Tips for reliable data transmission
Use shielded twisted-pair cable designed for RS-485 devices: standard
microphone cable cannot transmit control data reliably over long runs. 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. The pinout on all
connectors is pin 1 = shield, pin 2 = cold (-), and pin 3 = hot (+). Pins 4 and 5
in the 5-pin XLR connectors are not used in the fixture but are available for
possible additional data signals as required by the DMX512-A standard.
Standard pinout is pin 4 = data 2 cold (-) and pin 5 = data 2 hot (+).
To split the link into branches, use a splitter such as the Martin DMX 5.3
Splitter or RDM 5.5 Splitter.
Terminate the link by installing a DMX termination plug in the output socket
of the last fixture. The termination plug, which is a male XLR plug with a 120
Ohm, 0.25 W resistor soldered between pins 2 and 3, “soaks up” the control
signal so it does not reflect and cause interference. If a splitter is used,
terminate each branch of the link.
Connecting the DMX data link
To connect the fixture to data:
1. Connect the DMX data output from the controller to the first fixture’s
male XLR DMX input connector.
2. Connect the first fixture’s DMX output to the DMX input of the next fixture
and continue connecting fixtures output to input. Terminate the last
fixture on the link with a DMX termination plug.
Fixture setup
This section explains the fixture characteristics that can be set to determine
how it can be controlled and will behave. These settings are made using the
menus available in the control panel. Settings are retained in memory when
the fixture is powered off.
A complete map of the control menu structure and brief explanations of their
purposes can be found in ‘Control menus’ on page 24.
