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.

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.
