JED Microprocessors Pty. Ltd. 

JED designs and manufactures a range of small industrial and scientific computers, as well as analog and digital PC interfaces in Melbourne, Australia.

Just added to this site is the JED T460 RS232 remote controller for LCD/DLP data and video projectors. This simple unit replaces complicated IR remote controllers with a lectern, panel or wall mounted box with 4 keys and an LCD display. It is ideal for class-rooms and lecture theatres, or boardrooms and even home theatre systems. For more information, go to: Projector controllers.

Also new on this site is the AVR200 Single Board Computer, sold as a kit (featured in Silicon Chip magazine, June 2005): AVR200

We also sell the Wilke Technology "Tiny Tiger" and "BASIC Tiger" high-speed multi-tasking BASIC modules, and have developed five local boards with lots of I/O, talking to JBUS and LCD displays. As well, we offer a custom design service for Tiger and other microprocessor based boards. Call us to discuss your needs, confidentially.

Our PC540 and PC541 boards are based on the Intel 80C188EB and the NEC V51 (both PC/104 format). We also use the National NSC800 (CMOS Z80, on the STD bus), the 8051/80C51/87C51 family, the Atmel AT89C52, and have new designs using the Atmel AVR family. See the new AVR580 "Little Blue Computer".

The PC564, a quad UART board with opto-isolated RS485, on PC/104, is also available.

See our data-sheet page for data sheets on all our products and download area for the JED PROM programmer and Y2K BIOS upgrade information for PC products.

JED makes an $A300 ($A330 inc GST) PROM programmer for a PC printer port, a range of LCD TFT and EL VGA display controllers (ISA bus) and stand-alone LCD serial (RS232/RS485) terminals with keyboards.

Our JBUS I/O modules on a DIN rail give low-cost industrial I/O to any PC. (Look for the JBLOCK data on our data sheet page). We also make RS232/RS485 converters and 20mA to RS232 converters.

JED moved in November 1997 to a new office/factory at 173 Boronia Rd, Boronia. The photo above shows it among the gum trees.

JED is one of Australia's PC/104 manufacturers of CPU cards. The PC/104 format is a compact, stackable PC concept well suited to embedded, portable microcomputer applications. Boards are 3.6 by 3.8 inches.

The PC540 (based on the 80C188EB) has two serial ports (one with RS485) and 40 logic I/O lines (JBUS compatible ... see below). It has a PC BIOS, and can either run ROM-DOS (from Datalight) with FLASH memory, or can be programmed easily in C using HI-TECH's low-cost embedded Pacific-C package from a PC via a serial port.

The PC541 (based on the V51) "looks and feels" exactly like a small PC from the programmer's point of view....it has dual PC 550A UARTs (one supporting RS485), a PC LPT port, a floppy disk and an IDE hard disk interface, and also runs ROM-DOS and supports on-board read-write FLASH. This board also has 20 logic I/O lines for a JBUS interface.

As well, a number of accessory products to help designers of small and/or distributed control systems are available. These use RS485 multi-drop or a simple ribbon-cable parallel bus (called JBUS) to add analog and digital input and output to single board computers, or, in fact, any PC with a serial port or a parallel D25 printer port. These modules, called JBLOCKs, are mounted in Phoenix UEGM-MSTB cases and are 90mm square, and sit on a DIN rail at 25mm spaces, providing screw-terminal industrial I/O to the controlling microcomputer or PC. Simple driver routines in C are available.

JED makes a broad range of display controllers for our various products, or for stand-alone applications. These start with a 4-digit 17mm high LCD displays to connect to our boards (J965), or multi-drop RS485 (J969). We support RS232 or multidrop RS485 character displays (J971, a 2 line by 40 character module). The J962 is a 8 line by 40 character text and graphics LCD terminal with a QWERTY keyboard scanner built in. On the ISA bus, the AT350/351/355 series of flat panel controllers plug into any ISA-bus PC and control most (mono, passive colour, TFT colour) VGA and super-VGA LCD panels or Sharp Electroluminescent panels.

For industrial network designers, JED makes a range of line adaptors: these convert RS232 to RS485 two-line or four-line networks. Our newest one, the automatic J995X includes it's own PIC microcontroller providing an automatic "connect-to-line" function. It senses the TX data from the PC and turns the RS485 transmitter on for exactly the length of a character, saving the programmer from having to control the transmit function via the RS232 RTS line...a difficult task under some operating environments. The J990 converts RS232 to 20 mA loop.

A very popular PROM programmer (priced at $A300, $A330 inc. GST) is manufactured by JED in Australia: this connects to a PC parallel printer port, and comes complete with a printer cable, a plug-pack and powerful software allowing users to read, edit, save and write any 28-pin or 32-pin EPROM or FLASH memory device. A low-cost eraser is also available. 

JED has been designing and building small computers and controllers in Australia since 1978 in Boronia, in the City of Knox, on the edge of the Dandenong Ranges, 30km east of Melbourne. You can call and speak with the designers to discuss your specific needs or your application. JED Microprocessors was founded by, and is managed by Ed and Junette Schoell.

Here are the people who make it happen at JED, from the left: Dwain Husing (Tech.), Mik Biber (Tech. (back), Adrian Hoad (PCB designer, (back)),  Teresa Frair (Office manager), Rolf Niklaus (Production manager, (back), Lyn Schultz (PCB assembly (middle row)), Junette Schoell (Director, Co. Secretary), Edwin Schoell (Managing Director). A new arrival is Cathy Goessling, also doing board assembly.

If you would like to see a JED computer in action, have a look at an automated penguin weighing station installed in Antarctica. (A number of these are installed around the continent, and one on Phillip Island, Victoria, between the visitor grandstands.)

The JED computer is in the grey box alongside the bird crossing the scales on the way back to the colony full of krill. If you would like more information on the penguin project, and to see it in action, have a look at: Penguin report. 

All our data-sheets are available in hard-copy, or faxable form, and most on line as well, accessible on our data-sheet pages. We are using Abobe .pdf format for data-sheets: this will enable you to down-load and print high-quality originals for yourself.

You can also download software updates for the JED PROM Programmer.
