Eight-Port RS-485 PC/104 Module

Targeting serial intensive embedded applications, Sealevel Systems, Inc. has introduced the SIO-104+8.485, 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 conforms strictly to PC/104 specifications and includes UARTs with 128-byte FIFOs for fast, error-free communication up to 921.6K bps. To simplify RS-485 communication, the board automatically handles the RS-485 driver enable, allowing the RS-485 ports to be viewed by the operating system as standard COM ports. Interface is accomplished via dual 40-pin header connectors. Breakout cables and other helpful accessories are available.

SIO-104+8.485 boards ship with Sealevel’s SeaCOM suite of Windows 95/98/ME/NT/2000/XP drivers. Sealevel also includes WinSSD, a full-featured application providing powerful testing and diagnostic capabilities. Use WinSSD for BERT (Bit Error Rate Testing), 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.

Standard operating temperature range is 0°C to 70°C, with an extended temperature range model offering -40°C to 85°C. Like all Sealevel I/O products, SIO-104+8.485 boards are backed by a lifetime warranty.
