Hardware Revisions
The nomenclature and positioning of hardware on Revision D is slightly differ-
ent than on Revisions A, B and C, but does not effect setup.

Rev A, B and C, without modules is shown in
Figure 2.2.1

Rev A, B and C, with modules, is shown in

Rev D, without modules, is shown in

DIP switches S1 and S2 are unchanged, as are the VCO, the connectors and the
LEDs.
The J1 is now the JP1, and the JP1 is now the JMP1, but they both serve the same
functions and are still both factory set. Do not remove the shunts.
2.3.2
Addressing the Board
The 4430-V/VN occupies 128 bytes of VME Standard Address Space. The de-
vice address is selected by setting DIP switches S1 and S2. Ones in the address
are noted by turning the corresponding switch section off. The switches are
equated to the address bits as shown in
Table 2.3.1
below.
Table 2.3.1: Address Switch Settings
The 4430-V/VN is a D08 VMEbus slave, which means it only uses the 8 low-
order VME Data lines at odd addresses.
