1.2.5 VOTER DIAGNOSTICS MODULE
The Voter Diagnostics Module (VDM), in the
Switch, is the data communication buffer between the
SMM and the Voting System (see Section 7). The type
of data exchanges between the Voting System and the
VDM pertains to: Memory Read of the voters;
Receiver Site Enable/Disable; and Alarm/Control
Information.
1.2.6 VOTER SHELF
Each Voter Shelf (VSH) contains 13 slots for
cRVM, RVM and CDM modules (see Section 8). The
maximum total of cRVMs/RVMs is 240, divide this by
13 slots and the total number of VSHs needed for
cRVMs/RVMs is 19. The maximum total of CDMs is
96, divide this by 13 slots and the total number of
VSHs needed for CDMs is 8. The maximum possible
total number of VSHs is 27.
1.2.7 VOTER POWER SUPPLY
Each Voter Power Supply (VPS) has the capacity
to handle two VSHs (see Section 9). The maximum
total of VSHs is 27, divide this by 2 and the total num-
ber of VPSs needed is 14. There are two VPSs per
power shelf, therefore, 7 power shelves are the maxi-
mum number per system.
