Note: Channels higher than four cannot be individually inhibited, but will be globally
inhibited if inhibits 1 to 4 are inhibited.
It is possible to operate the BV100 in Low power mode with the Pulse interface. For
further details please see Chapter 5.
Credit Hold Function:
If this function is enabled in pulse mode by Configuration card or ITL BNV Currency
Manager Program, the validator will take the note as normal but then wait until the
escrow line is toggled low/high before. It will then give out the number of pulses per dollar
as set on the programming card. After the pulses have been given, the validator will then
wait for another low/high toggle until the full value of credit pulses are given.
For example with a setting of 2 pulses per dollar, a five dollar bill will give 2 pulses, 5
times.
A Typical use of this option would be for a Pool table with a game price of $1. You
could insert a $5 note and press a button that toggles the escrow line and releases the
pool balls, this would then allow you to play the first game. The Validator holds onto the
remaining credits until the game has finished and the button is pressed again allowing the
next game to begin, this continues until all the credits have been used.
The busy line remains low throughout the whole process and the validator remains
inhibited until all pulses are given.
4.3.7 BINARY OUTPUT – BIN
To use Binary mode the Binary interface must be programmed into the validator via the
Configuration Cards (See Appendix D – Configuration Cards) or via the ITL BNV Currency
Manager Program.
In the event that the machine needs more than 4 notes to be recognised, but the host
machine cannot take advantage of the serial communication methods then the BV100
can be set to give a binary pattern output on the four parallel output pins. If the BV100 is
set to binary mode it will issue the vend signals as a binary pattern on the parallel outputs
for 100 ± 3 ms. In this way a maximum of 15 different notes can be accepted and 4 notes
individually inhibited.
Vend Signals: (Pins 1 to 4). The four channels have their own individual outputs. If a note
is recognised the binary representation of the channel number will be pulled low for 100
± 3 ms. Pulses outside these limits will be rejected as a precaution against false triggering
due to noise.
Busy Output: (Pin 9). This is a general-purpose busy signal. It is active low while the
BV100 is in operation.
Escrow Control: (pin 10). Hold this pin Low to enable the single note escrow function. (See
Appendix E – ESCROW Control).
If the host machine aborts the transaction by setting the corresponding inhibit input high
on pin 10, the note is returned immediately.
The host machine can force the return of the note to the customer by setting the inhibit
line high, at any time before the end of the 30 second time-out. Setting all the inhibits
high causes a note reject.
In the event of a note being forcibly removed from the mouth of the BV100 during the 30-
second interval, the BV100 will go out of service for 45 seconds.
