PCIe-DIO-24DCS Digital I/O with Counters and COS IRQ FEATURES  24 high-current DIO lines  Three optional 82C54 Counter/Timers  IRQ generation from Port C bit 3, Counter A2 (“C” models) or Change of State (COS) Detection (“S” models)  DIO lines buffered  Four and eight bit ports independently selectable for inputs or outputs  Jumper selectable 10k ohm Pull-up/Pull-down resistors on DIO lines  Jumper selectable VCCIO (5V, 3.3V, 2.5V, 1.8V)  VCCIO voltage available to the user via 0.5A resettable fuse FACTORY OPTIONS  Extended temperature operation (-40° to +85°C) FUNCTIONAL DESCRIPTION This product is a x1 lane PCIe DIO board available in four models ranging from basic DIO to advanced COS detection and Counter/Timer capabilities. The card emulates an 8255 compatible chip, providing 24 DIO lines. The DIO lines are grouped into three 8-bit ports: A, B, and C. Each 8-bit port is configured via software to function as either inputs or outputs. Port C can be further broken into two 4-bit nybbles via software and configured as either inputs or outputs. Each DIO line is buffered and capable of up to 32mA source/sink. The VCCIO logic level is globally configured via jumper selection as 5V, 3.3V, 2.5V or 1.8V. Also, ports A, B, C low nybble, and C high nybble are individually jumper configurable as pull-up or pull-down through 10kΩ resistor networks. The card is 6.6 inches in length and 4.2 inches seated height. I/O wiring connections for this board are via a male 37-pin D-sub connector. A ribbon cable can be used to connect this card to termination panels. ACCESSORIES ADAP37 DB37F screw terminal board plugs directly onto the card’s I/O connector CAB37-XX Ribbon Cable Assy, XX=length in inches STA-37 Screw terminal board mounted on standoffs with bread-board area T-BOX Metal enclosure with powder coated finish, use to mount STA-37 to panel STB-37 Screw terminal board, ships with standoffs but can also mount on SNAP-TRACK or DINSNAP DIN-SNAP-6 SNAP-TRACK for DINrail mounting one STB37 SOFTWARE The card is supported for use in most operating systems and includes a free DOS, Linux, and Windows 2000/XP/2003/Vista/7 compatible software package. This package contains sample programs and source code in Visual Basic, 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. Embedded OS support includes Windows XPe. 10623 Roselle Street, San Diego, CA 92121 • (858) 550-9559 • Fax (858) 550-7322 • contactus@acces
