5.0 DMX Operation
The interface uses 5 DMX channels to control the outputs. The starting address is set on the
DIP switches or via RDM protocol. The first channel controls the red output, the second chan-
nel controls the green output, and the third channel controls the blue output. This is the normal
method for DMX control. Channels 4 and 5 are used to access the special effects system. This
allows the user to set a single channel to a level to trigger a fade, strobe, or to recall a specific
preset color. During normal operation, channels 4 and 5 must be set to 0%. If either of these
channels is above 0%, the levels set by channels 1 - 3 will be ignored. Channel 4 gives access
to effects 4 - 25. Channel 5 gives access to effects 30 - 82. The mapping of specific DMX val-
ues to effect numbers is shown in a chart at the end of this document. Upon loss of the DMX
input signal, the green LED will turn off and the outputs will hold the last levels received.
6.0 RDM Operation
The interface uses ESTA’s RDM protocol to remotely set the start address. In order to enable the
RDM protocol, all 10 DIP switches must be in the OFF (down) position. When this is done, the
yellow RDM ACTIVE LED will turn on. This indicates that the DMX address is set by RDM and can
not be determined by examining the DIP switches. Using a Doug Fleenor Design RAD or similar
device, the interface can be identified, its current DMX address can be found, and its DMX ad-
dress can be changed.
To use a RAD, do the following:
Connect a RAD to the interface (all 10 DIP switches must be OFF).
•
Turn on the RAD.
•
Push the NEXT button on the RAD. This causes the RAD to attempt to discover an RDM de-
•
vice. The interface will identify itself by flashing the yellow RDM indicator and by flashing the
red outputs at the same time. The RAD will display the current DMX address programmed
into the interface. Note that the identify mode times out in about 30 seconds. Any changes
to the address should be made within this time.
Set a new DMX address using the buttons below each digit on the RAD. When the desired
•
address is displayed, push the NEXT button on the RAD. The new address will be saved to
the interface and the system will go back to normal operation. If more than one controller is
on the line, pushing the NEXT button will cause the RAD to discover another device. Note
that the discovery process will find devices based on their serial number; not by the order in
which they are wired.
The RAD is normally used to set the DMX address for the interface. It can also access
the special effects if desired. This is done by setting the address to values in the 600
series of addresses. For example, setting the address to 601 will access effect 1 and
setting the address to 630 will access effect 30.
