• 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.
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.
• INPUT NOISE FILTER
The Input Noise Filter eliminates DMX/ArtNet input oscillation, which can occur on some DMX control
boards. This can cause fine resolution controls (e.g. Lens, Brightness) to continually change. A filter setting of
0 will turn off the filter; a setting of 1 will filter +/- 1 step changes, etc. Using this filter will decrease the fine
control precision of some slider controls. By default this filter is set to 0 (Off). It is not recommended to use
this feature unless you are experiencing problems with your DMX input.
• HOST NAME
This will be used to respond to ArtNet polling queries. "Christie" will be the short name, "Christie_HostName"
will be our long name. By default the host name is composed from the projector name and serial number.
(Default = "<unit name>_<serialno>").
