Targeting serial intensive embedded applications, the SIO-104+8.485 is an eight-port PC/104 RS-485 module. Designed to meet the core needs of PC/104 applications requiring high reliability, small size, and long-term availability, the board is perfect for a wide variety of military and commercial applications.

The SIO-104+8.485 strictly conforms to PC/104 specifications and includes UARTs with 128-byte FIFOs for fast, error-free communication up to 921.6 kbps. To simplify RS-485 communication, the board automatically handles the RS-485 driver enable, allowing the RS­485 ports to be viewed by the operating system as standard COM ports. The interface is achieved via dual 40-pin header connectors. Breakout cables and other helpful accessories are available.

SIO-104+8.485 boards ship with the SeaCOM suite of Windows 95/98/ME/NT/2000/XP drivers. Also included is WinSSD,            which is a full-featured application that provides powerful testing and diagnostic capabilities. Use WinSSD for bit-error rate testing (BERT), throughput monitoring, loopback tests, and transmit test pattern messages. In addition to Windows drivers and utilities, SeaCOM includes application notes and technical details to simplify installations in LINUX, QNX, and DOS.

SIO-104+8.485 modules (part number 3588) cost $219 each in low-volume quantities.
