10 MAC Aura XB user manual Linking fixtures to power in a chain If you obtain a 14 AWG / 1.5 mm power input cable and 14 AWG / 1.5 mm power relay (thru) cables from Martin™ (see Accessories on page 35), you can relay mains power from one fixture to another by connecting fixtures to power in a linked daisy-chain, MAINS OUT throughput socket to MAINS IN input socket. Using 14 AWG / 1.5 mm cables from Martin, you can link: • Maximum three (3) MAC Aura XB fixtures in total at 100-120 V, or • Maximum eight (8) MAC Aura XB fixtures in total at 200-240 V. If you install a power plug on the 14 AWG / 1.5 mm power input cable, install a grounding type (earthed) plug with integral cable grip that is rated minimum 250 V, 16 A.
Data link Data link A DMX 512 data link is required in order to control a MAC Aura XB via DMX. The MAC Aura XB has pin XLR connectors for DMX data input and output. The pin-out on all connectors is pin 1 = shield, pin 2 = cold (-), and pin 3 = hot (+). Pins 4 and 5 in the pin XLR connectors are not used in the MAC Aura XB but are available for possible additional data signals as required by the DMX512-A standard. Standard pin-out is pin 4 = data 2 cold (-) and pin 5 = data 2 hot (+). The MAC Aura XB is not subject to the limit of 32 devices per daisy-chained link which is common in Martin fixtures. Instead, the number of fixtures is either limited to 256 or limited by the number of DMX channels required by the fixtures in relation to the maximum 512 channels available in one DMX universe, whichever limit is lower. Note that if independent control of a fixture is required, it must have its own DMX channels. Fixtures that are required to behave identically can share the same DMX channels. To add more fixtures or groups of fixtures when the above limit is reached, add a DMX universe and another daisy-chained link.
