Section 2: Installation and Setup
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

Twin DisplayPort Input Card
The Twin DisplayPort Input card 1.1a inputs from one or two DisplayPort sources. The card has two
DisplayPort outputs, each of which is a loop through for its respective input (loop through of encrypted content
is not supported). Five LEDs are on the card faceplate. The PWR on the left side indicates power is applied and
the card is initialized. The LEDs on the right side of the corresponding connectors indicate a valid signal is
detected. In the case of the output, the LED indicates a signal is currently being looped out.
