MBC-3200 FM Multiplex Broadcasting DARC Encoder

mbc3200

The MBC-3200 is a DARC encoder with modulation function developed for Chinese traffic congestion information system(DARC-RTIC).  This unit simultaneously encodes digital traffic congestion information which is sent from traffic information center via WAN into analog signal by DARC-RTIC method. The output signal is input into FM multiplex broadcasting system, used for providing traffic congestion information for large area to drivers by using FM Broadcasting .

FEATURES

This unit equips DARC method data encode modulation function, instantaneously encodes and outputs data which is sent to this unit into FM multiplex signal.
This unit equips TCP/IP, Web Server, UDP/IP, SMTP, Telnet, etc. as standard interface for network.
The below modules are available as option.
1. Stereo Modulator Option (for testing) 2. USB connector
