Boards embed four or eight switchable serial ports
The 104-COM-8S and 104-COM-4S are the latest additions to the line of PC/104 boards from Acces I/O Products.
Four Es a jolly good acquisition system
The Model E4-DAS takes its name from being an easy to use, Ethernet enabled, embedded and environmentally adaptable PC/104-based data acquisition system.
The unit is a very dense, portable, embedded solution for digital monitoring and control in any PC or embedded system with a USB port.
The unit contains an internal, removable screw termination board with onboard removable screw terminals to simplify wiring connections.
The USB-IIRO-16, like the PC/104 and PCI versions from Acces I/O, is excellent in applications where onboard relays are required and inputs must be isolated such as in test equipment, instrumentation and process control.

Board embeds waveform generation capabilities
The latest PC/104 board from Acces I/O Products combines eight independent 12bit DACs with broadly configurable arbitrary waveform generation capabilities.
The OEM version provides just the board without the enclosure and internal screw termination board and is ideal for a variety of embedded OEM applications.
What makes the OEM option unique is that its PCB size and mounting holes match the PC/104 form factor (without the bus connections).
This allows our rugged digital board to be added to any PCI-104 or PC/104 stack by connecting it to a simple USB port usually included onboard with embedded CPU form factors such as EBX, EPIC and PC/104 - especially important since many newer CPU chipsets do not support ISA and have plenty of USB ports.
Future stacks will be using the extremely fast PCI Express bus which is essentially overkill for simple digital monitoring and control.
The USB-IIRO-16 OEM board can also be added into many pre-existing standard PC/104 based systems and enclosures while the standard unit with its tiny enclosure and cable-less screw termination board provides portable connections to laptops for the mobile test market.
The industrial I/O market commonly uses electromechanical Form C relays due to their robustness and ability to withstand unexpected surge currents allowing for increased flexibility in switching capability.
These relays are also used where small reed relays are inadequate due to their susceptibility to contact damage.
The USB-IIRO-16 is fully compatible with both USB 1.1 and USB 2.0 ports.
The unit is plug-and-play which allows quick connect or disconnect whenever you need additional I/O on your USB port.
The module utilises a high-speed custom function driver optimised for a maximum data throughput that is 50-100 times faster than the USB human interface device (HID) driver used by many competing products.
This approach maximises the full functionality of the hardware along with capitalising the advantage of high-speed USB 2.0.
The USB-IIRO-16 is supported for use in most operating systems and includes a free Linux and Windows 98/2000/XP/2003 compatible software package.
This package contains sample programs and source code in Visual Basic, Delphi, C++ Builder and Visual C++ for Windows.
Also incorporated is a graphical setup program in Windows.
Third party support includes a Windows standard DLL interface usable from the most popular application programs.
Embedded OS support includes Windows XPe.
