AL55/66 Technical manual Version 1.1
Example of message string to enable all position for coin selector(
address 2
) is:
Host sends:
[02] [02] [01] [E7] [FF] [FF] [16]
Coin s. respond:
[01] [00] [02] [00] [FD]
ACK
After that all programmed coins will be enabled. Command has no effect on coin
position that are not programmed. Initially coin channels could be programed with
acceptance enabled or disabled.
For coin selectors that are using only cctalk interface, all coins position must
be initially inhibited!
6.5.2.11 Command 230 [hexE6], Request inhibit status
Coin selector respond with two byte data that correspond to inhibit state mask for all
16 positions of coin. If bit value is 1 acceptance of coin in that position is enabled. If bit
value is 0 coin is inhibited. Message format is:
Host sends:
[Dir] [02] [00] [E6] [Chk]
Coin s. respond:
[01] [02] [Dir] [00] [LSB Mask.] [MSB Mask.] [Chk]

after power-up or
reset is:
Host sends:
[02] [00] [01] [E6] [17]
Coin s. respond:
[01] [02] [02] [00] [00] [00] [FB]
Example of message string for coin selector(
address 2
) with programmed positions from
1 to 6, after receiving command to enable acceptance of all 16 position is:
Host sends:
[02] [00] [01] [E6] [17]
Coin s. respond:
[01] [02] [02] [00] [3F] [00] [BC]
First byte represent the mask for coin positions 1 to 8 and second for 9 to 16.
Coin channels(
positions
) that are not programmed are always represented as zero bit!
6.5.2.12 Command 229 [hexE5], Read buffered credit or error codes
This is the most important command used by host to detect import of coins in to a
machine and to report eventual errors. As previously mentioned coin selectors store all
events in volatile memory called credit buffer. Buffer has 5 level and use two bytes for
each event. In first byte coin position or coin value
38
is stored. The second byte point to
a sorter path or indicate error code.
If during acceptance of coin an error occur, stored value of coin position will be 0, hex
[00].
Error codes supported in ALBERICI coin selectors AL55/66 are shown in table 6.4.
