Video Decoder Input Card; Dmxc Interface Card - Christie M Series User Manual

2.11.6Video Decoder Input Card

This card accepts and decodes standard definition (SD) video. This includes CVBS (composite video), S-
Video, and component sources. This card supports as many as 6 video signals, four of them on BNC
connectors and two on 4-pin mini-DIN connectors. Each mini-DIN connector accepts 1 S-Video signal. The
first BNC accepts composite video (only), while the remaining three BNC's can be grouped to allow one of the
following combinations:
• 3 CVBS sources on 4, 5 and 6
• 1 CVBS source, 1 S-Video source: Luma (Y) connected to 4(Sy) and Chroma (C) connected to 6 (Sc)
• 1 YPbPr source: component signal on 4 (Pr), 5 (Y) and 6 (Pb)
The video decoder input card has 8 LED indicators. The PWR LED indicates that the module is installed
properly, and has been successfully configured. The YPbPr LED indicates that a valid component signal has
been detected on inputs 4, 5, and 6 (Component input grouping must also be selected in the projector menu, see
Section 3 Operation).
signal has been detected on that input.

2.11.7DMXC Interface Card

The DMXC card is a communication interface which allows the projector to be controlled using the standard
E1.11 USITT DMX512-A protocol (DMX512-A 2008). DMX-512 is a serial protocol which is used for
controlling lighting and staging equipment from a lighting console or similar host device. ArtNET (defined by
Artistic License's Art-Net II Specification) is an Ethernet implementation of the DMX protocol. The M Series
projector supports the DMX protocol through 2 data input interfaces, 1) a DMX card and 2) ArtNET through
the Ethernet connector.
The DMXC card is not an input interface for video signals, but it plugs into a standard input card option slot.
The card can always be active, even when the projector is in standby mode. Only one DMXC card will be
allowed per system. If more than one card is installed, only the first card will be activated.
The card has two 5-pin XLR connectors - 1 (input) male and 1 (output) female. There are 2 LEDs on the
faceplate of the card: The green power LED which is on when the card is powered, and the green termination
LED which is on when termination is enabled.
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 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.

The remaining LEDs are each associated with one of the inputs, and indicate a valid
for information about setting up the ArtNET and DMX interfaces.
