er; // Unhandled 'error' event
      ^

Are C3's known to work with this library? The protocol on the wire looks entirely different but perhaps that's a firmware change...

I don't think so, this error indicate that tcp connection is not the right connectiontype ( may be is udp is true ) or some device also connect to this device then you can't connect to it
