Targeted for designs requiring a large number of I/O lines or user designed logic, this controller is an ideal platform for bridging existing equipment to Ethernet networks. The LogicFlex features a 386 DOS computer, 10BASE-T Ethernet, and an in-circuit-programmable Xilinx CPLD. The DOS operating system allows for design and debugging in a familiar environment. PC compatible serial ports and bit I/O make system integration a snap. Peripheral boards are also available to add serial ports, A/D, D/A, high current drivers, relays and isolated I/O for many data acquisition and control applications. Based on the Intel 386Ex microprocessor, the LogicFlex includes an extensive array of integrated peripherals. Onboard Ethernet allows direct connection to 10BASE-T networks. The serial ports, counter/timers, and interrupt controller are fully compatible with the IBM PC at both the hardware and software levels. With additional features such as the watchdog timer, RS-485 serial port capability, hardware clock/calendar, flexible storage options, and aggressive pricing, the LogicFlex is also a great choice for new embedded designs requiring network connectivity. The LogicFlex Development Kit (99-0051) includes a LogicFlex single board computer, Programming Cable, Connector Kit, Ethernet Cables, 110 VAC Adapter, Setup guide, Schematic, and CD with Borland C/C++ V4.52 Compiler, utilities, sample programs and documentation. (220Vin to 110V transformer (70-0006) available.) Also included are sample programs and source code for the TCP/IP stack and web server that can be compiled with the Borland C/C++ package.
