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.
Refer to
Section 3 Operation for information about setting up the ArtNet and DMX interfaces.

Wiring Requirements
A distribution box or digital signal switcher may be used to feed the same video signal to all the units of the
tiling array. See
Figure 2-29 Use of Distribution Box .

Christie loop-through may be used to set up a tiling array (see Figure 2-29 to Figure 2-34 ). The system allows
wiring providing the HDCP requirement is met when HDCP is used by the source. The cascade level of
devices must be less than 7 levels deep.
NOTE:
If single wire loop-through is used (See Figure 2-33 ), then PIP
is not supported.
The wiring diagrams are provided to:
• Meet the HDCP requirement,
• Minimize the length of HDMI cables to be used, and
• Balance the connection tree to ensure the level of loop-through is minimized.
NOTE:
This is to enable the
downstream projectors to finish source switches in a minimum amount of time. (Applicable to arrays with
HDCP only
