The GX5733 is a 3U modular digital I/O card that offers up to 128 I/O channels. Designed for ATE, data acquisition, or process control systems where a large number of discrete I/O channels are required, the GX5733 offers the highest channel density and flexibility in the industry for a single-slot, 3U PXI plug-in board. 96 channels support TTL levels and an additional 32 I/O channels can be customized by installing one of Marvin Test Solutions’ GX57xx series I/O modules. Alternatively, the remaining port can be configured to support 32 TTL channels.
Features
The GX5733’s 128 digital inputs or outputs are arranged as four, 32-bit ports. Three of the ports provide 96 TTL levels and can be programmed for input or output in groups of 8. The remaining port can be used with a GX57xx I/O module and offers customized levels, handshaking, and on-board memory. The GX57xx expands the I/O capability of the GX5733 to 128 input or output channels.
I/O Modules
The GX5733 can accommodate one GX57xx module and provides custom I/O levels and functions. I/O modules provide between 16 and 32 channels with some versions offering on-board memory.
GX5701 – Digital Input Latch (DIL)
The GX5701 provides 32 input channels with programmable threshold (-30 V to +30 V), handshaking for synchronization, and 16 KB of vector memory.
GX5702 – Digital Output Latch (DOL)
The GX5702 provides 32 TTL output channels, handshaking for synchronization, and 16 KB of vector memory.
GX5704 – Digital Power Output Latch (DPO)
The GX5704 provides 32 optically isolated Open-Collector Outputs capable of driving signals up to 50 V with 500 mA current sink capability, handshaking for synchronization, and 16 KB of vector memory.
GX5709 – RS-422 Differential Digital I/O
The GX5709 provides 32 RS-422 differential I/O channels. Direction is programmable in groups of eight.
GX5711 – LVDS to TTL Converter
The GX5711 bi-directional I/O module converts 16 differential LVDS inputs to TTL outputs or 16 TTL inputs to 16 differential LVDS outputs.
GX5712 – RS-422 to TTL Converter
The GX5712 bi-directional I/O module converts 16 differential RS-422 inputs to TTL outputs or 16 TTL inputs to 16 differential RS-422 outputs.
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.
