Black Box is delivered with built-in AC/DC that accepts 90-250V universal power supply and delivered with standard RP-SMA to follow ETSI and FCC regulations. With a different antenna the outdoor model is able to transmit wireless in line of sight up to 20km between transmitter and receiver. It is also possible to link a transmitter and receiver together to create a 'virtual repeater' to avoid line of sight problems, say the company. A complete set of accessories with different antennas and cables is available to complete the range.
W-DMX Black Box IP65 Outdoor is based on the PLASA Innovation Award winning W-DMX Black Box for indoor use, and uses the same features such as adaptive frequency hopping, which the company says can change frequency over 1000 times per second to avoid interference. It's also protected with a unique PIN code, so each system only listen to each other and by default avoid all other traffic that are in the 2.45GHz band. This makes it possible to run 16 DMX 512 universes (8192 channels) on same spot "without interference", the manufacturer claims.
The system can be used 'point to point' between the console and first fixture and then cable linked to all other units connected in the same universe, or 'point to multipoint', where each fixture has its own receiver; in both cases all receivers receive the complete DMX Universe of 512 channels, say the company.
