Getting Started With Patching 19
Discovery
RDM automatically discovers RDM-capable lights. Discovery runs continuously any time the Patch
screen is open and the RDM buttonîis enabled, and will repeatedly search for devices. As devices are
added or removed from a system, they will be updated in the patch list.
Note: Discovery takes place during short periods of rest of normal DMX transmission and is a
lengthy process to complete. You should expect at least several seconds of delay to discover a
light on a small system and much longer delays on a very large system.
Addressing and Mode
RDM allows you to set the DMX address and the operating mode of a light remotely.
Setting the operating mode may change the footprint, which is the number of DMX addresses occupied by
the device. If you change the mode of a device adjacent to some other device or dimmers in patch, the new
mode could be larger than the available space and overlap already used DMX addresses. When this hap-
pens, the affected channels are indicated in the patch list in red, and you will need to take corrective action
and re-patch.
The Patch system knows how to match the chosen mode with the correct personality.
Universe
You cannot change the Universe part of the DMX patch for a Device found by RDM. RDM can only operate
on the one universe it is connected to. To change the universe a light is patched to, you must physically re-
plug the light to another DMX cable.
