Global Positioning System (GPS) ReceiversThe MICRODESIGNS series of GPS Receivers are designed around OEM GPS engines manufactured by Magellan Navigation. Formerly marketed under the Ashtech® and Magellan brands, these GPS engines are the core of our family of products that may be used to evaluate GPS for your application or as end-user products in their own right.
Magellan Navigation AC12 GPS engine, the GPS-103 provides a rugged enclosure, an RS-232 interface, status display and power conditioning for demanding mobile environments. Manufactured for Magellan Navigation by MICRODESIGNS, AC12 Sensor details and a PDF-format datasheet may be found here.
Panasonic Thermoluminescent Dosimetry (TLD) Reader AccessoriesThe MICRODESIGNS series of Glow-Curve Interfaces acquire detailed information about the radiation dose read from a Thermoluminescent Dosimetery badge by a Panasonic TLD badge reader. The GCI digitizes phosphor glow-curve and timing data and saves the reader's measurement string for analysis and long-term storage by a host computer. Programmed using English-like command mnemonics, our GCIs are supported by third-party software vendors, managing glow-curve data as port of a complete personnel dose data managment package.
The GCI/2 operates with Panasonic UD-710A and UD-716AGL automatic TLD readers along with the UD-702E, UD-705 and UD-706A manual readers and is our most economical solution to glow-curve acquisition requirements. Functionally similar to the GCI/1, the GCI/2 is a compact single-board GCI which is installed in an ISA/EISA-compatible PC/AT, 386, 486, or Pentium personal computer host. A detached indicator pod provides GCI status information. Information is transferred between the GCI/2 and the host via the host's internal ISA backplane bus. The GCI/2 is suitable for PCs running Windows 95/98/ME or MS-DOS only; use a GCI/3 for PCs operating under Windows NT, Windows 2000 or Windows XP.
Functionally identical to the GCI/2, the GCI/3 is a glow-curve capture device in a small stand-alone desktop cabinet which communicates to a host computer via an RS-232C serial interface. Because it is self-contained and uses the industry-standard RS-232C serial interface, the GCI/3 can be easily interfaced to a wide array of computers and operating systems. Dosimetry management systems which use PCs, workstations, or notebook computers as hosts are candidates for the GCI/3.
The GCI/3 now supports the Panasonic UD-7900 Reader; contact MICRODESIGNS for details.
The TCA/1 is an accessory fixture that allows direct measurement of the badge heating cycle in a Panasonic TLD reader. When used with a MICRODESIGNS or Panasonic glow-curve interface, the digitized thermal curve generated by the TCA/1 may be observed on a host computer's graphics display, analyzed and stored for later reference. The TCA/1 displays the base and peak temperatures of an observed heating cycle on a four-line alpha-numeric LCD display, allowing stand-alone use.
The TCA/1 now supports the Panasonic UD-7900 Reader; contact MICRODESIGNS for details.
The LMP-7900 Lamp Bias Control is a reader accessory that manages the heating lamp bias current in Panasonic’s flagship UD-7900 TLD reader. Requiring only screwdrivers for installation, the LMP-7900 allows manual adjustment of the bias current and also permits measurement of the lamp voltage and current waveforms by service technicians.
The Panasonic UD-7900 TLD reader uses an advanced computer-controlled power supply to operate the heating lamp, which allows the UD-7900 to operate in UD-710A heating mode, UD-716AGL heating mode, or anywhere in between. However, an unfortunate side effect of the new technology is the loss of the lamp bias constant-current feature provided in those older Panasonic readers.
Installed between the lamp power supply and the UD-7900’s heating lamp, the LMP-7900 restores the missing lamp bias constant-current feature. The LMP-7900’s operation is simple: if the lamp voltage supplied by the reader is greater than 2.5 Volts (lamp “on”), then the LMP-7900 applies the full voltage to the lamp; if the lamp voltage is less than 2.5 Volts (lamp “off”), then the LMP-7900 switches to bias constant-current mode. The LMP-7900’s bias current level is set manually with an internal screwdriver control — similar to the adjustment in the UD-710A — and is factory-preset to a value of 2.0 Amps.
Industrial Single Board Computer Expansion (SBX) BoardsIntel developed the SBX Multimodule concept in the early 1980s as a method for easily expanding the on-board resources of industrial single-board computers. Intel allowed SBX to be an open architecture standard and encouraged their customers and competitors to design specialty I/O boards. Eventually becoming IEEE Standard 959, the SBX standard defines two PC board sizes: the "single wide" measuring 2.85 x 3.70 inches and the "double wide" measuring 2.85 x 7.50 inches; both sizes attach to the host board using a special locking connector and one or more nylon spacers with screws. Although not as widely used as they were in the 1980s and early 1990s, SBX modules continue to be used today in many legacy computer systems.
An SBX board providing two independent RS-232C or RS-422A/449 serial ports with individually programmable baud rates; a battery-maintained clock/calendar with programmable periodic, time-of-day alarm and power fail interrupts; and 8K, 32K or 128K bytes of battery-maintained CMOS RAM. Available in mixed TTL/MOS/CMOS logic or all-CMOS for low operating power applications. Double-wide SBX module.
The MICRODESIGNS uDX-241 Clock and Quad Serial Multimodule contains circuitry for a battery-maintained real-time Clock/Calendar and four independent RS-232C or RS-422A/485 multi-protocol serial I/O channels on a dual-width SBX expansion board. Each channel may be individually configured for synchronous or asynchronous operation, baud rate, and RS-232C or RS-422A electrical interface. The uDX-241 attaches directly to any SBX-compatible host board which supports a double-wide module, and is available in mixed TTL/MOS/CMOS logic or all-CMOS for low operating power applications.
An SBX board providing four independent RS-232C or RS-422A/449 serial ports with individually programmable baud rates. Available in mixed TTL/MOS/CMOS logic or all-CMOS for low operating power applications. Your choice of 8080/85 or 8086/88 software drivers is included. Double-wide SBX module.
An SBX IEEE-488 (GPIB, HPIB) interface providing talker, listener and controller functions using the industry-standard Texas Instruments TMS-9914A GPIB controller chip set. Provides full GPIB capability, including proper DMA operation. A GPIB-compatible flat cable with metric hardware and your choice of 8080/85 or 8086/88 software driver is included. Single-wide SBX module.
A fully buffered 48-line parallel I/O SBX board which provides twice the capacity of the industry-standard SBX-350 while maintaining connector and functional compatibility. The uDX-548 makes parallel printer interfacing particularly easy through pre-wired sockets and a simple interconnecting cable. Double-wide SBX module.
The MICRODESIGNS uDX-549 provides 48 bit-programmable lines of buffered TTL-compatible parallel I/O on a single-wide SBX board. Each line is individually software programmable as an input or output, so the user is not required to configure lines in groups of 4 or 8 input/outputs. Each line is terminated with a 1.0 KOhm pull-up resistor, and, when configure as an output, is an open-collector TTL driver capable of sinking 24 milliamperes. The uDX-549's two 50-pin I/O connectors are compatible with OPTO-22-type industrial interface racks and modules. To ease software programming, previously written output values can be read back. The uDX-549 improves on competitive SBX modules by offering twice as many parallel lines, I/O direction bit-programmability, and high current TTL buffering while retaining a single-wide SBX board form factor.
