  $pjlink = new PJLink();
  if (false === $pjlink->powerOn("192.168.0.1")) {
    echo $pjlink->getError();
  } elseif (false === $pjlink->setInput(11, "192.168.0.1")) {
    echo $pjlink->getError();
  }

// Example 2

  require_once('pjlink.class.php');
  $pjlink = new PJLink(1);
  $pjlink->setDevice("192.168.0.1", "my_pjlink_pass", 10, 4352);
  if (false === $pjlink->powerOn()) {
    echo $pjlink->getError();

// Example 3

  require_once('pjlink.class.php');
  $pjlink = new PJLink(2);
  $pjlink->setDevice("192.168.0.2", "my_pjlink_pass", 10, 4352);
