These modules provide eight asynchronous serial communication ports from a single IP carrier slot. Software-con figuration helps you quickly set baud rates, character-sizes, stop bits, and parity. Signal support for RTS/CTS handshaking is also included.
For more e fficient data processing, each serial port is equipped with 64-character FIFO buff ers on the transmit and receive lines.
The data ports generate individually controlled transmit, receive, line status, and data set interrupts. Since unique interrupt vectors may be assigned to each port, it is easy for you to identify and locate the interrupt source. Also, a priority shifting scheme prevents continuous interrupts from one port from blocking interrupts from another.
Features
- Eight RS232E ports
- 64-byte transmit FIFO bu ffers
- 64-byte receive FIFO bu ffers
- Interrupts with unique vectors for each port
- Programmable baud rate (up to 230Kbps)
- Individual handshake lines (RTS, CTS) on each channel
- Line-break and false start-bit detection
- Industry-standard 16C654 family UART includes software-compatible 16C450 mode
- High-density design lowers per-port costs and saves IP carrier card slots for other functions.
- 64-byte FIFO buff ers minimize CPU interaction for improved system performance.
- Each serial channel provides handshake support to simplify interfacing with modems.
