THE 3544 PC/104 serial interface provides four serial ports: two RS-232 and two individually configurable ports for RS-422 or RS-485.
Available from Allied Data Systems Pty Ltd , the board is capable of data rates to 460.8Kbps and uses a 16C554 UART that provides 16-byte Tx/Rx FIFOs.
Ordering options allow the choice of UARTs with larger FIFOs, support for custom baud rates and 9-bit protocols.
Sealevel's SeaCOM software utilities make installation and operation easy.
