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 peripheral devices is likely to result in
interference with radio and television reception. This
equipment has been tested and complies with the limits
in accordance with the specifications in:

FCC Part 15, Subpart B

Guide to Installation and Operation

1.0 ADC-191p

1.1 Introduction

The ADC-191p is the industry’s smallest component
analog video to 4:2:2 serial digital video ADC. This
product automatically detects 525-line and 625-line CAV
signals and provides a 4:2:2 serial digital output signal
conforming to the SMPTE 259M-C standard. Both
SMPTE/EBU and Betacam CAV sources are supported.
In addition, this feature-packed unit delivers ease-of-use,
a simplified design, easy installation and operation.

2.0 Physical Layout

Figure 2 illustrates the ADC-191p’s major parts and their
locations. SMPTE/EBU or Betacam sources are
connected to the CAV input BNCs and the 4:2:2 serial
digital output is provided by the 4:2:2 output BNC. 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 V operation respectively, are used to power the
ADC-191p. Each power supply provides a regulated +5
VDC@750 mA power source. The ADC-191p employs a
mini XLR-3 connector for its power needs. Figure 3
provides a detailed pinout of the male connector.

Guide to Installation and Operation

3.2 CAV Inputs

The CAV inputs consist of green, blue, and red color
coded male BNC connectors. Male connectors are
provided so as to connect the ADC-191p directly to
source equipment. The supported CAV input standards
are SMPTE/EBU and Betacam. The Betacam standard
can be set with or without setup. The input Y/B-Y/R-Y
signals are to be connected to the green, blue, and red
BNCs respectively

Refer to section 4.0, Operation in order to select the
desired input CAV standard.
.

3.3 4:2:2 Output

The 4:2:2 serial digital output signal is provided by the
BNC labeled 4:2:2 OUT. The 4:2:2 output signal
conforms to the SMPTE 259M-C standard..

4.0 Operation

4.1 Switch Settings

Figure 4 shows the slide switch locations and functions.

Figure 4: ADC-191p switch settings
Input format switch (SW1)

SMPTE: For SMPTE/EBU CAV inputs, set SW1 to

this position. The Y/B-Y/R-Y inputs are to
be connected to the green, blue, and red
connectors respectively.

BETA 0: For BETA sources with 0 IRE setup, set

SW1 to this position.

BETA 7.5: For BETA sources with 7.5 IRE setup, set

SW1 to this position.

Input stability switch (SW2)

VTR: Set SW2 to VTR if the CAV inputs are VTR-

type or non-time based corrected signals.

Studio: For stable studio CAV sources, set SW2 to

this position.

4.2 Status LED

The bi-colored status LED is provided to identify any
input errors. The following lists the possible situations.

Green: Indicates the ADC-191p is powered and has

detected a valid CAV input signal.

Red: Indicates an error with the input signal has

been detected or simply, there is no input
signal installed.
