Model DCFCTBD-IP
General
The DCFCTBD-IP combines the characteristics of a DCFCTBD with Serial to
Ethernet conversion capabilities. This allows serial devices to communicate over an
Ethernet network and provides audio decoding of digitized audio sent over the
network.
The converter is configured with its own fixed IP address and port number. When
packets of data are received over the Ethernet port that are addressed to the board’s IP
and port number, they are converted to serial data and sent out over the serial port.
Likewise, any data coming into the serial port is converted to TCP/IP data packets
and sent out over the Ethernet port to the server’s IP address. The unit also contains a
digital to analog converter. This allows specially configured incoming data packets to
be converted to audio, which is then filtered and sent out over a 600 ohm audio port.
