DESCRIPTION
All FAD-4 operations are performed via the serial interface, through the use of LESIP Master/Slave serial
interface protocol . The communication standards and timing are described in the LESIP manual. The file types
specific to FAD-4 will be described here. The FAD-4 is always a slave. In principle a number of FAD`s
may be connected in a network microprocessor controlled device.
The communication buffer size is 13 bytes max for Transmitter and Receiver (Half duplex).
Detailed description of the file types and sequences is given in the following pages .
