PC/104 ‑ Asynchronous Serial
Item #
The 3588 PC/104 serial interface provides eight two‑wire
RS‑485 serial ports. The board includes UARTs with
128‑byte FIFOs for fast, error free communication up to
921.6K bps. To simplify RS‑485 communication, the board
used with our software driver automatically handles the
RS‑485 driver enable, allowing the RS‑485 ports to be
viewed by the operating system as standard COM ports.
Additionally, the board supports custom baud rates and
9‑bit protocols. Sealevel’s SeaCOM software drivers and
utilities make installation and operation easy.
