General Overview - Monroe Electronics R194 Instruction Manual

General Overview

Description
The R194 (R194P supports PAL television display systems) is an eight-channel
on-screen composite videotext character generator that can overlay crawl
characters onto program video during EAS alerts. Alert audio also replaces
program audio for each channel. Video loop-thru connections are all BNC type.
Audio loop-thru connections are all pluggable screw terminals. Control is by
standard RS-232 signaling using DB9 type connectors. Up to 32 R194's can be
daisy-chained together to allow EAS service to as many as 255 individual analog
channels from a single Monroe EAS controller.
Application
During EAS alerts, data, audio trigger, and audio inputs received from the R189
One-Net, EAS Encoder/Decoder, are used to automatically create a videotext
crawl message and override audio signals. When activated, the EAS videotext and
audio signals are passed to the system's distribution equipment. At the conclusion
of an alert, the unit returns to normal function.
