Radio Frequency Interference and Immunity
This unit generates, uses, and can radiate radio frequency energy. If the unit
is not properly installed and used in accordance with this guide, it may cause
interference with radio communications. Operation with non-certified periph-
eral devices is likely to result in interference with radio and television recep-
tion. This equipment has been tested and complies with the limits in accor-
dance with the specifications in:
- FCC Part 15, Subpart B
- CE EN50081-1:1992
- CE EN50082-1:1992.

1.0 SDM-875p HDTV Serial Digital to Component VGA/DVI Converter
1.1 Introduction
The SDM-875p is a High Definition digital converter converting
serial digital HDTV (SMPTE 292M) to High Definition Component
Analog/Digital (Y/Pb/Pr and RGB). The SDM-875p provides auto-
matic input scan rate detection and supports a wide variety of
input formats including 525i, 625i, 720p, 1080i and 1080p. Output
formats are compliant to EIA/CEA-861-B standard. The primary
application is to convert HD serial to Component Analog/Digital
for the purposes of feeding an HDTV monitor, computer monitor
and projector. (CRT, LCD, Plasma, DLP, D-ILA etc). In order to
support the emerging popularity of 24p equipment and digital dis-
play, the SDM-875p provides VGA and DVI output with selectable
3:2 sequence insertion.

2.0 Overall View
Figure 2 illustrates the SDM-875p's major parts and their loca-
tions. A high-definition or standard definition digital video source
is connected to the HD/SD SDI IN BNC and the Component
Analog/Digital output is provided by the DVI-I connector. Error
status is provided by the status LED. Finally, the power source is
connected to the lockable power connector.

3.0 Installation
3.1 Power Supply
The power supplies LKS-WSU, for 110 V and 220 V operation, is
used to power the SDM-875p. The power supply provides a re-
gulated +5 [email protected] A power source. The SDM-875p employs
a mini XLR-3 connector for its power needs. Figure 3 provides a
detailed pinout of the male connector.

3.2 HD/SD Serial Digital Video Input with Active Loop-
Through
Connect a high-definition or standard definition digital video sig-
nal to the BNC labeled HD-SDI IN. The high-definition serial dig-
ital input signal must conform to the SMPTE 292M standard.
The standard definition serial digital input signal must conform to
the SMPTE 259M-C standard.
Make sure that the input signal cable has a maximum length of
75m (250’) and that all serial digital video equipment are con-
nected point-to-point. For instance, there must be a point-to-
point connection between the HD/SD SDI IN BNC and the source
equipment. If a T-connector is used to connect other equipment,
the maximum specified cable length is no longer valid.

3.3 High Definition Component Analog/Digital Video Output
The high definition component analog/digital video output signal
(Y/Pb/Pr and RGB) is provided by the DVI-I (female) labeled
OUTPUT. A DVI-to-VGA adapter is supplied for analog output.
The output format is automatically selected according to the input
signal; for a complete list of the output formats and related
SMPTE standards refer to section 5 Specifications.

Slide Switches selection:
Test Pattern Selection
On: Set the “Test” slide switch to this position to enable
the test pattern on output. The test pattern consists
of a HDTV color bars.
Off: The test pattern is disabled.
Note: in order to output a test pattern, a valid input signal must
be installed.

Markers 4:3 Selection:
On: Set the “Markers 4:3” slide switch to this position to
display 4:3 markers on the 16:9 image.
Off: The 4:3 markers are disabled.
Input format
I: Set the “Input Format” slide switch to this position
for most input signal.
PsF: Set the “Input Format” slide switch to this position
to access additional output format when input format
is 1920x1080 25PsF.
Output format
GBR: For GBR CAV output, set the slide switch to this posi-
tion.
YPbPr: For Y/Pb/Pr CAV output, set the slide switch to this
position.
CS (Composite Sync) on CAV
All: Set the slide switch to this position to add sync to the
color components of the signal. Composite sync is
bi-level for GBR output and tri-level for YPbPr
output.
None: Set the slide switch to this position to output separate
H and V sync.
