AL55/66 Technical manual Version 1.1
6.5.4 ALBERICI specific command
First command header for specific factory setting and testing is
255 Factory set-up
and test
. This command has several modes of use and some of them are factory secret
and are not explained in this document.
Beside this next chapter describe two modified cctalk commands
55
for encrypted
exchange of data between host and coin selector.
6.5.4.1 Command 255, Factory set-up and test
This instruction header is used only for factory testing and programing!
With instruction command header one data byte must be sent for definition of
command mode. Modes are:
- Mode 0(
hex 00
)
No description – reserved for factory use only
- Mode 1(
hex 01
)
No description – reserved for factory use only
- Mode 2(
hex 02
)
Read coin selector memory data
- Mode 3(
hex 03
) Write coin selector memory data
- Mode 4(
hex 04
)
Analog circuit test
- Mode 5(
hex 05
)
Coin parameter test
- Mode 6(
hex 06
)
Up-grade FLASH(
program memory
)
- Mode 7(
hex 07
) Re-initialization
First two modes are only for internal factory use and they are not described in
this document!
To use read and write instruction user must have basic knowledge about coin selectors
memory data organization
56
!
6.5.4.1.1 Command 255 mode 2, Read coin sel. memory
This instruction sends back to host block of memory data that was requested.
Data memory of coin selector is divided into a 6 group:
- Coin channel data
address hex 0600 do 06FF(
256 byte-a
)
- Input/Output data
address hex 0700 do 073F(
64 byte-a
)
- Factory common data
address hex 0740 do 079F(
96 byte-a
)
- User general data
address hex 07A0 do 07E9(
74 byte-a
)
- Statistic setting
address hex 07EA do 07FD(
20 byte-a
)
- Statistic counters
address hex 0800 do 083F(
64 byte-a
)
Factory key or user PIN protection are some time set to disable the access to some
blocks of memory. Usually all memory is accessible for red instruction.
On any attempt to read memory location that is protected without clearing key or PIN
protection mechanism, coin selector will respond with
NAK
message.
If number of blocks to read exceed block range, coin selector will also respond with
NAK
message. Maximum memory block read of 137 data bytes are limited by coin
selector transmit buffer that has 142 bytes
57
. If block size extend this number coin
selector will respond with NAK message to. Message string format is:
55
Commands 214 Write data block and 215 Read data block
