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-872p SD/HD Serial Digital to DVI-HDTV Converter
1.1 Introduction
The SDM-872p is a miniature, digital video interface converting
SDI and HDSDI video signal to Digital RGB (DVI-HDTV, DVI-
SDTV) without resizing. The SDM-872p provides automatic 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 SD and HD serial to Digital RGB for the purposes of
feeding a computer monitor and projector. (CRT, LCD, Plasma,
DLP, D-ILA etc). In order to support the emerging popularity of
24p equipment and digital display, the SDM-872p DVI output with
selectable 3:2 sequence insertion.

2.0 Overall View
Figure 2 illustrates the SDM-872p'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 Digital RGB out-
put is provided by the DVI-D 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-872p. The power supply provides a re-
gulated +5 [email protected] A power source. The SDM-872p 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 Digital RGB Video Output
The digital RGB video output signal (DVI-HDTV) is provided by
the DVI-D (female) labeled OUTPUT. The output format is auto-
matically 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.
Pushbutton Selection
The “Select” pushbutton allows the selection of different process-
ing modes, according to the input format. When the pushbutton
is depressed once, the LED indicating the currently selected pro-
cessing mode flashes red and green; when depressed again, the
alternate option LED flashes in its turn if it is available. Confirm
the selection by depressing the pushbutton again. Other pro-
cessing modes are accessed by depressing the pushbutton con-
secutively until the desired mode is reached. For processing
mode A, Band C, both LEDs need to be turned on. See the sup-
ported format table in section 5 Specification for details on
resulting outputs.
Mode A: use this mode to output 25PsF signal from a 24p or
24PsF input signal.
Direct output:
use this selection to output a signal with the same
format as the input signal.
3:2 Insert: inserts a 3:2 sequence to output a 59.94i and 60i signal.

Varicam 1:1:
use this setting to output a 24p, 25p or 30p signal
from a 60p or 59.94p signal originating from a
Panasonic varicam system.
Varicam 1:2 :
use this setting to output a 50p signal from a 60p
signal originating from a Panasonic varicam system.
4.2 Status LED
The multicolored status LED, located between the HD/SD SDI IN
and LOOP BNC connectors, is provided to identify any input
errors and the selection of the test pattern. The following lists all
possible situations.
Green: Indicates that the SDM-872p is powered and
has detected a valid input signal.
Red: Indicates an invalid input signal or simply, there
is no input signal installed.
Orange: The test pattern is selected.
