Targeting serial intensive embedded applications, Sealevel Systems, Inc. has introduced the SIO-104+8.485, an eight-port PC/104 RS-485 module.
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 RS485 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. The module ships with Sealevel Systems' SeaCOM suite of Windows 95/98/ME/NT/2000/XP drivers. Also included is WinSSD, a full-featured application providing powerful testing and diagnostic capabilities.
WinSSD is used 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.
The SIO-104+8.485 module is $219 each in low volume quantities.
