Spyder: Uart Over Narrow Band Powerline Communication Modem

These Spyder: UART Over Narrow Band Powerline Communication Modem is designed to transparently move serial data over the power line network at a speed of 2kbps, and achieves the target of replacing serial cables by the ubiquitous power line network.
On the Spyder motherboard, there is a 20-pin receptacle. Users can choose different daughter boards, such as RS232, RS485, USB or Ethernet, based on the interface needs. The motherboard also support DIP by optional pins that can be used to directly plug to user's board without doing screwing.

Spyder: UART Over Narrow Band Powerline Communication Modem has built-in packet-level repeater function. This feature can greatly extend the coverage of the power line communication. Spyder has both physical and logic addresses. In a network, both physical and logic addresses can be used to address different nodes in the network.
