Option board I/F circuit (option)
The I/F circuit of the option board supports the following interfaces.
• RS232C (Serial I/F)
• IEEE1284 (Parallel I/F)
• Ethernet I/F (Multi-function type)
• Wi-Fi I/F
Each signal of the option board is directly connected to the CPU (U1A) and the FPGA (U5). It
is controlled by the CPU and the FPGA.
