Moving head beam lights are a popular lighting option in the entertainment industry, used in concerts, theatres, and nightclubs. They offer versatile lighting effects thanks to their ability to control pan and tilt movements. Pan and tilt are two fundamental movements that allow moving head beam lights to project light in various directions. Pan refers to the horizontal movement of the light fixture, moving it from left to right or vice versa, while tilt controls the vertical movement, enabling the light to move up and down. By mastering these movements, lighting designers can create dynamic effects and stunning lighting displays. In this discussion, we will explore the steps to move pan and tilt DMX lighting, the industry standards, and the programming concepts involved.

What You'll Learn
Understanding pan and tilt
DMX (Digital Multiplex) is a standard for digital communication networks that are commonly used to control lighting and effects in theatrical and concert productions. Pan and tilt refer to the horizontal and vertical movements of a light fixture, respectively. By adjusting the pan and tilt angles, you can control the direction and position of the light beam.
The pan and tilt movements of a DMX light fixture are typically controlled via a 16-bit resolution, which provides finer control over the movement compared to an 8-bit resolution. Each movement is controlled by two DMX 512 frames, with one frame for each attribute (pan or tilt). This allows for precise positioning and movement of the light beam.
The home position for pan and tilt on most DMX lights is 50:50, which means the light is positioned with maximum movement available in each direction before reaching a pan-stop or tilt-stop. From this home position, you can adjust the pan and tilt angles to move the light beam accordingly. For example, increasing the pan angle will move the light to the left or right, while increasing the tilt angle will move the light up or down.
It is important to ensure that all lights are set up with the same orientation to achieve consistent and predictable results. Additionally, some lighting designers configure their fixtures to work seamlessly with their trackball, allowing for intuitive control over the pan and tilt movements.
By understanding the principles of pan and tilt in DMX lighting, lighting designers can create dynamic and precise lighting effects, enhancing the visual experience of any performance or event.

DMX channel functions
DMX, or Digital MultipleX, is a communication protocol that allows for the transmission of digital commands from a control device to digitally addressable lighting fixtures. Each fixture is assigned a DMX address, which is another name for a channel, and this enables individual control of each fixture's capabilities.
DMX channels have a range of values from 0-255, which correspond to 0-100% output or various fixture functions and presets. The functions available depend on the channel mode of the fixture, with each mode offering different functions. For example, a 4-channel mode fixture will only allow control of the first four functions, whereas a 7-channel mode fixture will offer more.
The specific functions of each channel are predetermined by the manufacturer, and these are referred to as the fixture's "personality". For instance, a 5-channel LED fixture may have the following functions: Channel 1: Dimmer, Channel 2: Red, Channel 3: Green, Channel 4: Blue, and Channel 5: Shutter/Strobe.
Some fixtures use two channels for parameters that require greater accuracy, such as Pan and Tilt. This provides 16-bit precision, with the first channel controlling the coarse movement and the second controlling the fine movement. This allows for much greater accuracy in the movement of the fixture.
It is important to note that the orientation of fixtures can be configured to ensure they all move in the same direction. For example, one user configures their fixtures so that "increasing tilt moves towards upstage, with positive tilt, increasing pan moves stage left". This ensures consistency in the movement of the lights.

Programming DMX lights
DMX (Digital Multiplex) is a protocol commonly used in stage lighting and live entertainment to control the movement, colour, and intensity of lighting fixtures. Each fixture is assigned a unique address that determines which control signals it responds to. To control a DMX-enabled light fixture, you need a DMX controller, which acts as the interface between you and the lighting fixtures. The controller sends commands to the fixtures through a DMX cable, which looks like a standard XLR microphone cable.
DMX channels are the building blocks of DMX programming. Each channel represents a specific attribute of a lighting fixture, such as colour, intensity, or movement. For example, a fixture with RGB capability would have three separate channels for red, green, and blue. The DMX controller sends signals through these channels to control the attributes of the fixture. It is important to ensure that the DMX channels on the controller match the channels set on the lighting fixtures for proper communication.
You can create scenes by setting specific values for each DMX channel. Scenes are pre-programmed looks or settings that can be recalled instantly during a performance or event. By adjusting the intensity levels of the red, green, and blue channels, you can produce the desired colour. Once programmed, scenes can be easily recalled, allowing for seamless transitions and dynamic lighting effects.
When programming DMX lights, it is important to consider the pan and tilt of the fixtures. Pan and tilt are often controlled via 16-bit resolution, or two channels. The manual will specify which is the high or low byte. By adjusting the pan and tilt channels, you can control the direction and angle of the light beam.
Additionally, it is important to ensure that all your lights are oriented in the same way. You can set your pan and tilt DMX inverts and offsets so that when all moving fixtures are pointed straight out at 90 degrees, they move in the same direction. This ensures that your movement effects and position presets always look as intended.

Setting movement speed and positioning
To set the movement speed and positioning of DMX lighting, it is important to first understand the basic programming concepts. Familiarize yourself with the lighting controller's interface, programming features, and fixture parameters. Know how to assign DMX channels, as this will make the programming process smoother and more efficient.
The "Home" position for pan and tilt on most DMX lights is 50:50 (or 32767:32767). This position allows for maximum movement in each direction before encountering a pan-stop or tilt-stop. For example, for a light with a total pan range of 360 degrees, a control channel set to half would result in 180 degrees. Taking the control channel to full will move the light 180 degrees off-axis towards a stop. So, a value of 50% means "go to Home", while a value of 100% means "go to the pan-stop 180 degrees from Home".
To set the movement speed and positioning, determine the desired angles and the duration of each movement. For instance, you may want the lights to pan from left to right for 10 seconds, then tilt upwards for 5 seconds before returning to the starting position. Break down the lighting effects into sections or scenes, and experiment with different speeds, acceleration rates, and positioning options to achieve the desired effect.
Additionally, consider using features such as pan/tilt curves, which allow for smoother and more realistic movements. Regularly save your programming to prevent any loss of work, and test the programmed movements multiple times to ensure they align with your vision. Fine-tuning may be required to achieve the desired accuracy and fluidity.

Using a tracking system
Video Tracking:
A video camera or web camera can be used for position detection, offering a simple and cost-effective solution. Software like Video Follow Spot allows you to track a target and adjust the pan and tilt of the lighting automatically. This method is flexible and does not require specialised knowledge or expensive equipment.
Motion Controller:
Devices like Kinect or similar motion controllers can be utilised for automatic pan and tilt adjustments. However, it's important to consider their limited range and viewing angle when positioning the sensors.
Tracking Packs:
While they can be costly, tracking packs are another option for automating pan and tilt movements. These systems use a tracking device attached to the target, allowing the lighting to follow their movements. Examples include the Martin TrackPod, PRG GroundControl, and BlackTrax by Cast Soft.
It's worth noting that some tracking systems offer advanced features, such as the ability to identify and track multiple targets in real time, making them suitable for complex performances with multiple performers.
To integrate a tracking system with DMX lighting, it is essential to assign DMX addresses to each lighting unit. This ensures that the lighting units respond to the correct DMX commands. Additionally, you can utilise software and interfaces to control which signals are sent down each of the DMX channels, allowing for precise control over the pan and tilt movements.
