4.4 SPI interface

DSM setup parameters are changed via an SPI (Serial Peripheral Interface) port. This port uses a 10-pin IDC header, and connects to a USB port on your PC. The recommended method of connecting the SPI port to the PC is by using parameter setup cable CBL055-501. The PC requires a standard USB port.
