System setup

Different modes can be mixed freely in an installation. For example, some VDO Fatron fixtures can be set to
RGB mode, some set to Basic mode and others to Pixel mode. All you need to do is set up fixtures, DMX
addresses and DMX channel allocation correctly.
DMX addresses
To prepare an installation for DMX control, you set it up using an RDM-compliant DMX controller so that
fixtures or pixels receive instructions from the controller on their own DMX channels. The DMX address
(also known as the control address or start channel) is the first of these channels. A VDO Fatron fixture or
pixel uses more than one channel, so it uses the DMX address channel and the channels immediately
above it. For example, one VDO Fatron fixture set to RGB mode and set to DMX address 1 will use DMX
channels 1 - 3. Channel 4 will be available for use as a DMX address for the next device.
Setting up via RDM using Martin® M-PC
Using an RDM-compliant DMX controller such as Martin® M-PC, you can communicate with the VDO
Fatron fixtures on the DMX data link via RDM. You can:
• Retrieve data
• Set the DMX addresses of the fixtures and set their DMX mode
• Apply various setup options.
To use Martin® M-PC, connect a PC running this application to the data link using the Martin® M-DMX
USB/DMX interface box.
For more information about setting up fixtures for DMX control, see the Martin® M-Series controller user
documentation.
