Product short description:
  • Four asynchronous EIA/TIA-422B (EIA-485) serial ports
  • FIFO buffers (16, 64, or 128-byte)
  • Interrupt support
  • Programmable baud rate (up to 512Kbps)

Not recommended for new designs. Limited availability - please contact sales department.

[DISPLAY_ULTIMATE_PLUS]

These modules provide an asynchronous serial communication interface for your system. They have four asynchronous, full-duplex RS422B serial ports. Since the transceivers are compatible with the RS485 standard, you can also use a full-duplex RS485 interface for multiple driver support. However, for true half duplex RS485 operation, use the IP502.

Software-configuration quickly sets the baud rate, character-size, stop bits, and parity.

For more efficient data processing, each serial port is equipped with 16, 64 or 128-character FIFO buffers on the transmit and receive lines.

Specifications

RS422B Serial Ports

Configuration: Four independent, non-isolated RS422B serial ports with a common single return connection.
Data rate: Programmable up to 512K bits/second using internal baud rate generator. Consult factory for custom baud rates up to 1M baud.
Interface: Asynchronous serial only.
Character size: 5 to 8 bits, software-programmable.
Parity: Odd, even, or no parity; software-programmable.
Stop bits: 1, 1-1/2, or 2 bits; software-programmable.
Interrupts: Receiver line status (overrun error, parity error, framing error, or break interrupt); received data available (FIFO level reached) or character time-out; transmitter holding register empty; or modem status (CTS). Multiple ports share the IntReq0 line according to a shifting priority scheme based on the last interrupting port serviced.
