Maxedia 4
Connecting DMX Devices
The Maxedia has 5-pin XLR sockets for DMX input and output. The pin-put on all sockets is pin 1 to
shield, pin 2 data cold/compliment (-), and pin 3 to data hot/true (+).
Use shielded twisted-pair cable designed specially for DMX devices: standard microphone cable
cannot transmit control data reliably. 24 AWG cable is suitable for runs up to 300 meters (1000 ft.)
Heavier gauge cable and/or an amplifier are recommended for longer runs.
To split the DMX link into multiple branches, use a splitter such as the Martin 4-Channel Opto-
Isolated RS-485 Splitter/Amplifier. Never use a Y-cable.
Do not overload the link. Up to 31 additional devices may be connected on any given DMX link.
Terminate the link by installing a 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 watt 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. Please note that some fixtures and dimmers provide
onboard termination and do not require an external terminator. Consult the users manual of the
DMX device for details.
Martin fixtures introduced before 1997 have reversed polarity data sockets (pin 2 + and pin 3 -). The
socket polarity is labeled. Use a phase-reversing cable between the Maxedia and any device with
reversed polarity.
