Frequently Asked Questions about DMX and Network Equipment
6 Minute Read
PoE (Power over Ethernet) allows power to be supplied to a device over an Ethernet cable, reducing the need for additional power supplies. Our equipment uses the IEEE 802.3af (PoE) standard, which provides up to 15.4 watts per port. This is especially useful when installing devices in hard-to-reach locations or when centralized power management is required.
The bidirectional capability of DMX ports depends on the specific device. While some modern devices support bidirectional operation (especially with RDM), many DMX ports are designed for input-only or output-only operation. It's necessary to check the specifications of the specific device before use.
It protects connected devices and cables from electrical shorts, improving reliability and safety. Galvanic isolation also prevents ground loops and protects against potential differences between various parts of the system.
The maximum distance depends on the type of fiber and equipment used. For multimode fiber, typical distances are up to 2 km, while single-mode can reach 20 km or more. The ArtJet model supports up to 2000 meters when using multimode fiber.
Yes, ArtGate Arma with IP65 protection rating is designed for outdoor use. IP65 provides complete protection against dust and protection from water jets from any direction. The equipment operates reliably in temperatures from -40°C to +70°C (-40°F to +158°F) and humidity levels up to 95% non-condensing.
Use the web interface to configure parameters, including protocol type and port functionality. The web interface is accessed through a browser using the device's IP address.
A secondary IP address ensures that you can always access the device to restore settings. Additionally, most devices have a physical reset button to restore factory settings.
Yes, compact models like ArtGate Solid are designed for small spaces and convenient storage. They maintain full functionality with smaller dimensions.
RDM (Remote Device Management) allows remote configuration and monitoring of connected DMX devices. It's a bidirectional protocol operating over DMX that enables receiving device status information, changing settings, and performing diagnostics.
Regular updates ensure compatibility and optimal performance. It's recommended to check for updates at least quarterly or when adding new equipment to the system.
Yes, all devices come with a three-year warranty with the option for extension.
DMX can be transmitted over Ethernet using ArtNet or sACN (streaming ACN) protocols. These protocols allow transmission of multiple DMX universes over a single Ethernet network, significantly increasing system scalability.
DMX nodes are devices that convert Ethernet protocols such as ArtNet or sACN into DMX signals for controlling lighting fixtures. They serve as bridges between network infrastructure and DMX devices.
For DMX, shielded cables with 120 Ohm impedance are recommended. Cat5e, Cat6, or Cat6a cables can be used, with Cat6 and Cat6a being preferred for longer distances and higher bandwidth. When used for DMX over Ethernet, all these cables also support PoE up to 100 meters.
While DMX and audio equipment both use XLR-type connectors, DMX cables are specifically designed for digital data transmission with 120 Ohm impedance and enhanced shielding. Audio XLR cables typically have different impedance characteristics optimized for analog audio signals. Using standard microphone cables for DMX signals can cause data corruption and unreliable operation due to these impedance differences and insufficient shielding.
A DMX line requires termination with a 120-ohm resistor on the last device to prevent signal reflection. DMX splitters can be used to expand the system, allowing creation of multiple independent lines. The basic limitation of 32 devices per line can be overcome using amplifiers or splitters to create additional isolated segments.
DMX is a digital protocol operating at a data rate of 250 kbps, with each universe supporting 512 channels. Each DMX frame consists of a start bit, 8 data bits, two stop bits, and no parity. 5-pin DMX connectors provide additional lines for data or future expansion, although most devices use only 3 pins. Cable shield grounding is necessary for effective protection against electromagnetic interference. The protocol supports a refresh rate of up to 44 times per second for a full universe.
DMX is widely used due to its reliability, simplicity, and standardization. It's an open protocol supported by many manufacturers, ensuring equipment compatibility and component availability.
