USB peripherals send their power requirements to the system on initialization, and unpowered hubs are supposed to reject peripherals that do not identify as “low current,” that is, any peripherals that require more than 100mA.3d character animation programs are a massive part of the software world these days. DDMX-S2 should not be plugged into a unpowered USB hub. Your power source must provide at least 4.5 Volts. As such it must be plugged directly into either a computer port or a powered USB hub. PowerĭDMX-S2 is a “high current” USB peripheral, drawing up to 220mA with all outputs active and fully loaded. 090″ thick cast aluminum box and painted with a hard powder coat to survive years in a harsh stage environment. ( 340g) with 5′ ( 1.5m) Type A USB pigtail. When driving this pin externally, do not exceed 5 volts. This pin is internally pulled to 5V with a 1Kohm resister. Note that in keeping with a switch closure, the logic on this pin is active low. This input will also take a 5V TTL level signal. Switch in is designed to sense a switch closure to ground. These signals may also be used as a differential pair with a termination load greater than 220 ohms. The signal is provided in both active high and active low versions. Logic out is a standard 5V, TTL level, logic signal (relative to the ground terminal). The relay is intended to switch low-power control signals like button presses, but it can also switch small amounts of power. To connect DDMX-S2 to a USITT standard 5-pin XLR connector for use with “professional” style equipment, use a standard 3-pin to 5-pin adapter. The DMX port is typically equipped with a 3-pin XLR connector for easy connection to “entertainment” style DMX packs. The DMX channel provides packets of 199 slots, with a 50mS inter-packet period. The DDMX-S2 output will easily drive a standard 120 ohm bus termination. DMX outĭDMX-S2 supports a USITT standard DMX512 output protocol. The I/O channels “float” electrically relative to the USB, thereby minimizing the opportunity for ground loops. To prevent any possible damage to the host computer from badly grounded peripherals, all DDMX-S2 outputs and inputs are optically isolated from the host USB bus. If you use a 5-pin DMX dimmer pack, you will need a 5-pin to 3-pin adapter. You must use a cable designed for DMX, not a microphone cable.
Make sure that the one you choose can handle the power requirements of your lights. You can find several DMX dimmer packs at. You will need to buy a DMX dimmer/switch pack in order to power your lights. The DDMX-S2 interfaces Dragonframe to one or more DMX dimmer/switch packs. Interact with external devices using the built-in relay switch, digital input and digital output. When paired with one or more DMX dimmer/switch packs, you can control up to 99 different light channels.
