WinSystems' Panel PC (PPC2) is a compact display subsystem that includes a flat
panel display, PC-compatible SBC with Ethernet and touch screen integrated into an
open-frame enclosure less than 3 inches thick. The combination of embedded PC functionality
and industrial-grade construction makes the unit ideal for industrial automation and control
applications with tight system integration and minimal space requirements.
The Panel PC is also perfect for networked applications since it is shipped with a wired Ethernet connection
plus expansion available for 802.11 wireless Ethernet and/or CDMA/GSM cellular modems.
The Panel PC supports operating systems such as Linux and Windows®XP Embedded, plus real time
kernels compatible with the x86 architecture.
FUNCTIONAL CAPABILITY
What is a Panel PC? - A Panel PC consists of a color TFT flat panel, Pentium-class
single board computer (SBC), and touch screen mounted in an open aluminum frame. The unit is user-configurable
to accommodate specific application design requirements.
The small size and wide operating temperature of the PPC2 makes it suitable for industrial and medical environments.
The PC/104 and PC/104-Plus connector allows industrial-grade expansion cards to be added for features such as GPS,
cellular modems, analog and digital I/O, relays, etc.
Just like a standard desktop PC, a PPC2 provides a man-machine interface. A keyboard and mouse can be used for input
plus with user-specific software, the touch panel can be included as well. This is determined by the user's application and
operating environment.
Flat Panel Display - A high-luminance, wide-viewing angle, color TFT is the foundation of the Panel PC.
It has a 12.1-inch diagonal (30.75 cm) screen that contains 1024 x 768 pixels that can display 262,144 colors.
This flat panel is ideal for factory automation use because of its high luminance of 320 cd/m2 (nits). It uses
two CCFL tubes as edge lights and are replaceable. The display supports a viewing angle of 65° horizontal and
75° vertical. This wide viewing angle permits easy planel placement with maximum operator viewing flexiblity. Also,
its contrast ratio is 550:1 thus ensuring color fidelity and superior gray scaling.
Support for other size panels are currently in development. Contact WinSystems' Application Engineering Department if you need a
different size or feature set.
Touchscreen - The Panel PC features a quick-response, resistive touchscreen, manufacturered
by Elo TouchSystems for keyboardless operation. Their touchscreen has been operationally tested to over 35 million touches
in one location, making them ideal for heavy-usage environments. It is durable since it is coated with an enhanced,
scratch-resistant hardcoat.
A touchscreen is the simplest, most direct way for a person to interact with a computer. Touchscreens eliminate the keyboard
and mouse, which may be cumbersome to use in certain application areas. Also there may be no space available for keyboard or mouse.
Plus touchscreens are rugged enough to stand up to harsh environments where keyboards and mice often get damaged.
Resistive touch screens allow all kinds of touch input devices to activate the screen, including fingers, fingernails,
styluses, and gloved hands all the while maintaining an exceptional tactile feel.
Resistive touchscreens are used in more applications than any other touch technology including hand-held computers, PDAs,
industrial equipment, point-of-sale equipment, medical equipment, office automation equipment and consumer electronics.
The Elo panel is an accurate, linear glass design which makes it inherently stable. Elo's patented AccuTouch® five-wire resistive
touchscreens have unmatched accuracy, staying linear without relying on lookup tables and curve fitting corrections. The initial setup
should last the life of the product, because only a two-point video alignment is required to normalize the touchscreen and video
coordinate systems.
Single Board Computer (SBC) - WinSystems offers different PC-compatible single board computers to serve as the
computing and display engine for the Panel PC.
WinSystems' currently offers a 1 GHz EBC-C3Plus SBC as its PC-compatible host computer for the Panel PC
(http://sbc.winsystems.com/products/EBC-C3PLUS.cfm). Based on PC/AT
architecture, it supports standard operating systems, real-time executives, utilities, and drivers such as Linux, Windows®
XP Embedded, QNX and VxWorks.
In the third quarter of 2007 WinSystems will offer the EBC-855G with either an Intel 1GHz ZC Dothan or 1.8 GHz Pentium® M
for even higher performance. The EBC-C3 and EBC-855G are similar in features and I/O mix
(http://sbc.winsystems.com/products/EBC-855.cfm). The key differences
are the processor’s manufacturer and system clock speeds, number of USB 2.0 ports, and single vs. dual 100 Mbps Ethernet support.
PC/104 Expansion Capability - Both SBCs support a PC/104 and PC/104-Plus interface connector so
that a designer can add off-the-shelf or user-designed, application specific PC/104 modules. PC/104 modules are self-stacking and plug together in a
“piggy back” configuration to serve as a mezzanine expansion bus. PC/104-Plus is the PCI bus for the I/O functions requiring higher data
transfer speeds.
PC/104 modules are very compact, measuring only 3.6 x 3.8 inches (90mm x 96mm), and are offered by WinSystems and a number of third
party companies worldwide. Module functions include serial I/O, ZigBee, Cellular modems, digital I/O, GPS, and analog I/O among other functions.
More PC/104 information including white papers, products, and specifications are on our web site at
http://pc104.winsystems.com/index_pc104.cfm.
Hard Disk Drive - One factory configuration option is a 2.5-inch hard disk drive that is mounted directly to the chassis. It is a
20GB or larger unit which is typically needed if the system is running Windows XP or if large amounts of data storage is required.
CompactFlash - WinSystems offers industrial-grade CompactFlash cards that provide operational, high capacity, solid state disk (SSD)
storage from -40° to +85°C for harsh embedded applications. The sustained data transfer rate is very fast, plus an on-card wear leveling
algorithm extends the number of write cycles to the part. These RoHS-compliant cards will fit into any computer, SBC, instrument or camera
with a CF socket. See http://www.industrialcompactflash.com for more information.
Chassis - The chassis plate is made of heavy duty aluminum alloy. It is designed to rigidly hold both the flat panel in place and
to prevent any twisting or excessive stress on the glass surface. Both the single board computer and flat panel display are mounted
directly to the same plate. The rigid plate serves as a base to hold the SBC, I/O connector plate, power terminal strip, backlight controller
and optional touchscreen controller. This assembly design is slim with a depth of less than 3 inches.
Mounting - Mounting - The Panel PC is designed to be rear mounted to a panel or placed in an instrument as a system component. Four through
holes plus four captured #4-40 press fit nuts are in the chassis for mounting flexibility.
The cut out dimensions for the panel display area is approximately 8.8 x 7.38 inches. A 0.031-inch pre-cut gasket kit is included
with each panel for use in mounting it to the designer’s final assembly.
Power - Power is accessed via an 8-pin pluggable terminal block located on the back of the Panel PC. The wiring
harness from the power supply is attached to the mating male plug which permits convenient and solid attachment of the unit to the power source
without the worry of disconnection. It will accept a range of wire from 26 to 14 AWG. All wire retention screws are located in their towers that
cannot fall out during transportation, installation and use. Wire protectors are available to protect small gauge stranded wire from screw damage.
WinSystems ships both the terminal strip and plug with each unit.
Most applications require only +5 volts and +12 volts. A negative 12 volt input is provided, but is usually used by PC/104 and PC/104-Plus
expansion boards.
Power Supply - If an external supply is needed, WinSystems offers the PS-80W-1. It is an 80-Watt universal switcher that will
accept input voltages from 85 VAC to 264 VAC (50/60Hz). It provides output voltages of +5 volts @ 12A, +12 volts @ 3A, and -12 volts @ 1A. The supply is housed in
a black anodized aluminum case. See http://www.winsystems.com/products/misc/PS-80W-2.cfm for more information.
FUNCTIONAL CAPABILITY
Operating Systems - The SBC is x86 software compatible and will run the latest versions of Windows and Linux.
It will support other operating systems such as QNX and real-time executives that require a "PC-AT" hardware environment. The Panel PC does
not ship with an operating system installed in its standard configuration from the factory.
Networking - WinSystems' SBCs supports remote booting with an onboard EPROM socket for use as a diskless
network computer. Their PC-AT compatibility supports numerous network OS and kernels.
