KEY FE ATURES: ■ 8, 4 or 2 independent asynchronous serial COM ports ■ Field selectable RS-422 and RS-485, independent for each port ■ Auto-RTS feature makes half-duplex RS-485 communications effortless ■ Speeds up to 921.6K ■ Fixed bias and jumper selectable termination provided on each transmit and receive channel simplifies cabling ■ Low power required: +5VDC at 80mA typical ■ Programmable individual non-volatile base addresses and IRQs simplifies installation ■ Operates as a standard COM port in all operating systems FAC T ORY OP T IONS: ■ 16850 UARTS with 128-byte FIFO ■ 0 to 70°C and -40 to +85°C versions available 104-COM-8S 104-COM-4S 104-COM-2S 8-, 4-, or 2-Port RS-422/485 PC/104 SERIAL COMMUNICATION The 104-COM-8S Series are eight, four, or two-port, asynchronous, serial communication boards that support both RS-485 and RS-422 communications. Ideal for POS, gaming systems, machine monitoring, military, and high-density networking applications, these boards may be installed in any system with PC/104 support. Ports are accessed via a 50-pin IDC type right angle connector. This board may be operated in two modes. In the Default Mode, the base address for the board is selected by jumpers and all of the channel addresses are sequential. Alternately, the addresses and interrupts of the individual channels may be stored in non-volatile memory on the board and loaded into programmed logic when the board is initially powered. Individual interrupts for each channel are programmed into the non-volatile memory in both modes. The boards include a convenient Auto- RTS feature, which makes half-duplex RS-485 communications effortless. The 104- COM-8S Series offer optional type 16850 UARTS with 128-byte transmit/receive FIFO buffers to protect against lost data in multi- tasking systems while maintaining 100% compatibility with all operating system COM port drivers. A jumper selection on the board permits baud rate capability up to 921.6K. ADL offers the 104-COM-8S Series in both standard and extended temperature versions ideal for outdoor applications or harsh industrial surroundings. SOF T WARE The 104-COM-8S Series is supported for use in all operating systems and include a free DOS, Linux and Windows 95/98/Me/ NT/2000/XP/2003 compatible software package. This includes sample programs and source code in "C" and Pascal for DOS, and Visual Basic, Delphi, C++ Builder, and Visual C++ for Windows. Also included is a graphical setup program in Windows. Embedded OS support includes Windows XPe and CE. An easy-to-use Windows terminal program simplifies verification of proper operation.
