Connector I/O
The SM-xx uses coaxial BNCs for the video inputs, LTC and sync inputs. Microcross
connectors are fitted for the two DVI-I inputs and one output. The GPI I/O connector is a
high density 26 way female 'D' connector. External audio connections (input or output)
are via a pair of female 37 way ‘D’ connectors, with audio monitoring outputs on a male
25 way 'D’ connector. The serial port comprises a 9 way female 'D' connector. A standard
RJ45 connector is provided for LAN connection and a USB connector on the front panel
is provided for connecting a keyboard. (A pack of mating 'D' type connectors is supplied
with the unit).
Video Inputs
All inputs (except DVI-I) are assigned to the 4 x BNC input connectors at the rear of the
unit. Up to 4 inputs can be applied if the configured video format uses a single BNC (SDI,
HD-SDI, composite). For S-Video, two connectors are required, for RGB/YUV three
connectors are required.
There are two DVI-I input connectors, as this is the maximum number of DVI-I inputs
supported per frame. All input types are assigned within the unit's system menu.
Component inputs such as YUV or RGB require three connections per channel and only
one channel can be handled per input card. However, a further two channels can be fed
via the analog pins of the two DVI input connectors (and suitably assigned in the unit's
menu) making a maximum total of six channels. Any unused BNCs can be used for other
video formats.
For Y/C, two connections per channel are required. Therefore two channels can be
handled. Any unused BNCs can be used for other video formats.
Video Outputs
The main DVI-I output supports resolutions up to HD 1080p60, 16:9 (1920 x 1080). Both
digital and analog outputs are available on this connector. Images on the output screen
can be varied continuously in size and position, cropped or displayed in pre-configured
screen layouts on a chosen colored background.
The main output is also used to display the unit's system menu when screen
configuration and set-up options are selected. This is not necessary when using external
control via the LAN.
Audio I/O
Audio levels may be displayed using up to 16 bargraphs in each tile, either superimposed
on each video image or outside active video. Audio is derived from the incoming
embedded audio (when using SDI or HDSDI inputs), or from up to 32 channels from
external analog or AES/EBU sources, for which the appropriate audio input card option
must be installed.
Additionally, external audio may be monitored using level data from the AM-xx or MADI-
xx via the LAN.
