ZKLibrary is PHP library for reading and writing data to attendance device using UDP protocol. This library useful to comunicate between web server and attendance device directly without addition program. This library is implemented in the form of class. So that you can create an object and use it functions.
maybe you forget to but Port, or the protocole
$zk = new ZKLibrary('192.168.2.200', 4370,'TCP');
try this maybe it will work
or just show us how you are connecting, like just sent the connection line
