{
    // Blink each output in increasing order
    foreach (var channel in digitalOutputModule0.Channels)
    {
        channel.Blink();
    }

    // Blink each output in decreasing order
    foreach (var channel in digitalOutputModule0.Channels.Reverse())

        channel.Toggle();

        // Delay for 50ms
        Thread.Sleep(50);

        // Toggle the channel's state again
        channel.Toggle();
    }

    public static void Toggle(this DigitalOutputModule.Channel channel)
    {
        // Toggle state
        channel.State = !channel.State;

        // Write the state to the module
        channel.Module.Header.Sync();
    }
