Protocol
To make the relay PCB do things, you need to send things over the SPI bus to the PCB.
The general overview of the protocol is here.
The specific commands for the relay PCB are explained on the page about the spi_dio board, as the two boards share the same protocol: spi_dio_protocol .
For arduino, a sample PDE is available, called ardemo_lcd.pde, also at BitWizard software download directory .
This is a demo to send things using SPI to the lcd board. The SPI routines there are applicable for the dio and relay boards as well.
