EX2500A Preface 7 http://www.vtiinstruments.com SECTION 1 OVERVIEW INTRODUCTION The EX2500A driver was written to be used with Agilent®VISA and, therefore, requires this software to be installed to function properly. Two software installation paths should be considered by users when installing the required EX2500A software: • Use with Agilent VISA software, where Agilent VISA is installed as the primary VISA. • Use with existing National Instruments©VISA (NI-VISA) software, which requires Agilent VISA to be installed as the secondary VISA and NI-VISA to be configured properly to support Agilent VISA. NOTE The screenshots provided in this section were captured on a Windows®XP® system using specific VISA (Virtual Instrument Software Architecture) installations. As such, it is possible that the images provided in this guide may not be identical to the images seen during a specific installation. VISA REQUIREMENTS In order to work properly in a test system, the EX2500A requires Agilent VISA to be installed on the host PC. Agilent VISA may be installed as either the primary VISA, or may be installed secondary to NI-VISA. The EX2500A is compatible with the following VISA software revisions: 1) Agilent VISA Revision 14.2 or later 2) NI-VISA Revision 2.6 or later for guaranteed operation (VTI Instruments Corp., however, recommends using revision 3.4 or later) Agilent VISA as Primary VISA Installation Path If Agilent VISA revision 14.2 or later is installed on the PC that will be connected to the EX2500A, go to page 14. If a different version of Agilent VISA is installed on the host PC, go to page 10 to install revision 14.2. It is recommended that previous versions of Agilent VISA be removed before installing revision 14.2. Agilent VISA as Secondary VISA Installation Path If NI-VISA revision 2.6 or later is installed on the host PC, go to page 23. If the version of NI-VISA installed on the host PC is lower than revision 2.6, please install an appropriate version of NI-VISA and then go to page 23.

VXI RST / LAN RST Button LXI LAN Configuration Initialize (LCI) Mechanism The VXI RST / LAN RST button, implemented according to the LXI LAN Configuration Initialize (LCI) Mechanism specification, on the EX2500A front panel provides a mechanism for recovery from an unknown or incorrect network configuration. If, for example, the EX2500A was statically configured for test or demonstration purposes and was not returned to “DHCP/AUTO IP” mode, the module may not be found by the original network setup. Following the procedure below will place the EX2500A’s IP configuration mode into “DHCP/AUTO IP” as well as ensuring that mDNS discovery is enabled: 1) Press and hold the reset button until the LXI PWR LED changes from red to green (approximately 5 s). 2) Release the reset button. NOTE Resetting the EX2500A will also reset the web page interface password to “ex2500”. VXI-11 Device Discovery (supported by the VISA IO-Libraries) is also supported by the EX2500A. This allows all EX2500A on a local network to be found without knowledge of their MAC address or IP address with the use of a broadcast message. GIGABIT ETHERNET FUNCTIONALITY The EX2500A automatically detects whether the twisted pair (RJ-45) or fiber optic (SFP) connection is active and switches without user intervention. For Cat 5e connections, the EX2500A provides auto-MDIX functionality that automatically handles crossover in point-to-point connections. The unit will also detect and correct pairs that are wired backwards. Therefore, crossover cables can be used, but are not required. NOTE If Cat 5e (RJ-45) and fiber (SFP) media are both connected at power up, the port that first achieves link (typically the SFP) will be used. Also, if a link is established on one media type, and the other media is connected, the established link is maintained. 40 EX2500A Quick Start Guide
