18 VDO Dotron User Manual
Installing a DMX-controlled system
In a DMX-controlled system, an RDM-compliant DMX lighting controller sends a DMX control data signal
over a DMX link to the installation, and then over the hybrid link to the VDO Dotron dots.
The DMX link requires DMX cable. It can be maximum 300 m (1000 ft.) in length and must run in one single
daisy-chain, but it can be extended or split into branches using an RDM-compliant amplifier/splitter such as
the Martin® RDM 5.5 Splitter (P/N 90758150). Alternatively, you can run the DMX signal from the controller
over Ethernet cable using Art-Net protocol and convert it to a DMX-compliant signal with an Art-Net to DMX
converter.
If you would like assistance with creating a DMX link, your Martin® supplier will be glad to advise.
The number of VDO Dotron dots that you can control on one DMX link is limited by the number of DMX
channels the dots will use and the 512 DMX channels available in one DMX universe at the DMX controller.
Each time you have used 512 channels, you must create a new DMX link that is connected to a new DMX
universe on the controller. Note that this limit applies to the
DMX link . The maximum safety limits that apply
to the chain of dots and cable (see “Safety limits for connecting devices” on page 7) take priority and must
be respected in all cases.
If you need to take the DMX signal from the end of a chain of VDO Dotron dots, connect a DMX Lead-out
Cable (see “Cables” on page 35) to the output connector of the last dot on the chain. The Lead-Out Cable
has a 5-pin female XLR connector with standard DMX pinout (pin 1 = shield, pin 2 = data cold/negative, pin
3 = data hot/positive, pins 4 and 5 are not used) that lets you draw off the DMX signal.
DC Power options in DMX installations
A DMX-controlled VDO Dotron installation can be supplied with DC power from the Martin® IP66 PSU
240W external power supply unit (previously called the Martin® Tripix Power IP66) or from a generic
external PSU (the Mean Well SP-480 48, for example).
The hardware and cables required are slightly different depending on which type of PSU you use to supply
the installation with DC power. The two different types of installation are covered in the next two sections:
• If you are using a Martin® IP66 PSU 240W, see ”Installing a DMX system using the Martin® IP66
PSU 240W” on page 19.
• If you are using a generic 48 VDC PSU, see ”Installing a DMX system using a generic external 48
VDC PSU” on page 21.
