Bit positions for output test are:
-
bit 0 Output 1(
pin 7
)
-
bit 1 Output 2(
pin 8
)
-
bit 2 Output 3(
pin 9
)
-

)
-
bit 4 Output 5(
pin 3
)
-
bit 5 Output 6(
pin 4
)
-
bit 6 Output 7(
pin 5
)
-
bit 7 Not used
Unused output (
not programmed
) will not be turned on, but message ACK will be returned.
6.5.2.6
Command 237 [hexED], Read input lines
Coin selector responds with two data byte representing the state of DIP-switches and state of inputs In1(
pin 6
) and
In2(
pin 5
), if In2 is programmed as input. ALBERICI coin selectors has one or two banks of DIP-switches for various data
or operating modes setting. First data byte is state of first DIP-switch(
bank 1
) and In1, while second represent second
DIP-switch(
bank 2
) and In2. LSb is first switch in bank and MSb is state of input. Switch closed state is represented with
logic “1”, and input active state is logic “1”. Message format is:
Host sends:
[Dir] [00] [01] [ED] [Chk]
Coin s. responds:
[01] [02] [Dir] [Mask1] [Mask2] [Chk]
Example of message string for coin selector(
address 2
), with all switches “off” and inputs not active is:
Host sends:
[02] [00] [01] [ED] [10]
Coin s. responds:
[01] [02] [02] [00] [00] [00] [FB]
Example of message string for coin selector(
address 2
), with all switches “on” and input 1(
inhibit acceptance
) active is:
Host sends:
[02] [00] [01] [ED] [10]
Coin s. responds:
[01] [02] [02] [00] [BF] [00] [3C]
6.5.2.7
Command 236 [hexEC], Read opto states
Coin selector responds with one data byte representing the state of opto pairs.
ALBERICI coin selectors has up to 3 pairs of optical sensor (notice: in some case group could contain more than one
opto pairs) for detection of coin position, speed and direction and 2 pairs of opto sensors for diameter measurement.
Bit position for opto pairs are:
-
bit 0 Diam. measure opto 1
-
bit 1 Diam. measure opto 2
-
bit 2 Control opto 1
-
bit 3 Control opto 2
-
bit 4 Control opto 3
-
bit 5 Not used
-
bit 6 Not used
-
bit 7 Not used
Control opto sensor 2 is called “credit” opto sensor exist in all version of coin selectors and it is placed after the
acceptance gate. Other pairs are optional and some coin selectors has 2 and some 3 control optical pairs. Number of
control pairs make part of coin selector type label. For example coin selector type AL66V
2
has 2 control opto sensor
pairs. The unused bits or non existing optical sensors are always read as 0.
Interruption of light barrier of opto sensor corresponds to bit value 1.
Message format is:
Host sends:
[Dir] [00] [01] [EC] [Chk]
Coin s. responds:
[01] [01] [Dir] [Mask.] [Chk]
Example of message string for coin selector(
address 2
) with opto sensors cleared
is: Host sends:
[02] [00] [01] [EC] [11]
Coin s. responds:
[01] [01] [02] [00] [00] [FC]
6.5.2.8
Command 233 [hexE9], Latch output lines
This instruction is similar to instruction 238. Host sends one byte mask to determinate which output line must be
activated(
latch
). ACK message will be transmitted immediate.
Coin selector output line that corresponds to bit set in the mask will be latched and active till reset or new instruction with
bit cleared is sent. Message format is:
