224 TTL Channels, Digital I/O with 4 Counters PXI Card

  • Highest PXI digital I/O channel density in the industry
  • Seven 32-bit ports for a total of 224 input or output channels
  • TTL Levels
  • Four 8-bit, 50 MHz counters


The GX5732 is a 6U PXI static digital I/O card with 224 TTL I/O channels. Designed for ATE, data acquisition, or process control systems where a large number of discrete I/O channels are required, the GX5732 offers the highest digital channel density in the industry for a single PXI plug-in board.


The GX5732 provides 224 TTL channels that are programmable for either inputs or outputs in groups of eight. The GX5732 has no on-board memory and uses the computer’s memory and CPU power for data transfer.

The GX5732 also has four 8-bit, bi-directional, 50 MHz counters. Eight I/O pins on the counter port can be used as inputs or outputs to any of the counters. An additional 4 outputs can be used as counter outputs or as a Terminal Counts (TC) for all counters. Six programmable inputs are provided for counter control: clock, gate, or load. The counters may be daisy chained to create two 16-bit counters, or one 32-bit counter. The clock source can be the PCI clock, PXI clock, an external clock, or another counter.

Programming and Software

The board is supplied with the GXPIO library, a software package that includes a virtual instrument panel, and a Windows 32/64-bit DLL driver library and documentation. The virtual panel can be used to interactively program and control the instrument from a window that displays the instrument’s current settings and status. In addition, interface files are provided to support access to programming tools and languages such as ATEasy, LabView, LabView/Real-Time, C/C++, Microsoft Visual Basic®, Delphi, and Pascal. An On-Line help file and PDF User's Guide provides documentation that includes instructions for installing, using and programming the board.
A separate software package - GtLinux - provides support for Linux 32/64 operating systems.
