NVSIM
The Smiley Note Validator
Simulator
NVSIM is a Smiley Note Validator
Simulator, designed to help Design Engineers, Test Houses and Service Personnel, exercise
the Note Validator Input on machines supporting this popular Note Validator. The board has
several modes of operation, and will truly mimic the output of a Smiley Validator without
the need to insert Notes etc. When running in standard mode, four push buttons on the
NVSIM, mimic the 4 different Note Channels. By pushing these buttons, NVSIM toggles the
relevant output for an accurate 100ms (the standard pulse length for this type of
operation). An LED on NVSIM indicates when any output is being toggled. NVSIM also tests
the "Alarm" and "Busy" inputs of machines. There are two connectors on
NVSIM, one for NV2, NV4 type machines and the other is for NV7, NV8 type machines. NVSIM
has an "AutoCycle" button which when pressed, continuously toggles each of the 4
Note Channels in turn, thus suitable for long soak tests etc.
