SDM-272p -1

1.0 SDM-272p

1.1 Introduction

The SDM-272p is the industry’s smallest S-video encoder. This

product automatically detects 525-line and 625-line 4:2:2 signals

conforming to the SMPTE 259M-Cstandard and provides a

NTSC, PAL, PAL-M, or PAL-N S-video output signal. An internal

test pattern generator provides a color bars test signal.This

feature-packed unit delivers ease-of-use, a simplified design,

easy installation and operation.

1.2 Features

•Automatic 525-line and 625-line format input detection

•NTSC or PAL-M S-video output for 525-line input and PAL or

PAL-N S-video output for 625-line input

•Y-only (monochrome)output selection

•Output setup selection: 7.5 or 0 IRE

•Color barsgenerator

•Bi-color LED providing error status on input composite signal

•Very small packaging aluminum extruded body

2.0 Overall View

Figure 2 illustrates the SDM-272p’s major parts and their

locations. The video source is connected to the 4:2:2 input BNC

and the encoded signal is provided by the S-video output. Error

status is provided by the status LED and mode settings are

configured by two 3-position slide switches. Finally, the power

source is connected to the power connector.

3.0 Installation

3.1 Power Supply

The power supplies LKS-WSA and LKS-WSE, for 110 V and 220

Voperation respectively, are used to power the SDM-272p.

Each power supply provides a regulated +5 VDC@750 mA

power source. The SDM-272p employs a mini XLR-3 connector

for its power needs. Figure 3 provides a detailed pinout of the

male connector.

3.2 4:2:2 Input

Connect a 4:2:2 serial digital signal to the BNC labeled 4:2:2 IN.

The 4:2:2 input signal must conform to the SMPTE 259M-C

standard.

3.3 S-Video Output

A S-video signal conforming to the SMPTE 170M or ITU (CCIR)

624-4 standard is provided by the S-VIDEO OUTPUT connector.

Figure 4 provides the S-video connector pinout.

Output setup and format switch (SW1)

7.5 IRE: To add a 7.5 IRE setup to the output NTSC S-video

signal, set SW2 to this position. There is no setup

for PAL, PAL-M, and PAL-N output signals.

0 IRE: For no setup on the output S-video signal, set SW1

to this position.

Alt. Out:To enable PAL-M and PAL-N outputs during 525-line

and 625-line input formats respectively, set SW1to

this position. Refer to Table 1 for the output format

provided during this setting.

Normal, Y-only, and test pattern switch (SW2)

Normal:For normal operation, set SW2to this position.

Y-Only:Setting SW2to this position providesa monochrome

output signal by forcing the output chroma to 0.

Test: Set SW2to Test in order to enable the test pattern

generator. Make sure a valid 4:2:2 input signal is

installed. NTSC and PAL-Moutputs produce a 75%

color barssignal whereas PAL and PAL-Noutputs

produce a 75% color barswith 100% white bar

signal.

4.2 Status LED

The bi-colored status LED, located next to the S-video output

cable, is provided to identify any input errors and the selection of

the test pattern. The following lists all possible situations.

Green: Indicates the SDM-272p is powered and has

detected a valid 4:2:2 serial digital signal.

Red: Indicates an error with the input signal has been

detected or simply, there is no input signal installed.

Yellow: The test pattern is selected.

If, during a test pattern selection, an error is detected with

the input signal, the status LED will remain red.
