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.
