To use the MDB mode an IF5 interfa
D IPswitches 3 & 4 must be in the up position to select 'Special' mode on the validator and
the MDB option of the interface firmware loaded into the NV9. (DIPswitch 2 enables a
fast reset on power up).
Th e Fast Reset option should be set if the NV9 continuously resets the stacker after the
machine is powered on. The Fast Reset option can be enabled via the Validator Manager
Software, or by setting Dipswitch 2 to the ON position.
Note:
Please refer to the Multi-Drop Bus specification for the suggested current drive
circuits available
The NV9 supports the MDB protocol version 1, level 1
