2.1.2 Additionalusefultechnicaldocumentation
Apartfromtheseoperatinginstructions,thereisfurtherdocumentationforthev2colibri. You
candownloadallthedocumentationPDFlesbyvisitingwww.craneps.com.
2.2 About the v2colibri
The v2colibri coin validator with a serial ccTalk interface in the standard 3.5“ format is based
on the tried and tested features of the G-13.mft and also uses the patented multi-frequency
measuring technology (MFT) for reliable coin validation. Communication with the machine control
isviaaccTalkspeciedfour‑pinmaleconnector.Duetoitscompactandmodulardesign,the
v2colibriisusedaboveallinentertainment,vendingandservicemachines.
Forcoinacceptance,thecoinvalidatorhasavailable32coinchannelsthatcanbemanaged
either in a single memory block or divided into two memory blocks – 2 x 16 coin channels – with
differentcoincongurations;inbothcases,theblockscanbeswitchedonanindividualbasis.
Dependingontheapplication,youcantthecoinvalidatorwithanoptionalfrontplateandit
can control a 3-fold sorter.
Tobeabletoreactasquicklyaspossibletonewfalsecoinsandtomakeyourindividualsettings,
thecoinvalidatorcanbeconguredonsiteinthemachineusingaservicetoolorintheworkshop
via a PC programming station.
Youcanalsocongurecoinsortokensthatareignoredex‑workswithoutneedingconguration
software,youjustinsertthecoinsinteachmodeonthecoinvalidator.
2.2.1 v2colibri properties
• ReliableacceptanceofgenuinecoinsandrejectionoffalsecoinsduetoMFTmultiple

coin sensor in the coin validation and coin outlet area
• String recognition
• Acceptance speed of two coins per second
• Switchable Casino mode for speed of coin acceptance – up to six per second are possible
• 32coinchannelsmanagedinoneortwomemoryblocksthatarecongured
independently of one another and are switched individually (2 x 16 coin channels)
• Serial interface

• Options
–Top or front entry version
–MINI or MIDI front plate
–SSD-3000 3-fold standard sorter or HSD-3000 3-fold high-speed sorter
–LicenceforupdatingthecompleteccTalkcoinanddevicecongurationonmachines
with PC-based control (remote data block upload)
–ACMI write protection
–Additional tamper protection by protocol encryption: BNV (Bill Note Validator
encryption),DES(DataEncryptionStandard)
2.2.2 Modelsandoperatingmodes
There are different versions of the v2colibri available. They mainly differ
• in the coin entry and return area
• in the communication protocol and
• in the acceptance speed.
2.2.2.1 Coin entry and return area
• Top entry and return at the bottom right (36Bxx. ..)
You insert the coin from the top into the device and it is returned via the return at the bottom
right should it not be accepted (cf. Chap. 4.2 Coin path, p. 15).
• Top entry and return at the bottom left (31Bxx. ..)
You insert the coin from the top into the device and it is returned via the return at the bottom
left should it not be accepted (cf. Chap. 4.2 Coin path, p. 15).
• Front entry and front return (39Bxx. ..)
You insert the coin from the side into the device and it is also returned at the side should it not
be accepted (cf. Chap. 4.2 Coin path, p. 15).Onthiscoinvalidator,youcanpushontheoptional
NRI MINI or MIDI front plates on the left-hand side of the device (cf. Chap. 10.3 Accessories, p. 44).
2.2.2.2 Communicationprotocol
The coin validator communicates with the machine controller via the serial ccTalk protocol.
The coin validator works as slave and the machine as master. The ccTalk protocol is open for
everybodyandcanbeusedwithoutrestrictions.Anotheradvantageisremoteuploading,i.e.
itispossibletoloadcompletecoinandmachinecongurationsintothecoinvalidatorviathe
ccTalk interface from a host computer too. Two versions are possible:
• Standard
ProtocolaccordingtoccTalkspecication.
• ACMI
The factory programming of the coin validator in this model meets all requirements of
the Italian gaming machine act "legge 289 – comma 6" passed in July 2003. The ACMI
version of the v2colibri is write-protected so that it is not possible to change the factory
programmingusingcongurationtools.
In order to meet the requirements of the Italian gaming machine act subsequent
conguration of the ccTalk ACMI model is impossible. If you want to change the
factory settings please contact our sales representative.

2.2.2.3 High-speedacceptance(Casinomode)
It is possible to run the v2colibri ccTalk in what is known as Casino mode if it is used in gaming
machines and needs to accept coins particularly quickly (up to 6 coins per second).
In Casino mode, the v2 colibri runs in favour of fast coin acceptance without
accepted coin sensing (cf. Chap. 5.3 Accepted coin sensor, p. 20).
2.2.2.4 Protocol encryption
Usingprotocolencryption,itispossibletoadditionallyprotectthecoinvalidatorfrommanipulation:
• BNV (Bill Note Validator encryption)
• DES (Data Encryption Standard)

5 Function
This chapter describes how the coin validator works:
• Coin acceptance and coin channels
• Single or double block data-management
• Accepted coin sensor
• String recognition
• Control for external sorting device
• Coin inhibition/activation of narrow coin channels
• Teach mode
5.1 Coin acceptance and coin channels
For coin acceptance the coin validator has 32 "memory blocks" to which up to 32 different coin
types or tokens can be assigned. These "memory slots" are called coin channels. The acceptance
band of one coin type/token is assigned to each coin channel and the respective coin type/
token is accepted in this channel.
After a reset, coin acceptance is inhibited and must be enabled by the machine.
By default, the v2 colibri refuses to accept any further coins if the machine had
not addressed it within the last 500ms or if the machine has not yet polled the
last accepted coin.
Toenablereliablerejectionoffalsecoins,channelswithanarroworevenverynarrowacceptance
band are frequently set up for a coin type in addition to the normal coin channel. The limit values
of these coin channels are closer together so that counterfeit money with similar measured values
canberejectedifthenormalchannelisdisabled
(cf. Chap. 7.2 Inhibiting coins/activating narrow coin channel ...,
p. 29).However,narrowandsuper‑narrowcoinchannelsalsohavealoweracceptancerate.
Inaddition,itispossibletoassigncoinswithdifferentmeasuredvaluesbutidenticalcoinvalues
to different coin channels. In this way the coin validator can accept e.g. old and new coins of
the same denomination.
Inadditiontotheacceptancebandofacointype,furthercoininformationwhichdenesfurther
processing of the coin after its acceptance is assigned to a coin channel: e.g. the coin value or
sorting information for an external sorting device.
Since in most cases not all coin channels are assigned by customized factory programming,
further coin types and the desired information can be assigned to these free channels at any
timeusingtheNRIcongurationandservicetools.Existingcongurationscanbechanged.
The last eight coin channels 25 to 32 (or 9-16 with double block data-management (cf. Chap. 5.2
Single or double block data-management, p. 20))areintendedforteachmode.Intheseteachchannels,
you can also teach new types of tokens/coins directly via the switch blocks on the coin validator
withoutneedingcongurationandservicetools;i.e.anewcoinortokenisassignedtoachannel
(cf. Chap. 5.7 Teach mode, p. 23).

5.1.1 QuickcoinacceptanceinCasinomode
If you are using the v2colibriingamingmachines,thedevicecanbeswitchedtoCasinomode
so that inserted coins can be accepted faster (up to six coins per second instead of two per
second) (cf. Chap. 7.4 Activating Casino mode, p. 34).
5.2 Singleordoubleblockdata-management
Atthe factory,the deviceis programmedon acustomer‑specicbasis whetherthe 32 coin
channelsofthecoinvalidatoraremanagedinonememoryblockor,dividedupinto16channels
each,intwomemoryblocks(doubleblockdata‑management).
Ifdoubleblockdata‑managementiscongured,thev2colibri can manage two (memory) blocks 0
and 1 that are programmed independently of one another (cf. Chap. 4.3 Nameplate, p. 16). 16 coin
channelswithdifferentcointypes(alsocurrencies),sortinginformationetc.canbeassignedto
each block. Only one block at a time can be active and used for coin measurement and further
coin processing. You choose the desired block using the top switch block on the device (cf. Chap. 7.1
Selecting memory block (for double block data-management only), p. 28).
5.3 Accepted coin sensor
To ensure that accepted coins get to the cash-box or an external sorting device and that acceptance
isnottamperedwith,anacceptedcoinsensor(lightbarrier)checksbeforethecash‑boxcoinexit
[Fig. 1/6]/[Fig. 2/6] whether the inserted coin drops without hindrance through the coin outlet
towards the cash-box or the sorting device. Only when the coin has passed these checking
devices,doesthesystemeitheracceptthecoinor,inthecaseoftampering,transmitanerror
code to the machine (cf. Chap. 10.2.1.3 ccTalk error code table, p. 42).
Iftheacceptedcoinsensorsarecoveredpermanently,e.g.byacoinjam,coinacceptanceis
inhibited.
If the v2colibri is used in Casino mode, the coin validator cannot use the
accepted coin sensor in favour of fast coin acceptance. In Casino mode,
coin acceptance is transferred before the coin passes the accepted
coin sensor. This means that the coin validator's acceptance gate can
be tampered with, e.g. by a coin being inserted attached to a string.
5.4 String recognition
Toprotectthedevicefromstringtampering,theacceptedcoinsensorinthev2colibri is designed
such that coin acceptance is only transferred to the machine if the coin passes the accepted
coinsensorfromthedirectionoftheinsertfunnel.Ifacoinwaspulledbackonastring,the
system transfers an error code (cf. Chap. 10.2.1.3 ccTalk error code table, p. 42). Pulling back a coin is
alsomademoredifcultbythedesignofthecoinvalidator.
