1. Overview

1.1 Introduction

The FDVA4-DB1-M1T-WSC/FDVA4-DB1-M1R-WSC series is designed using advanced

ASIC and high-speed DSP technologies. This series employs multiplexing and

de-multiplexing techniques to transmit and receive 4 channels of video, 1 channel of

bi-directional RS232/RS422/2 wires RS485/4 wires RS485 data over a multi-mode optical

fiber in all digital signaling with no compression; making it ideal for applications where input

signal integrity and quality must be maintained and no loss should be induced. Because

this series utilizes all-digital, non-compression technology, it is able to transmit signals

without distortion; whereas the analog technology inherently noisy, low quality, long term

instability and susceptible to electromagnetically and environmental interference. This

series accepts a variety of video inputs, such as analog or digital video recorder, DVD/VCD,

digital camera, and CCTV. PAL, NTSC and SECAM standards are supported. It can support

standard RS232/RS422/2 wires RS485/4 wires RS485 pan-tilt-zoom control signaling.

Plug-and-Play design ensures ease of installation and no electrical or optical adjustment is

required. LED indicators are provided for showing operating status.

The FDVA4-DB1-M1T-WSC/FDVA4-DB1-M1R-WSC series is fully assembled using SMT

components for stability and reliability.
