Description
The DCB1M Evaluation Board contains all the required firmware for operation as a DC power line transceiver.
The board has a line protection network and BPF filter required for the DCB1M IC operation.
A switching power supply provides the 3.3V required for the board operation from 10V to 36V DC power line.
Operation
At the transmitter side, the external host inputs messages to the DCB1M IC via J1 HDI pin for asynchronous UART/DMX512 RDM or synchronous SPI/I2C bit stream. The message is constructed into packets, protected against errors, modulated, and conducted over the DC power line.
At the receiver side, the received phase-modulated signal from the DC line
is decoded back into a bit stream message. The asynchronous or synchronous (UART/SPI/DMX512/RDM/I2C) message output to the external host via J1 HDO.
