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.

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

• Minimize the length of HDMI cables to be used, and
• Balance the connection tree to ensure the level of loop-through is minimized.
