The NV9 banknote Validators have a unique address – 00110XXX binary (30H). The VMC
polls the bus to detect presence of the NV9 Validators or get information on the current
status of the Validators.
The Validators will respond when asked for activity with an acknowledgment, a negative
acknowledgment or a specific reply, depending on its current status. Bus crashes are
avoided as the Validators respond to being polled only by the VMC.
The international country code must be set for the country in which the Validators will be
operating. This is either the international telephone code for that country, or the country
code taken from ISO4217. The code is represented as two bytes. The initial digit signifies
the source of the code. 0 signifies the telephone code is used, 1 signifies ISO4217 has
been used.
For the USA the country code is 00 01, or 18 40
For Great Britain the code is 00 44, or 18 26.
The scaling factor must also be specified for each Validator. All accepted note values must
be evenly divisible by this number.
•
This number would be set to 100 (Hex 64) for the Euro or Great Britain.
•
The number would be set to 1000 (Hex 03E8) for Columbia.
•
The number of decimal places must also be programmed for each Validator
•
The number would be set to 2 for Euro or USA
•
The number would be set to 3 for Columbia
Adopting the numbers above:
•
£5 would be displayed as 5.00
•
£10 would be displayed as 10.00
•
$1 would be displayed as 1.00
•
1K Columbia would be displayed as 1.000
6.8 ccTALK PROTOCOL – CCT
The NV9 supports the ccTalk serial protocol for easy interfacing with host machines that
support this protocol.
To use ccTalk mode DIPswitches 3 and 4 must be in the Up position to select ‘Special’
mode on the validator and the CCT option of the interface firmware must be loaded into
the NV9. (DIPswitch 2 is non functional in this mode).
Pin out connections on NV9 for ccTalk are shown below (see figure 7) looking at the
connection pins on the NV9 interface connector as defined in the ccTalk specification. All
communications with the note validator must be encrypted using the encryption key, the
default encryption key will be printed on the label of the NV9.
NOTE: For detailed information and full protocol specification please refer to
