Section 3: Operation
• When controlling a projector with DMX, it is recommended that no other interfaces (such as the IR Remote
or Web interfaces) are used.
• The Menu for setting the ArtNET and DMX interface is always available at:
Configuration > Communications > DMX/ArtNET Settings.
NOTE: When a DMXC card is installed, the same menu is available at:
Configuration > Option Card Settings > DMX Input Card > DMX/ArtNET Settings.
• DMX Interface: Select whether to monitor the DMXC input card only, the ArtNET interface only, both
(ArtNET is ignored if the DMXC card is actively receiving data), or neither.
• DMX Personality: This control determines how many contiguous channels the projector will respond to.
Fewer channels mean more devices can be used per universe. More channels mean greater control of the
projector, but fewer devices.
• Show Personality (18 channels): This is the default setting. The 18 Show channels are those controls
which are expected to be used throughout the course of an actual show (ie. shutter, channel change). These
channels are a subset of those in the Setup Personality.
• Setup Personality (38 channels): The 38 Setup channels are those controls which are expected to be used
during the setup of an actual show (ie. Projector orientation, Color, Brightness, etc.)
• Nitro Personality (25 channels): The Nitro personality includes channels with Load/Execute style func-
tionality for 'critical' functions that require security so that they cannot be changed by a single button press
and will not be affected by a Grand Master. This personality cannot be used with a control board contain-
ing only sliders. The Load/Execute channels operate as follows:
• The user must load a value, then send 86 (LOAD), then send 171 (EXECUTE) to execute the loaded
value
• If this sequence of 3 values is not sent to the projector, the command is ignored
See Appendix B: DMX / ArtNET
• Base Channel: There are 512 channels per universe. This control specifies the starting channel for this
projector. If multiple projectors are used on the same universe and are to be controlled independently, this
value must be changed. i.e. If both projectors are using the Show personality (18 channels), projector 1
should start at base channel 1 and projector 2 should start at base channel 19.
NOTE: The Base channel setting must allow enough space for the channels required by the selected
personality (i.e. If the Show Personality is selected, the Base Channel may be in the range 1-494). If the
Setup Personality is selected, the Base Channel may be in the range 1-474.
• Software Termination: This control supplies a signal to the card to switch termination resistance in/out of
the circuit. It may be necessary to clear this setting upon card removal. By default SW termination is
disabled. The Input termination (2 Watt, 120 Ohm) is required on the last DMXC card in a loop through
configuration. (i.e. only on the last projector). Termination may be either hardware (by plugging in a
termination dongle, etc) or may be switched in by software, but should not be both.
NOTE: Hardware termination is recommended, because software termination is only in place when the
projector has AC applied. If there are cases where the network is required to be terminated without AC
applied to the last projector, then a hardware terminator should be used
• ArtNET Universe: For DMX512, each universe represents a separate electrical circuit (up to 512 devices/
channels). For ArtNET however, 'DMX' data is broadcasted over an Ethernet network, so every device will
receive every packet of data, whether they belong to that universe or not. This control specifies which
universe the projector belongs to, so it can filter out all other data packets. The Universe applies to ArtNET
only, and does not apply to the DMXC input card.
• ArtNET Subnet: This is the highest level address in an ArtNET network, providing expandability beyond
the universe level. This control specifies which ArtNET subnet (group of universes) the projector belongs to.
The Subnet applies to ArtNET only, and does not apply to the DMXC input card.
