Section 3: Operation
DMX / ArtNET - Submenu
The projector supports the DMX512 protocol through both the DMXC option card and through the ArtNet
communications via the Ethernet connector. Both input methods share the same feature list, and can share the
same configuration methods as follows:
• The user may select to monitor both, neither, or a single interface via a DMX control
• If both interfaces are selected, the DMXC input card will take priority if it is actively receiving data. While
data is active on this card, ArtNet packets will be ignored.
• Only 1 DMXC card can be used at a time. If more than one is populated, the 2nd and subsequent cards will
not be activated.
• The DMXC card will always be active, even when the projector is powered down (i.e. in standby mode).
• 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.
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.
• Basic (20 channels): This is the default setting. The 20 basic channels are those controls which are
expected to be used throughout the course of an actual show (ie. shutter, channel change)
• Advanced (64 channels): This includes all the functionality of the "Basic" channels plus additional con-
trols for setup.
Refer to Appendix C: 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 basic personality (20 channels), projector 1 should start at base channel 1
and projector 2 should start at base channel 21.
The Base channel setting must allow enough space for the channels required by the selected personality
NOTE:
.i.e. If the Basic Personality is selected, the Base Channel may be in the range 1-492. If the Advanced
Personality is selected, the Base Channel may be in the range 1-448.
• 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 that 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
