M.2-IDIO-8, M.2-IDO-8, and M.2-IDIO-4

The M.2-IDIO-8 consists of a 2260/2280 sized M.2 Card interface board that connects to a Mobile-ITX-sized, DB-37M Isolation Module via an included 9” cable. That module is designed to be easily panel-mounted in any application environment. It uses the high speed PCI Express bus to transfer digital data to and from the card. The digital I/O is compatible with 8255 PPI chips making it easy to program. This allows for simple and trouble-free migration from other ACCES PCI and PCI Express digital I/O cards, but also provides for advanced features enabled by the onboard FPGA logic.

The M.2-IDIO cards are well suited to complex environments, mitigating otherwise challenging ground-loops, high-common-mode, and transient voltage spikes common in electrically-noisy industrial or factory locations. The broad voltage compatibility and high current outputs allows use in a wide range of applications.

The non-polarized inputs support both AC and DC, and configuration jumpers allow 4.7ms input filters to be enabled per-channel, as desired – required for AC use. The isolated inputs support voltages from 3 to 31 VDC/VAC RMS [40Hz to 10000Hz], as well as standard 12/24 AC control transformer signals.

The outputs are fully protected High-Side Power MOSFETs capable of switching from 5 to 34VDC at up to 2A continuous-current load with 10A max current allowed (VBB0 = 5A, VBB1 = 5A).

Change of State (COS) detection and interrupt capabilities are designed to relieve software from polling routines that can consume valuable processing time. Each port can be programmed for detecting state changes on their lines, in which any changes of the enabled port's bits (low-to-high or high-to-low) will generate an IRQ. An ISR (interrupt service routine) then determines which bit changed state and clears the interrupt.

Digital∫Features

Digital∫Features (read as "Digital Integration Features") are a new family of features available for applicable models of ACCES' PCI Express (PCIe) and M.2 Card (mPCIe) Digital I/O product lines.

All the cards share features such as memory mapped registers for low-latency operation. Output channels support pulse/train / PWM / frequency / and quadrature generation. Inputs channels support flexible measurement of pulse duration, frequency, and event counting, with optional debouncing, IRQ generation, and more.

Applications

The M.2-II-16 is excellent for use in a variety of applications where high-voltage protection is required such as:

• Factory Automation
• Industrial ON/OFF control
• Security Systems, Energy Management
• Process Monitoring
• Manufacturing/Production Test
• Machine Control
• Monitoring and Control
• Industrial Automation
• Embedded OEM

Accessories and Connections

Available accessories include a variety of screw terminal boards for quick and easy connectivity as well as 2mm and 2.5mm mounting hardware. Alternately, custom hardware cables and/or interfaces can be produced to fit your specific application requirement.

SOFTWARE

The card is supported for use in most operating systems and includes a free DOS, Linux , and Windows 2000/XP/2003/Vista/7/8/10 compatible software package. This package contains sample programs and source code in C#, Delphi, and Visual C for Windows. Also provided is a graphical setup program in Windows. Linux support includes installation files and basic samples for programming from user level via an open source kernel driver. Third party support includes a Windows standard DLL interface usable from the most popular application programs, and includes LabVIEW VIs. Embedded OS support includes Windows XPe, WES7, WES8, vxWorks, etc. Full register-level documentation of all features ensures easy compatibility in any application environment.

AIOSerial/VxWorks

ACCES has successfully partnered with Wind River to bring our entire line of PCI and PCI Express Serial Communication cards to VxWorks 7! All ACCES plug-and-play serial cards are now supported with our VxWorks driver, including RS232, RS422, RS485 (2- and 4-wire) and baud rates up to 10Mbps.

Designed as an update to the existing vxbPciNs16550Sio.c driver, we've added support for ×8 baud rates, proper handling of the unique register location of the 4th port in the Pericom PI7C9X7954 UART, and configuring the serial protocol from your application software.

With this driver suite all ACCES PCI, PCI Express, PCI Express Mini Card, M.2, PCI-104, PCIe/104, and all related "PCI Style" plug-and-play serial cards will detect and install as standard VxWorks SIO ports.
