About the DDMX-S2

The DDMX-S2 is a hardware device that you can pair with Dragon Stop Motion to:

• Automate a work light (bash light) turning on and off.
• Automate front-light/back-light lighting passes.
• Automate keyframe-based lighting programs for your scene.
• Trigger a RED camera, film camera, or unsupported still camera.
• Trigger a motion-control system for shoot-move-shoot integration.
• Trigger Dragon Stop Motion from an external system.

Control Lighting

DMX512 (or DMX) is a standard protocol for controlling lighting. When paired with one or more DMX dimmer/switch packs, you can control up to 99 different light channels.

Control Devices

Interact with external devices using the built-in relay switch, digital input and digital output.

What else do I need?

The DDMX-S2 interfaces Dragon Stop Motion to one or more DMX dimmer/switch packs. You will need to buy a DMX dimmer/switch pack in order to power your lights. You can find several DMX dimmer packs at Amazon.com. Make sure that the one you choose can handle the power requirements of your lights.

You will also need a cable. If you use a 3-pin DMX dimmer pack, you can use any standard XLR microphone cable. If you use a 5-pin DMX dimmer pack, you will need a 5-pin to 3-pin adapter.

Shooting in 3D?

If you plan to shoot in 3D, make sure to check out IOTA, our new stereoscopic slider and controller designed by General Lift. It includes the same DMX and I/O functionality as the DDMX-S2.

Technical Specifications

Outputs
To prevent any possible damage to the host computer from badly grounded peripherals, all DDMX outputs and inputs are optically isolated from the host USB bus. The I/O channels "float" electrically relative to the USB, thereby minimizing the opportunity for ground loops.

DMX out
DDMX supports a USITT standard DMX512 output protocol. The DDMX output will easily drive a standard 120 ohm bus termination. The DMX channel provides packets of 199 slots, with a 50mS inter-packet period. The DMX port is typically equipped with a 3-pin XLR connector for easy connection to "entertainment" style DMX packs. To connect DDMX to a USITT standard 5-pin XLR connector for use with "professional" style equipment, use a standard 3-pin to 5-pin adapter.

Relay out
The relay is intended to switch low-power control signals like button presses, but it can also switch small amounts of power. Do not exceed 0.5A @ 24VDC, or 0.25A @ 125VAC.

Logic out
Logic out is a standard 5V, TTL level, logic signal (relative to the ground terminal. The signal is provided in both active high and active low versions. Maximum load is 30mA in each state. These signals may also be used as a differential pair with a termination load greater than 220 ohms.

SwItch in
Switch in is designed to sense a switch closure to ground. This input will also take a 5V TTL level signal. Note that in keeping with a switch closure, the logic on this pin is active low. This pin is internally pulled to 5V with a 1Kohm resister. When driving this pin externally, do not exceed 5 volts.

Physical
4.7" X 3.7" X 1.3", weight, approximately 12oz. (12cm X 9cm X 3.5cm, 340g) with 5' (1.5m) Type A USB pigtail. DDMX is built ruggedly, in a .090" thick cast aluminum box and painted with a hard powder coat to survive years in a harsh stage environment.

Power
DDMX is a "high current" USB peripheral, drawing up to 220mA with alloutputs active and fully loaded. As such it must be plugged directly into either a computer port or a powered USB hub. Your power source must provide at least 4.5 Volts. DDMX should not be plugged into a unpowered USB hub (USB peripherals send their power requirements to the system on initialization, and unpowered hbs are supposed to reject peripherals that do not identify as "low current", that is, any peripherals that require more than 100mA.
