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.
