If you are installing DMX data cables, continue to the next section.
Otherwise, close the connections compartment as described in “
Access to
connections compartment ” on page 10.
Linking luminaires for DMX and
synchronized operation
You need to create a data link to:
• Control luminaires with a DMX control device.
• Operate two or more Cyclo IP65 Directionals in master/slave stand-alone
mode, where all luminaires run a synchronized light show without a
separate DMX control device.
A reliable data connection requires suitable cable. CAT 5 (category 5) UTP
(unshielded twisted pair) network cable is suitable for this purpose. The
minimum recommended wire size is 0.2 mm
2
(24 AWG) for runs up to 300
meters (1000 ft.) and 0.322 mm
2
(22 AWG) for runs up 500 meters (1640 ft).
Your Martin Architectural supplier can advise and supply suitable cable.
Luminaires on a serial data link must be daisy-chained in one single line,
maximum 500 meters (1640 ft.) long, with maximum 32 luminaires. To
exceed 32 luminaires or 500 meters, or to add branches, an optically
isolated amplifier-splitter such as the Martin RS-485 Opto-Splitter (P/N
90758060) must be used.
A male 3-pin XLR connector can be fitted at the controller end of the data
link to allow a standard connection to Martin DMX controller. The XLR
connector should be wired as follows:
• Pin 1: shield
• Pin 2: DMX - (cold)
• Pin 3: DMX + (hot)
To avoid ground (earth) loop interference, make sure that the DMX cable
shield does not come into contact with the shell or body of the XLR
connector.
A screw-type terminal block is provided in the connections compartment for
connecting the data link. The data input and data output cables must both
be connected to this terminal block. The data output may only be used to
relay data to one luminaire.
