24. ting the Base Address on page 16 Insert the B201S into your VMEbus system making sure that the VMEbus con nectors are properly aligned Note The B202S is slightly higher than standard 3U Eurocard format so that it can accommodate two M Modules Its dimensions are 110mm by 155mm Because of this deviation you need special guide rails to install the B202S in your 3U VMEbus system which are included in the stan dard B202S delivery The rails are also available as a standard product directly from Schroff guide rail for 4 4 cards order no 60817 038 Power up the system After power up load a suitable debugger First attempt to perform a read word access to the base address plus 0x100 i e OXEO0100 if the base address was not altered With 32 bit masters it may be necessary to load a register on the master board to set the access mode In any case you should be aware of the contents of the high order byte of the 32 bit address For instance access may require using address OXFFE0O0100 or OxFCEO0100 If a bus error occurs while you are attempting to read check if the base address is set correctly and whether it is possible for the master to access the VMEbus at all at the selected address and using the correct mode Then try again Now attempt to perform a word access to the base address plus 0x102 Again no bus error should occur Write accesses to this memory location should be successful for the right half of the word For
