VXI Technology's EX2500 lets you control a VXI chassis and instruments over an Ethernet link. With this slot-0 controller, you can remotely control a VXI chassis with Cat5 cable over distances up to 200 m. With a fiber-optic link, you can control a VXI chassis and its instrument modules from up to 10 km away. Data transfer rates can reach 40 Mbps.
The EX2500 works with Windows 98 and higher. It's VXIplug&play compliant, so you can use the Agilent Technologies' or National Instruments' versions of the VISA I/O library to communicate with instruments. Thus, you can still use your VXIplug&play instrument drivers and application code. The controller also supports the Agilent I/O Library suite, version 14.1. On power up, the EX2500 runs the VXI resource manager, which tells the host computer which instrument cards are in the chassis.
The EX2500 lets you use the eight VXI backplane trigger lines with Ethernet based instruments that comply with the LXI standard. The controller's front-panel LXI trigger-bus connectors let you connect the EX2500 to the LXI trigger bus. You can use LXI triggers initiated by LXI instruments to trigger VXI instruments in your chassis. Conversely, you can trigger an LXI instrument based on a measurement taken by a VXI instrument.
