Mosaic portable handheld instrument controller with HMI

The Mosaic Handheld^TM - an instrument controller with a graphical user interface for data acquisition and sensor calibration - makes it easy for you to design a custom portable instrument. It integrates a graphics display, keypad with customizable overlay, processor, memory, analog and digital I/O, serial communications, an expansion I/O bus, rechargeable batteries, power conditioning and battery charger circuitry in a rugged handheld enclosure. A DB-25 connector at the bottom of the instrument allows you to connect external signals to the instrument. The built-in Personality Board makes it easy to route internal and external I/O and data signals inside the instrument, and includes a prototyping area to simplify the addition of custom circuitry. You can plug in up to 4 Wildcard I/O cards inside the instrument to customize the Handheld for your application. The rugged plastic enclosure is small enough to fit comfortably in your hand but large enough to hold your custom circuitry, sensors and actuators.

When designing a new portable device, the job of integrating the battery charger, switching power supplies, user interface, embedded computer and board-to-board interconnects in a compact enclosure consumes a huge amount of engineering effort. The Mosaic Handheld solves all these problems for you, providing an elegant platform that lets you concentrate on the unique aspects of your application. By starting with this highly integrated operator interface system, you'll get to market faster.

The Mosaic Handheld is ideal for prototyping and manufacturing portable instruments for data logging, inventory management, data acquisition, sensor calibration, industrial control, and scientific instrumentation.

A Powerful Controller and Lots of I/O

The Processor Board inside the Handheld hosts a 16 MHz Motorola 68HC11F1 microprocessor, 512K Flash and 128K RAM (expandable to 1 MB Flash and 512K RAM), and 320 bytes of EEPROM. On-board I/O includes 8 digital I/O lines with counter/timer capabilities, 8 analog inputs, a fast synchronous SPI serial interface, and dual RS232/485 ports. An optional real-time clock tracks the calendar and time of day and battery backs the 128K RAM.

To communicate with your Handheld via USB, add USB adapter and cable (Part No. USB-QCC)

The processor is easily programmable in C, Forth or Assembly using any PC. Built-in programming tools include an interactive debugger, a multitasking executive, comprehensive device-driver libraries, and a GUI (Graphical User Interface) toolkit.

Friendly Graphical User Interface

The Handheld features a keypad and 128 x 128 pixel liquid crystal display for showing text and graphical images. The high-contrast 3.4" diagonal display and 4 column by 8 row keypad are controlled by means of a precoded GUI Toolkit that makes it easy to program an intuitive user interface using menus and bitmapped graphics. The software draws the screen graphics, responds to keypad presses, provides audible keypress feedback, and even implements front panel control of the backlight and display contrast.

Put Your Instrument Online

Web-enable your Handheld with the EtherSmart Wildcard, or WiFi Wildcard . Your application program can send emails to alert other computers on the network when significant events occur. You can even "browse into" your instrument controller using a browser running on an online PC to monitor the status of your instrument, diagnose problems or update its software.

Easy To Customize

The Personality Board allows you to filter and protect the I/O lines and to route them to a customizable DB25 connector on the bottom of the enclosure. The Personality Board also hosts up to 4 I/O Wildcards that stack onto 24-pin Wildcard connectors in the Handheld. Wildcards implement a wide variety of communications, data acquisition and control capabilities. In the Wildcards section of this catalog you can select the Wildcards that meet your needs to configure a cost-effective customized instrument for your application.

A convenient prototyping area allows you to integrate application-specific circuitry including sensors and actuators.

Battery Power for Portability

The Handheld can operate for up to 10 hours on its six rechargeable 2 amp-hour nickel-metal hydride (NiMH) batteries. The Power Board contains circuitry that recharges the batteries in only two hours. The battery pack may be charged overnight or while the instrument is in use. For non-battery applications, you can power the instrument with 15 to 26 VDC via the power jack or through the DB25 connector on the bottom of the unit.

The Power Board also implements power control circuitry that responds to a dedicated on/off key on the front panel keypad.

Fast Time to Market

For a fast start, to rapidly prototype using the Mosaic Handheld, order a Mosaic Handheld Starter Kit (Part No. HH11SK), which includes everything you need to develop a battery operated handheld instrument: the Mosaic Handheld (p/n HH11) with options: -MM, -RB,- BT, -PB PS-HH-24V, board interconnect cable to facilitate hardware development, serial cable, and a full documentation package.

To communicate with the Handheld via USB, order the Starter Kit with a USB option (Part No. HH11SK-USB).
