low cost, versatile instrument controller
with expandable I/O
The QScreen Controller™ combines a C-programmable single-board computer (SBC) with a touchscreen-operated graphical user interface. Designed as a fully-functional, compact industrial PC powered by an HC11 Motorola microprocessor, this low-cost embedded computer is ideal for OEM applications where installation space is critical, such as embedded systems, scientific instruments, robotics, and portable data acquisition. The QScreen can be commanded remotely from a PC or used stand-alone providing real-time control of dozens of analog and digital I/O lines.
Use it as a customizable HMI/MMI or industrial operator interface for SCADA, process control, or automation -- anywhere you need an embedded GUI interface, programmable controller, or stand-alone operator interface terminal.
State-of-the-Art Operator Interface Panel
Today's tech-savvy customers demand sophisticated yet easy-to-use front panel user interfaces for embedded control, also referred to as human-machine interfaces HMI or man-machine interfaces MMI. Mosaic provides software tools to help you quickly develop menu-based man-machine graphical interfaces that respond to the user's touch.
The QScreen Controller sports a touchscreen-operated graphical user interface on a high-contrast 128x240 pixel display with a 5x4 touchscreen overlay. It comes complete with object-oriented menuing software that makes it easy to control your application using buttons, menus, graphs, and bitmapped pictures.
Display your own custom graphics on a bright white-on-blue cold-cathode fluorescent (CCFL) backlit screen. You can create hundreds of sophisticated screens for this low-cost single board computer, including your company logo, system diagrams, and icon-based control panels using most Windows paint programs, such as PC Paintbrush. Startup screens and your application program will execute automatically on power-up.
Embedded web server
Web-enable your QScreen 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.
Plenty of Memory
Choose among many options: from 512K Flash and 512K RAM for a standard configuration up to 1M Flash with the expanded memory option. For those really extensive applications that require lots of memory or removable data storage, add the Compact Flash Wildcard to provide additional mass memory.
Real time multitasking operating system
The QScreen Controller includes a powerful microcontroller you can program either in Control C or QED-Forth. It comes loaded with a real-time multitasking operating system and hundreds of precoded device drivers. Programming is a snap using the interactive debugger and multitasking executive. Program in ANSI C by compiling your application on your PC and downloading the code to the QScreen Controller where it is automatically executed. The real-time operating system in onboard FLASH memory manages all required initializations and autostarts your application code.
Expand and Customize I/O
Control dozens of analog and digital I/O lines in real time. The QScreen Controller commands eight 8-bit A/D lines, 8 digital I/O lines including timer-controlled and PWM channels, and two RS232/485 ports. Pre-coded I/O drivers are provided for all I/O, and make it easy to do data acquisition, pulse width modulation, motor control, frequency measurement, data analysis, analog control, PID control, and communications.
Need even more I/O? The QScreen Controller hosts Mosaic's Wildcards™, small stackable I/O modules for sophisticated and dedicated I/O. Stack up to seven Wildcards for: 16- or 24-bit resolution programmable gain A/D; 12-bit D/A; compact flash mass memory; opto-isolated AC or DC solid state relays; configurable digital I/O; additional RS232, RS422 or RS485; or high-voltage, high-current DC inputs and outputs. To communicate with the QScreen via USB, add a USB to RS232 adapter (Part No. ADAP-USBRS).
Need Protection from Aggressive Environment?
Consider our Environmental Gasket and Screen Protector to provide a tight, chemically resistant seal between your touchscreen and bezel and to prevent scratching & infiltration of dust or liquids.
