Data links
Important! Shut down power to the fixture before connecting to or disconnecting from data.
The MAC Ultra Performance has two pairs of connectors for control data In/Out:
• one pair of XLR sockets ( A in Figure 8), and
• one pair of etherCON sockets ( B in Figure 8).
Use only one socket type –
either
XLR
or
etherCON – at any one time.
Data via DMX cable
The MAC Ultra Performance has 5-pin locking XLR sockets (see A in Figure 8) for DMX and RDM input and
output via DMX cable. The default pin-out on both sockets is:
• pin 1 to shield
• pin 2 to data 1 cold (-)
• pin 3 to data 1 hot (+).
Pins 4 and 5 are not used by the fixture but are bridged between input and output sockets. These pins can
therefore be used as a pass-through connection for an additional data signal if required.
Tips for reliable data transmission via DMX cable
• Use shielded twisted-pair high-quality DMX cable.
• 24 AWG cable is suitable for runs up to 300 meters (1000 ft). Heavier gauge cable and/or an amplifier is
recommended for longer runs.
• Do not use microphone cable, as standard microphone cable does not have the correct impedance and
cannot transmit control data reliably over long runs.
• To split the data link into branches, use an optically isolated splitter-amplifier.
• Do not overload the DMX data link. You can connect up to a maximum of 32 devices on a serial DMX link.
• Install a DMX termination plug on the last fixture on the link.
Connecting to data via DMX cable
To connect the MAC Ultra Performance to DMX and/or RDM data carried over DMX cable:
1. Shut down power to the fixture.
2. Connect the DMX data output from the controller to the MAC Ultra Performance’s data input (male XLR)
socket using good-quality DMX cable.
3. Run DMX cable from the MAC Ultra Performance’s data output (female XLR) socket to the data input of
the next fixture and continue until the link is complete.
