D 2 National Instruments Corporation Appendix D PC Card Questions and Answers 5 Irun a memory utility and it appears there is no memory available for Card Services What should I do You should remove your memory manager by commenting it out of the CONFIG SYS file Next you can rerun the memory utility Memory managers often consume an enormous amount of memory and you will need to determine what memory is really usable by Card Services When you have determined what memory is available for Card Services reinstall your memory manager and make the necessary changes to provide Card Services with the memory needed We suggest that you use the minimum amount of memory for Card Services namely 4 to 12 KB which frees more memory for the memory manager Resource Conflicts 1 How do I resolve conflicts between my memory manager and Card Services Card Services can usually use memory space that is not being used for real RAM on the system Even when this is the case you should still exclude the memory addresses used by Card Services from use by any memory manager that may be installed National Instruments Corporation D 3 DAQCard 500 User Manual Appendix E Power Management Modes This appendix describes the power management modes of the DAQCard 500 e Normal Mode This is the normal operating mode of the DAQCard 500 in which all the circuits are fully functional This mode draws about 60 mA from the 5 V supply about 300 mW

ER_EXE will switch all National Instruments PC Cards between normal mode and power down mode Power up and power down icons are also installed for Windows users to access either of these two power management modes Resources 1 How do I determine if I have a memory conflict If no PC Cards are working at all it is probably because a memory window is not usable Card Services uses a4 KB memory window for its own internal use If the memory cannot be used then Card Services cannot read the Card Information Structure CIS from the card s EPROM which means it cannot identify cards There are two different methods you can use when Card Services has a problem reading the CIS First you can determine which memory window Card Services is using and then exclude that window from use by Card Services and or the memory manager Second you can attempt to determine all of the memory that Card Services can possibly use and then exclude all but that memory from use by Card Services 2 How do I determine all of the memory that Card Services can use One way to find out which memory addresses Card Services can use is to run a utility such as MSD EXE that scans the system and tells you how the system memory is being used For example if you run such a memory utility and it tells you that physical addresses C0000 to C9FFF are being used for ROM access then you know that C8000 D3FFF is an invalid range for Card Services and should be changed to CAQ00
