3.5.1 Opto-Isolated Inputs
The NV200 natively supports Opto-isolated communication, the connection requires
a reciprocal circuit to be established on the host side. The pin outs for the opto-
isolated inputs can be found in section 5.2.2.
3.6 Reliability Data
Below is an explanation outlining the Mean Cycles Between Failure (MCBF) & Mean
Cycles Between Interruption (MCBI) for the NV200 family of products. Where a cycle
is defined as a note/ticket either stacked, stored or paid-out. An example is if £20 is
accepted and a £10 paid out that would be classed as 2 cycles.
The difference between MCBF and MCBI is that a failure is classed as an event which
will require a service call – e.g. unit is seeing poor acceptance. Whereas an
interruption is an event which store/site staff could rectify without a trained engineer
present – e.g. clearing a note path jam.
As explained in section 2.4 the NV200 is a modular solution and these modules
increase the complexity of the system. As such each time, one of these additional
modules are attached the current MCBF and MCBI is halved.
MCBF data is available upon request from ITL.
3.7 Media Requirements
The NV200 is capable of handling multiple denominations simultaneously, the media
that can be accepted includes but is not limited to:
- Polymer notes
- Windowed notes
- Barcoded tickets
The minimum and maximum dimension for media IN is as follows:
