LEFT and RIGHT Navigate through the option fields.
UP and DOWN Select the required value within an option field.
FUNCT Turns identify on or off for the selected devices.
ENTER Sets or programmes the selected parameter.
USER 3 second press to add or remove this menu from the shortcut list.
The option fields function as follows:
DEV Selects the RDM device. Devices are numbered from 1. A value of zero is displayed as ALL
and indicates that all RDM devices are being controlled. This is a very powerful feature but
should be treated with caution as it allows, for example, all start addresses to be set to the
same value. NB. The device number is enumerated during discovery and numbers are
allocated in the order in which devices are discovered. The order may change when
discovery is next executed.
SUB Selects the sub-device. An RDM device may have a number of sub-devices and
Commissioner is able to access 999 sub-devices. There are two special cases of sub-device.
Zero accesses the root device. ALL indicates that all sub-devices are being controlled.
PARAMETER
The RDM standard publishes numerous possible parameters ranging from start address to
pan/tilt invert. These parameters are often called PIDs. A given RDM device will typically
support a subset of the available PIDs and indeed is allowed to support a different subset
for its sub-devices. In addition, manufacturer specific PIDs are allowed where the RDM
standard does not have a suitable definition. Commissioner interrogates the selected
device / sub-device combination and allows all supported PIDs to be accessed.
DATA The data that is read (get) or to be programmed (set) into a parameter.
NB. The first release firmware has limited support for manufacturer specific parameters as the RDM
standard is currently under revision.
The following examples show how these option fields are used. In the examples we are connected to
two Artistic Licence sunDial dimmers. These are 4-channels devices that have 5 personalities and 4
sub-devices. The sub-devices can accept individual start addresses and personality.
Get the start address of the first root device
Use the LEFT, RIGHT, UP, DOWN keys to set the device to 001 and sub-
device to 000, shown in green. This is the first sunDial
’s root device .
Use the LEFT, RIGHT, UP, DOWN keys to set the PARAMETER to START
