$020000 to $02029F. If this base address is unsuitable, before installation, remove
the cover from the L5211 (which has the LINK product label attached) by removing
the six flat head screws. Refer to Figure 7 which shows the location of JMP2. By
changing the jumpers at JMP2, any starting address from $00000 to $FF800 on 32K
boundaries may be configured. Configurations are accomplished by installing or
removing (in or out) Berg post jumpers.
&DXWLRQ
Observe static discharge precautions when handling the L5211,
especially when the cover is removed.
&DXWLRQ
Do not touch the flex circuits when the cover is removed from the
L5211. They are fragile and can easily be damaged.
JMP2 positions 1-2 and 3-4 determine if the 32K boundary is upper or lower within
64K; that is, nn000 (JMP2 3-4 in) or nn800 (JMP2 1-2 in), hence are mutually
exclusive and must not be installed at the same time.
JMP2 positions 3 through 10 represent a zero if installed or a one if removed and
correspond directly to the high order address bits. If JMP2 19-20 is installed, address
bit 23 is a zero. If JMP2 5-6 is removed, address bit 16 is a one. Refer to the
following table for examples.
