3.4.3 Power Supply Guidance
The NV9 Range of products require a stable 12V DC power supply. Please check the
power requirements of your host machine and other peripherals to dimension a
suitable power environment for your machine setup.
TDK Lambda manufactures suitable power supplies. Please see table below for
further details.

3.6 Reliability Data
The below data refers to the Mean Cycles Between Failure (MCBF) and the Mean
Cycles Between Intervention (MCBI). The difference between the two is that a
failure would usually require the unit being replaced. Whereas an intervention would
be an issue that is easily clearable such as a reset or clearing a note path jam.
A cycle is classed as a note or ticket being either accepted or dispensed. For
example; if a unit accepts a note and then dispenses a note as change, it is classed
as two cycles.
NV9USB+
MCBF: 200,000 Cycles
MCBI: 100,000 Cycles
It is important to note that when adding a recycler or printer, you are doubling the
number of modules. Thus, the MCBF/MCBI will naturally be halved.

The NV9 range supports multiple currencies and denominations as per the
specifications detailed in the table above. Furthermore polymer and windowed notes
are in use in a number of countries and so are already fully supported on the NV9
range of validators.
3.7.2 Tickets
The NV9USB+ validator is only able to read and accept barcode tickets, if the printer
module is attached (NV12+). The below information specifies the ticket dimensions
as well as the barcode requirements.
3.7.2.1 Ticket Dimensions
Tickets should have a width (A) of 65mm to 82mm, the smaller the ticket the larger
barcode width should be used.

<< Back to Contents
Copyright © Innovative Technology Ltd 2018 Doc: NV9 Range User Manual
Version: 1.0
Page 15 of 63
The length (B) of the ticket is variable, tickets between 90mm and 166mm are
acceptable.
3.7.2.2 Barcode Requirements
The interface the validator is operating in will change the possible value of the
barcode number.
SSP: Barcode length can be between 6 to 24 characters.
ccTalk: Barcode length is fixed to 18 characters, however this is configurable.
Dimension
The barcode itself should be no thinner (E) than 10mm. The narrow bar width
between 0.5mm and 0.6mm, with the wide narrow ratio (W:N) being 2:1.
A blank space (C) is required on either side of the barcode as pictures or text may
be seen as part of the barcode value.

4MECHANICAL INSTALLATION
4.1 Compatibility
4.1.1 Hardware Compatibility
4.1.1.1 Machine Mounting
Assuming the suitable bezel (and cashbox) type has been ordered the NV9USB
range can be used as fitting replacement for the following products:
•NV7
•NV7M
•NV9
Please note: Considerations will need to be made when adding either the recycler
or printer module, as this will increase the space requirements inside the host
machine.
The NV11+ and NV12+ have the same space envelope so swapping the recycler for
the printer will not require any mechanical adjustments.
Innovative Technology Ltd. has a policy of continuous product improvement. Due to
design changes, older model or product bezels (and cashboxes) may not be
compatible with the current NV9USB+. However, new product deliveries always
include a bezel (and cashbox) that must be used.
4.1.1.2 Machine Interfacing
By design the NV9USB+ and NV11+ are pin to pin compatible with the fitting
replacement products listed above. No changes to existing machine harnessing are
required.
The NV12+ has an additional connector, in order to power and communicate with
the printer head.

4.1.1.3 Power Supply
It is vital that the product is connected to a power supply being able to provide the
required power environment. A weak power supply can lead to unexpected
behaviour such as note rejects or missing credits. If you are replacing an older
model or product we recommend checking the power supply specifications of the
machine. The newer models might have higher power consumption. Refer to 3.4 for
full power requirement details of the full NV9 range.
4.1.2 Software Compatibility
4.1.2.1 Interface Protocols
When using the NV9 range of products as a fitting replacement for an older model or
product some events such like credits may be given earlier. This is due to improved
firmware routines and faster motors being used. This may cause missing events
such like credits in those host machines where timeouts are defined for the older
model or product. Please contact the machine manufacturer for full compatibility.
4.1.2.2 Re-programming
For re-programming the units always use the latest version of Validator Manager,
available for download from our website. Newer products may not be fully supported
on older versions of Validator Manager. For further details on Re-programming, refer
to 5.4.
