Principle Description

Interfaces between the PC carry board and IOBOX: 1 USB port, 1 network port.
3.2.9 IO module
The IO module consists of IO connecting board, IO adapter board, and IO interface board.
The connection relation between these boards is shown as follows:
1. One end of the IO connecting board is connected to the DSP board, and the other end is
connected to the IO adapter board; the standard 40PIN IDE HDD interface and 4PIN
power interface are provided, and the power socket for HDD cooling fan is reserved.
2. One end of the IO adapter board is connected to the IO connecting board, and the other
end is connected to the IO interface board; the adapter board serves as an extension
board.
3. The IO interface board is connected to the IO adapter board, and provides IO interfaces
and the power of the system; the IO interfaces are divided into internal IO (invisible for
the user) and external IO (visible for the user).
The block diagram of the IO module is shown as follows:
