The EMX-2500 is the first gigabit Ethernet based PXI Express interface. This combines Ethernet's widespread usage and robust architecture with instrumentation-specific functionality, such as wired trigger bus and IEEE-1588-2008 synchronization, and extends it for use in PXI Express mainframes, making it an ideal solution for data acquisition applications
Simplified Instrument Discovery and Usage
When a mainframe with the EMX-2500 is connected to a local network, the EMX-2500 automatically assigns an IP address to the mainframe, allowing the chassis and the plugin cards to be accessed easily with the IP address. Any internet enabled device connected the local network can act as a host including desktops, laptops, tablets, and smart phones.
Precision Timing and Synchronization
The EMX-2500 contains a high-precision IEEE-1588 source for timestamping data and synchronizing modules within 100ns accuracy.
The precision timing sources can not only be used to synchronize modules within a single mainframe, they can also be used to synchronize data across multiple mainframes in a distributed data acquisition system.
When multiple mainframes are connected on a local network, the mainframe with the most accurate clock source will automatically become the master, and other mainframes will derive their clock from the master, simplifying data synchronization across multiple units.
High Data Transfer Rates – Up to 100 MB/s Sustained Throughput
The EMX-2500 uses gigabit Ethernet to achieve up to 100 MB/s sustained data transfer rate from the PXI express mainframe
Simplified Low Cost Cabling
Communication with the host processor is achieved using standard, low cost CAT5e Ethernet cable. In addition, standard Wi-Fi routers can be used along with the EMX-2500 to wirelessly control the mainframe.
Restful HTTP for Cloud Support and Advanced Web Applications
The EMX-2500 can deliver advanced data access and storage services throughout the organization using cloud data management services to stream data to remote servers. Data streamed to these servers can be accessed in a secure manner from any internet enabled device, from anywhere in the world.
In addition multiple mainframes can write time-stamped data to the same remote server, allowing widely distributed data acquisition systems.
Multiple Mainframes, Common Host
Unlike traditional embedded host controllers, the EMX-2500 allows multiple mainframes to be controlled by a common host. This allows for cost savings by reducing the number embedded host controllers and facilitates scalability by allowing software for all mainframes to be installed, run and configured on a single machine. Scaling up or down requires interfacing with a single machine.
Industry standard, drivers and programming interfaces provide the flexibility and freedom of choice to select the application programming environment best suited for the application and specific development requirements.
All major programming environments are supported including C/C++, C#, Visual Basic, Java, Python, Matlab, Labview and LabWindowsTM/CVI. VTI's innovative approach to driver development provides true OS independence without sacrificing the convenience that instrument drivers deliver. An IVI-like API can be imported into Linux and other operating systems. The intuitive APIs simplify programming. Therefore, low-level coding is not required to access the full capability of the instrument.
In addition, depending on the application requirements, a wide variety of turn-key software solutions are available for use with the EMX-2500 and SentinelEX hardware. For more information, refer to
The EMX-2500 can only be used with VTI's SentinelEX family of PXI Express modules providing a scaleable, distributed data acquisition system time-tagged with IEEE-1588.
