1. Figure C 4 CLK10 Signal Routing It is important to note that when the EXT CLK connector is not being used as an input to drive the VXI CLK10 signal that is S2 is set to OUT it serves as an output onto which the VXI 8340 series drives the CLK10 signal UN Caution If S2 is set to OUT do not attach any device that will drive a signal to the EXT CLK connector Doing so may damage the device or your VXI 8340 series module National Instruments Corporation C 5 VXI 8340 Series User Manual Power Sequencing Requirements The VXI 8340 series uses MXI 3 technology to extend the PCI bus of a host computer to a VXI chassis transparently so your host computer can function as an embedded CPU module Because of this transparent PCI extension it is important to maintain a strict power on sequence when turning on VXI chassis in a VXI 8340 system For the system software to discover and configure a VXI 8340 series controller power on all VXI 8340 chassis in the system before enabling power on the host computer If any chassis is not present when the host computer initiates its boot process the host computer may not configure that VXI controller If a VXI system is absent when the system boots the host must be rebooted to discover the missing VXI system 3 Note You must power on the VXI 8340 series at least 8 seconds before your PC When daisy chaining VXI 8340 series controllers power on VXI chassis in reverse order starting with the

There are several reasons why you might get the Configuration EEPROM is Invalid message If you turned off the VXI chassis while the configuration update process was still in progress the module functions normally except when running MAX To correct these problems reboot the VXI chassis with the Load Factory switch set as described in Appendix C Advanced Hardware Configuration Settings and update the configuration or load the configuration from file What do the LEDs on the front of the VXI 8340 series mean e The FAIL LED indicates that the VXI 8340 is driving SYSFAIL onto the backplane e The ONLINE LED indicates when the VXI 8340 series is online When it is offline you can safely power cycle the VXI chassis e The Link 1 LED indicates that a communication path has been established with the device attached to MXI IN e The Link 2 LED indicates that a communication path has been established with the device attached to MXI OUT e The SYSF LED indicates that the VMEbus SYSFAIL line is asserted National Instruments Corporation E 3 VXI 8340 Series User Manual Appendix E Common Questions VXI 8340 Series User Manual e The ACC LED indicates that the VXI 8340 is decoding a VXI cycle The TX RX LEDs indicate that the VXI 8340 is receiving data through the MXI port when green and transmitting data through the MXI port when yellow What kind of signal is CLK10 and what kind of signal do I need for an external CLK10
4. The functions MapVXIAddress and viMapAddress check whether a window that can be shared already maps to the desired address space and location If so they return a pointer to that window If the desired space is not already mapped they set up a new MITE window to the VXI address and return a pointer to the new window The MapVXIAddressSize function is the standard mechanism for specifying how large a window the driver should map on a call to MapVXIAddress The default size of a mapped window when using NI VXI is 64 KB In VISA you specify the window size directly in viMapAddress The success of this allocation depends on the availability of three factors e Address space in the User Window e Number of MITE windows e Memory for allocating data structures for the map 3 6 ni com Chapter 3 Developing Your Application Address Space The VXI 8340 series can decode any 32 bit address on the PCI bus as a VXI cycle giving 4 GB of addressability which can be used for windows on the VXI 8340 series The operating system or computer architecture may limit which addresses can be assigned to the VXI 8340 series To change the address space edit the User window size field in the PCI tab of the VXI 8340 series Hardware Configuration settings in MAX This setting limits the total amount of memory you can map with MapVXIAddress or viMapAddress If the User Window is disabled the MapVXIAddress function returns NO_HARDWARE SU
