fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut zk = ZK::new("192.168.1.201", 4370);
    
    // Set password if device requires authentication (default is 0)
    zk.set_password(12345);
    
    // Connect to device
    zk.connect(true)?; // true for TCP, false for UDP
    
    // Get user list
    let users = zk.get_users()?;
