/> These PC/104 utility boards feature three conditioned differential inputs including indexing per channel. The eight pins per channel are accessed via two 34-pin IDC type headers, which include a resettable 0.5A fused 5V output and ground pair to power most common encoders. The board requires only +5V at a mere 260mA and includes a 16-bit pass-through PC/104 connector for easy system development and integration. Available accessories include a variety of ribbon cables, DIN-rail mountable screw terminal boards, as well as connector/screw terminal combinations which plug directly onto the header pins of the board.

Key features of the 104-QUAD-8 include:

* 4, 6 or 8 channels of quadrature encoder and channel index inputs
* Three differential channels per encoder, including dual axis and index
* Resettable fused +5VDC available per channel
* Input ranges: ±25V and ±7V common mode
* 4.3MHz maximum clock rate with digital filtering
* 24-bit dual axis quadrature counter LS7266R1 with selectable X1, X2 or X4 decoding modes
* Individual software reset for each channel
* Programmable for counting, speed, and direction; limit setting with interrupts
* Optional -40°C to +85°C operating temperature
* Optional latching I/O connectors

These boards are supported for use in most operating systems and include a free DOS, Linux and Windows 98/NT/2000/XP/2003 compatible software package. This package contains sample programs and source code in C for DOS, and Visual Basic, Delphi, C++ Builder, and Visual C++ for Windows. Also incorporated 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 example LabVIEW VIs. Embedded OS support includes Windows XPe and CE.
