Section 2: Installation and Setup
Video 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 & 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) & 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's menu -
see Section 3 Operation.
signal has been detected on that input.
DMXC 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 / staging equipment from a lighting console or similar host equipment. 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.
Unlike the other optional input cards, 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 powered down
(i.e. in standby mode). Only one DMXC card will be allowed per system. If more than one is populated, the
2nd and subsequent cards will not be activated.
The card has two 5pin XLR connectors - 1 (input) male and 1 (output) female. There are 2 LED's 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.

The remaining LEDs are each associated with one of the inputs, and indicate a valid
