JK SYSTEM

JK System 89-0055 Rack Mount - TCP/IP, DOS & Flash File System Simple Type: Rack Mount Packaged in a slim 1RU rack mount enclosure, the LogicFlex-EPX uses 2-part detachable screw terminals to easily integrate existing equipment without costly interface boards, thus eliminating the wiring problems commonly associated with board level product integration. Standard I/O features incorporate 16 optically-isolated inputs, 16 relay outputs, 2 serial ports, and onboard Ethernet, which connects directly to 10BASE-T networks via RJ45. A back lit LCD, 6 push buttons, flexible storage options, expansion bus for peripheral boards, and optional 8-channel A/D, all add versatility to the LogicFlex-EPX system. The powerful Intel 386Ex processor, NE2000 compatible Ethernet, preinstalled TCP/IP Web server software and DOS operating system allow design and debugging in a familiar environment. The serial ports, counter/timers, and interrupt controller are fully compatible with the IBM PC at both the hardware and software levels. Additional features include a watchdog timer, RS485 serial port capability, hardware clock/calendar and high-efficiency switching input voltage regulator. Download the datasheet (PDF)

JK SYSTEM

Jk System 84-0120 System- 40MHz 186 Compatible Processor. Simple Type: System On a form factor slightly larger than a credit card, we’ve implemented a 40MHz x86 DOS computer. The system features ½ megabyte each of RAM and Flash memory, two serial ports, battery-backed clock calendar, 10Base-T Ethernet and a socket for optional M-Systems DiskOnChip products. Also included on the board are 16 bits of digital I/O, a watchdog timer, RS-485 and TTL serial port I/O, and LCD and keypad drivers. The picoFlash controller comes with preloaded DOS and all the utilities you need to start development. Our low-cost development kit contains a full copy of Borland C/C++, the WatTCP TCP/IP stack, and source code for a number of TCP/IP clients and servers including HTTP, TFTP, FTP, Telnet and PPP.

84-0023

JK SYSTEM

Jk System 84-0023 I/O expansion board - 4 or 8 Channel 12 Bit A/D Simple Type: I/O Expansion capability (for GPS or modem) and isolated high current drivers to many JK microsystems single board computers. Available in several configurations, each Multi-I/O board can add up to 8 channels of 12 bit A/D, 4 channels of 12 bit D/A, 8 relay output drivers and 2 UARTs. If more I/O is required, several boards can be added to the system using 10 pin IDC style ribbon cables. A driver library with functions callable from C or QuickBASIC and example programs are available to eliminate the hassle of programming devices on a serial bus. Download the datasheet (PDF)

84-0011

JK SYSTEM

JK System 84-0011 processor chip - 25Mhz Intel 386Ex Processor Simple Type: Processor The Flashlite 386Ex is a single board computer based on the Intel 386Ex processor chip. The 386Ex is a highperformance, 32-bit, single-chip microcomputer that is capable of protected-mode operation and includes an extensive array of integrated peripherals. The Flashlite 386Ex, like all members of the JK microsystems family of controllers, comes pre-loaded with DOS and utilities so that you can begin development right away. By connecting one of the Flashlite 386Ex serial ports to your PC and running a telecommunications program, you can immediately upload and execute programs compiled for a PC.

84-0007

JK SYSTEM

Jk System 84-0007 Converter board - 8 Channel, 12 Bit A/D Converter. Simple Type: Converter This 12-bit A/D converter board is based on the Maxim MAX197 chip. The board features software-selectable input ranges of ±10V, ±5V, 0V to 10V, and 0V to 5V. Conversion time is 6µs. The basic A/D Converter board has ±16.5V input protection and unbalanced inputs. An enhanced version of the A/D board is also available. This board can be upgraded on a per-channel basis to provide balanced inputs with ±200V common mode rejection and ±500V common-mode and differential protection. The board also has screw terminal input connections and ±15V available for external signal conditioning.
