104-COM232-8 104-COM232-4 104-COM232-2 PC/104 8-, 4-, or 2-Port RS-232 SERIAL COMMUNICATION K E Y F E AT U R E S : FAC T ORY OP T IONS: ■ 8, 4 or 2 RS-232 asynchronous serial COM ports ■ 0 to 70°C and -40 to +85°C versions available ■ Speeds up to 921.6K with 64-byte FIFO ■ 128-byte FIFO ■ Programmable IRQ sharing simplifies system design and installation ■ Low power required: +5VDC at 80mA typical ■ Operates as a standard COM port in all operating systems The 104-COM232-8 series are eight, four, or two-port asynchronous, RS-232 serial communication boards. The boards are feature-rich and allow for the connection of multiple serial devices—ideal for a variety of applications such as POS, barcode readers, modems, machine monitoring and control, military, high-density networking applications or any other application requiring the connection of RS-232 serial devices to a PC/104 compatible system. Ports are accessed via two 40-pin IDC type right angle header connectors for the boards optional breakout cable. The 104-COM232-8 series were designed using type 16780 UARTS and include 64byte transmit/receive FIFO buffers to protect against lost data in multi-tasking systems while maintaining 100% compatibility with all operating system COM port drivers. ADL offers the 104-COM232-8 series in both standard and extended temperature versions ideal for outdoor applications or harsh industrial surroundings. Ordering options include UARTs with larger FIFOs, support for custom baud rates, vertical I/O pins, and custom cabling. S O F T WA R E The 104-COM232-8 series are 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.
